MG TD TF 1500 - Fuel Overflow Pipes

Does anyone have a pic of the proper routing for the fuel overflow pipe coming off each of the carbs. The exhaust pipe is down there!
Thanks, Bill

Bill Reid TD4618

The correct path is shown in the drivers handbook Bill. I have a few pics from a number of cars that show the correct path & the clip that secures them forward of the member that the engine is bolted to. I'll dig them out & post them later. Cheers

Bill-
I just sent you ten photos of the overflow tubes via email.
Cheers,

Thanks, Roy....

Got them.

Wouldn't mind seeing the pics myself...Any chance of posting a couple here.
Thanks

I don't know Bill, I think that the way you have them is quite artistic :-) Cheers - Dave

And here's a picture of the end of the pipes and the clip holding them.

I have a couple of other original path pics from a one owner TD here in Sydney however they are too large to post & I have no idea how to reduce them to a 'postable' size. They show the path OVER the bracket & the detail of the clip confirming Joe's post above. The shot above is of my car. There are some who are of the firm opinion that the lines descend aft of the bracket & go through the hole at the bottom. I disagree & feel that the Drivers' Handbook & original cars like Joe's are correct. The line on Joe's front carby however I believe should be at right angles to the block where it exits the float bowl (i.e. parallel to the rear line, as shown in the handbook). I've chosen to use the path (see my pic above), which is clearly illustrated in the Driver's Handbook. The bespoke 'P' clip is yet to be fitted. Cheers

Clip, huh? My PO had them passing through the hole in the front engine plate.

Live and learn.

There are some original factory pictures with the tubes passing through the hole. See the archives for this debate. I recall that either way may be "original", but that going through the hole would be pretty hard to do on a production line. George

If you have Windows you can use the snipping tool. Bring the picture onto your screen, cut it with the snipping tool and save the picture with the snipping tool.

The snipping tool is very useful and easy to use. That's what I used for the images I posted above. I'd had my computer for years and didn't know it existed until someone on this forum mentioned it as a solution to the same problem Peter has.
Joe
Joe Olson

Still beyond my skill level. Windows 10 has a sniping tool buried somewhere.. I couldn't figure out what those who supplied the answers when I Googled it were on about. My son then copied the images into Paint & then resized them. Hopefully they'll repost now. I've no idea of one of the sources so can't provide a credit. The other two belong to a Sydney owner whose father bought the car new. Pic 1 below. Cheers

Could someone post the illustrations from the Driver's Handbook? That would help those who don't have a copy. I completely agree with George's comment 'that going through the hole would be pretty hard to do on a production line'. The old axiom 'time is money' has always applied. Cheers

Also worth noting Bill that the rear line is/should be appreciably longer than the front. You may have two that are the same size. Cheers

Interesting to note that in the Driver's Handbook illustration the rear choke overflow pipe passes in front of the choke mechanism.

Peter's Pic 1 is of my car after its blessedly leak-free rebuild.
Joe
Joe Olson

Hello Joe

is it really leak free? No smell of gasoline, no moisture at the jet assemblies - in other words "dry like dust"?
W_Mueller

This is going to create controversy however the most detailed images I have encountered, they refer to a YT.

http://www.mg-cars.org.uk/imgytr/technical.shtml

You will find you have to scroll down to find them.

Plenty of good advice that is relevant to our marque to be found here.

Graeme

Hi Graeme. Why any controversy? The article you reference states, "The overflow pipe(s) - there are two on a YT, should pass over the front engine plate and through a retaining bracket on the front of the front engine plate." That is what is shown in the Work Shop Manual and the Driver's Handbook. The article also states, "However, after doing a decoke or any head work, refitting the pipes so as to pass through the clip on the front side, and the clamp bolt be tightened, would be a very time consuming process. The more usual position for this clamp therefore is for it to be found in a totally horizontal plane on the rear of the front plate or carburettor side. "I don't find that controversial at all. It confirms the factory installation method and an owner modification. Am I missing something?

Regards

Tim
TD12524

That is a good site by the way.
Tim Burchfield

On both posts by Graeme & Bud, (as well as the Driver's Handbook,) the pipes do avoid going through the hole. They both show the pipes on the aft side of the plate, not forward of it, as I believe & as the article suggests they were originally. As you state Tim the article makes it clear. However viewing the pics without reading the text may permit an erroneous & hence controversial conclusion. Cheers

Peter. Good point. On another subject, I replied to an email you sent me a few weeks ago and it appears it got kicked back. Is your email the same?

I think factory photo of TF powertrain, with overflows going through the hole in the bearer plate. I think there are pictures out there somewhere of an original TD showing the same, and definitely others showing over and in front of the bearer plate. Seems that going through the hole on an assembly line would be a pain on the , so over the top and clipped would make more sense. I personally think they may have been done different ways on different cars at different times. George

George Butz

Mr. Mueller,
I'm happy to say that yes, indeed, the engine and carbies are dry and free of any gasoline odor. There is a drop or two of oil from the vent pipe after a run, but that's it. The Moss seals, FTFU's modified speedo pinion, and Hylomar on all the gaskets have worked miracles.
Joe
Joe Olson



... and your seals came from?
W_Mueller

sorry - not complete

The sealing kit I got seems to been from Burlen because the adress mentioned in the instruction sheet is the same as Burlen.


Has Moss its own?
W_Mueller

Tim

My concerns were not pertaining to the content of the post it was where the information was sourced from.

Sometimes the blinkers are on if posted information does not stem from original TD/TF documents.

Graeme
G Evans

Graeme, very sensible philosophy, especially in the era of Fake News. It turns out that the information on the site you provided conforms to the drawings in the Driver's Manual and the Work Shop Manual. So I think we can conclude the information on the YT site is correct.

Regards

Tim
Tim Burchfield

The pic of the TF George does suggest that some may have been routed that way. Seems weird though considering that method would requite two right angled bends really close to each other. Difficult to fit & to remove especially on the assembly line where motion is the go & time is money.
Cheers
Peter TD 5801
P Hehir

Not so difficult owing to the ease of bending the copper. I installed my vent tubes through the hole fairly easily, with the engine and everything else in place. Didn't bother with the clamp though.

Very helpful thread. My pipes go nowhere near the correct direction currently. I did check and the clamp is very much in place, so will get to re-routing them this weekend.
S Griffin

On The Original TF midget gallery photo,Engine Compartment Details,
Photo No.089,there is a clear depiction of the overflow pipes going through the bearer plate hole with clip.

Note the overflow pipes are steel and not copper.

Then it seems that the TD & TF must have had different paths Rob. TD barn finds, DH & WSM all suggest over & down the front of the bearer plate & secured with the clip. Is there an illustration in the TF Driver's Handbook? Cheers
Peter TD 5801
P Hehir

Peter,

George Butz's Factory photo of the TF motor/gearbox confirms
the route of the carb overflow pipes. Original TFs I have seen over the years also had the pipes going through the hole in the front bear plate and then clipped (brass) the same as TF9052.

With reference to the TF Handbook,as you know it is not an accurate reference in many ways. The page 66 sketch does show the pipe going over the front of the bearer plate. Looks like the Handbook expedient personnel just copied the sketch from the TD Handbook ?

In the TF Handbook,there is also incorrect sketches of the instrument knobs(should be octagonal in form) ,chain missing off the Rocker Cover cap, a suppressor on the bulkhead rather than a wiring harness clip,breather pipe wire type clips from rocker cover outlet to carb. compared to the Jubilee '0' size clips that were used.(the Service Parts Manual depicts the Jubilees). The production phase TF had quite a few changes from the prototype.

Cheers

Thanks Rob. I defer to your extensive & detailed knowledge of the 'TD with the pretty face' :-). My TD Driver's Handbook shows that that subsequent editions did show some changes as TD production continued. I have a later TD handbook showing round tail lights, changes to the switches on the dash etc. There is also an illustration of the front suspension that the printer has inverted. I'd love to find an early edition just to compare them. It would also be informative to see what the path was on the TC. It's possible some of the illustrations in the TD handbook may have simply been recycled. Cheers

Peter,

I will talk to Mike Sherrell soon about the TC overflow pipe route. He of course wrote the informed book 'TCs Forever' which has been sold worldwide over many years. Mike is a local MG club member.

Cheers

Peter,

Just on a fine point,the overflow pipe of the carby closest to the bulkhead goes toward the engine side panel from the fuel bowl lid,whereas the front carb. overflow pipe is directed to the motor side
of the lid to then travel downward on the original TF set up !

Cheers

W_Mueller - We're kinda hijacking this thread, but in answer to your question about the origin of the seals in my car, they all came from Moss: Front and rear engine seals as well as the carb rebuild components. I used their 0-ring seals instead if the cork jet seals. I don't know where Moss gets their stuff from, but so far, knock on wood, my garage floor is dry.
