MG Midget and Sprite Technical - Filter King Regulator

Hi
Just about to fit one of these just wondered if anyone had and where you put it in the engine bay , pictures would be a great help

Cheers

they can go anywhere convenient. my fuel system was all non standard, but I fitted as high as possible on the firewall away from radiated heat.

Just wondering
why would you fit one?
Onno K

Onno to be totally honest just wanted a decent filter and had some bits to return to local shop and this was what they had , not really bothered about regulator side but came as all in one and thought looked smart .

You have started me wondering about just a filter now !!

Not ment to do that!
I've just never found a need for a regulator on a NA car and was wondering what made you.

They do look smart.

I'd just never add something that could fail in to the chain of parts that make my midget go unless it has to......
Onno K

Some pumps produce more fuel pressure than the carb (Weber DOCE) likes and the regulator solves this problem/potential problem.

It is a large fuel filter so filters out crap, especially from an old tank on an old car.

You can put it where it will fit. Mine is in the engine bay but one day I might move it near to the pump at the rear of the car to minutely improve the centre of gravity of the car - many a mickle makes a muckle!

But would a pump suited to the carb not be a better option?

More modern replacements such as Facet silver tops produce too much pressure so need a regulator. Very few aftermarket pumps will produce low enough pressure for SU or Webber float chambers. My Caterham runs 2 40 DCOE webbers and has a Facet fuel pump with a regulator close to the carbs.


Robin Cohen

An SU pump should deliver a good pressure.
Also the facet cube pumps are available in lower pressure values.

I am not trying to offend any one.
And if a fuel system needs a regulator it should be fitted.
I do think that 9 out of 10 times use of a regulator can be avoided.
And less parts in the chain that make a midget go that can fail can only be a good thing. Right?!
Onno K

I have a filter/regulator mounted on the inner wing, near the top, just behind the expansion tank. As I like to alter between SU's and webers I can adjust the fuel pressure to suit.

Hi Andy,

I’ve recently had a “filter King” filter/regulator fitted to my car, for a number of reasons it’s a better filter than the one I had fitted previously (found a load of crap in the crab) although the old filter probably should have been changed a year or so before! The other main reason for fitting a regulator was that my electric fuel pump was pushing out to much pressure (6psi) for my crab (Webber 45) which apparently only requires 2-3 psi and it does warn you in the fuel pump instructions (which I read after fitting the pump) that a regulator may be required.


My only complaint about the “filter king” filter/regulator is that you need to make a bracket up for it to fit to the car (see photo) the alloy bit is the “home made” bit. Otherwise I have had no problems with the unit, even though it is a large “glass bowl” storing a lot fuel in a hot environment, so an initial fear was that the fuel would get hot and cause all the known issues for fuel vaporisation.

Many thanks guys , Richard no photo ?

Andy,

I will try again to up load some photos, I forgot to save the photos in a different format that has a smaller file size! Tech one day I will understand it!

Andy,

Last one!

I had a filter king on one of my cars. It was erratic on pressure control (sometimes cutting it off completely). Others on this side of the pond have complained of similar problems with this unit. Like Onno says, best to have the fuel pump matched to the carbs. In the US, it seems that pressure regulators that cost less than 75-100 dollars are borderline junk.
JM Morris

Agree with Onno. I have a silver top Facet feeding standard SU's and have never had a problem in 15 years. It all ticks (sic) along merrily!

I've a Q&H electronic traditional style pump

with disposeable plastic filter, quick, easy and cheap to replace, you can see if petrol is in it so useful for diagnostics too and it's very unlikely to play up or go wrong
