MG TD TF 1500 - install a Fuel Filter

Did somebody install a Fuel Filter like the unit shown in the enclosed picture?
My plan is to install it in the coper pipe in front of the fuel pump. Make it sense to do so?
Thank you
Guenter

Guenter, on my TF I have the filter up near the feed to the carbs, the reasoning is you can see it plus it's easy to get to. My TC has one on the frame near the rear wheel, hard to see and harder to replace.

Hi Guenter

Well worth it, as Don says put it where you can see it and clean it easily.

Mine is in the feed to the carbs...

Hi Guenter,

beware of this type of filters! Although looking neat, they are made of cheap Zinc cast with nice Chrome plating but tend to get cracks soon. I learned it the hard way.

If you are concerned about dirt from the tank might reach the fuel pump, put a larger filter in the line just close to the tank. Have a look on the installations used on motorboats and small yachts. They have very usefull solutions for our cars and are cheap and of good quality.

A nice filter for the engine compartement is the one used on XK MK1 Jaguars. it is fitted between the pump and the carbs (where it is more usefull than between the tank and the pump) and has a small shut off handle and a exchangeabel paper element in a glas bowl. Labeled AC, it Looks quite right for a TD.

Guenter, Make sure you mount the filter on the pressure side of the pump, not the suction side, reason, should the filter clog up, the pump, most likely will be damaged receiving no fuel. If on the pressure side, the pump will merely shut off. PJ

Just a question. Is an additional filter going to do anything useful? You already have filters in the tank, the pump, and the carbs.

"Make sure you mount the filter on the pressure side of the pump, not the suction side, reason, should the filter clog up, the pump, most likely will be damaged receiving no fuel. If on the pressure side, the pump will merely shut off."

Paul has it correct. If a high efficiency filter between the tank and the pump, a clogged filter will cause the pump to stall in a current on condition and will (at the very least) burn out the swamping resistor inside the coil housing. This in turn will result in a higher than normal arcing at the points, causing accelerated erosion of the points contacts.

"Just a question. Is an additional filter going to do anything useful? You already have filters in the tank, the pump, and the carbs."

Dave H. also has it correct. Both the SU fuel pump and the carburetors are quite tolerant of fine debris that will pass through the factory installed filters. The factory installed filters are there to stop the passing of rocks and small birds (to quote a expat who became a close family friend). Cheers - Dave D.

Here's an alternative to an in-line modern chrome-glass or plastic fuel filter under the bonnet:

Jaquar, Rover, etc. used a classic glass bowl fuel filter that bolted to the firewall or fender, often made by AC. They were made for fuel inlet on either the left or right side of the cover, identified by a "L" or "R". And no, I don't have one on my TF.

The filter housings and elements are available from classic Jaguar parts suppliers, on ebay, and other sources. Search Google and ebay for "Rover glass filter" or "Jaguar glass filter".

Here are a few ...

That's what is called a settling bowl, all my farm tractors have them, some tractors have two, but the good ones have a porous stone element inside to filter out fine particles. Old technology and work well, but with all the modern filters out there, I wouldn't put one on a car today. JMHO. PJ

Actually, the bowl filter is the best. Easy to see sediment build up, easy to open and clean, and best of all fully modern as the new ones come with pleated paper filters which do a great job of filtering. Great peace of mind.

I have a Durex Moraine #986640 glass bowl fuel filter on my 1954 Chevrolet 3104 pickup. It has a bronze filter element. Period correct and works fine (at least I guess it does.)

When I first got my TD, back in'66, it had a glass bowel filter. It still does.
New element and gasket.

is the unit I have in my MG. It's modern and takes inexpensive pleated paper filters that really filter out the small stuff.

I should add that my very faulty memory thinks it's probably standard US 1/4 pipe thread...

The benefit of the paper filter material over the stone filters is they are a throwaway and the stones need to be washed periodically and a pain. PJ
Paul161

I think the paper also traps a much smaller level of particulates.
