Hi,
Does anyone know if the fuel pump filter can be removed without removing the pump from the car? It looks like it might be possible....
Thank you,
Pete

Re: Fuel pump filter removal
Yes I have removed my filter, but is a bit tricky as its very hard to see the filter cover as under the pump. Just make sure you have a good washer to seal when you refit.

Re: Fuel pump filter removal
As filters go its not the best in the world. I'd check your float chamber for silt at the same time too.
Glad to be back!

Re: Fuel pump filter removal
Thank you for your comments and advice. The filter and its housing did have a lot of stuff that looked like coffee granuals in it but the pump still runs too rapidly to my mind. There is no leak anywhere that I can see and it stops ticking when the float is full (ignition on, engine not running) but is very busy clattering away, especially when accelerating. Bit noisy too.
Any thoughts - a perforation in the diaphragm, perhaps?
Also, while I am here, any suggestions on how to get the valve cage and its contents out? I'm looking at a spare pump I have, and these parts seem to be stuck in the pump inlet housing (that is, inside the aluminium body of the pump). I want to check its OK before I try it as a replacement (it does tick nicely when connected to battery power).

Re: Fuel pump filter removal
Have a look at this thread: http://www.mmoc.org.uk/viewtopic.php?f= ... 66#p532971
Valves are on the other side from the filter. Unscrew the spigot where the fuel line to carburettor attaches. One valve is held in by a circlip, the other is further down. It may well be stuck but you can poke through from the fuel filter side.
If you are going to this trouble it would be as well to fully overhaul your spare pump with new diaphragm, gaskets, fibre washers and points.
Coffee granule stuff is rust from the tank.You may well have a partial blockage in the fuel line from the tank or the pick up in the tank.

Re: Fuel pump filter removal
Thank you for that. The valves are now out but washers look very ropy
Also, back to my question as to whether anyone knows if a split diaphragm would make the pump work overly hard? It does seem to beat very fast most of the time.
Thanks

Re: Fuel pump filter removal
A split in the diaphragm would make the pump ineffective and work overly hard but it could also allow fuel to leak past the diaphragm and up to the points where it can be ignited by the spark at the points. The diaphragm could well be partially stuck or hardened and seeing as you have seen rust in the filter the pump is probably full of rubbish. The pump will also work very hard if the fuel line from the tank is partly blocked.
