I have just registered as my husband is in process of restoring a Humber Super Snipe 1950 but is having problems with the fuel pump.

Maybe we need to know more about it the nature of the problem but
I think the Super Snipe just uses a simple AC mechanical fuel pump that is driven off the camshaft. If he unbolts it and checks the diaphram and its return spring and that the little petrol valves are opening and closing then there isn't much more to go wrong short off the lever arm being broken.

Hi

This is an example of the sort of simple mechanical pump which Peter has mentioned.
Another problem I have seen is where the down shaft through the diaphragm has not been twisted through 90 degrees to engage properly with the slot in the end of the lever.
Another model I have had has a much shorter lever, which barely protruded from the body of the pump and was activated by a straight rod from the cam shaft and I know some one who didn't put the straight rod back in and wondered why the pump didn't pump. Embarassed

Some pumps have a priming lever sticking out opposite the activating lever, if you have one of these and it doesn't pump fuel through then I would suspect the valves might not be seating properly or the diaphragm could be perforated allowing fuel to get into the crankcase.

Thanks Penman and Peter. They haven't yet got the hang of posting on the forum but sent me a message thanking us and telling me they had found a split diaphragm. They're wondering where to source a new one from.
Best I post them a link to this page.

Don.

I believe their Humber uses an AC Type T pump but I can't find any diaphrams for sale. However, I think the diaphram in the U series pumps is probably the same, so it might be worth taking a risk on this if it looks familiar:

If you missed out on the eBay kit that says:

"For AC Delco type U and Type F fuel pumps.
As fitted to Triumph TR2, TR3, TR4, TR5, TR6 and GT6."

Rimmer Bros kit for a GT6 should be the same as the eBay one..

Pigtin. if they are really in the fertiliser, I believe I have a couple of NOS AC diaphragms for a Type U.
