Info needed: Fuel pump rebuild.....what time is it? modern fuels

[Alex van de Wetering]

Hi Everyone, thanks for all your reponces, comments and suggestions. For now my plan is to use the original mechanical equipment....like Bruce I enjoy working with the old mechanicals and making them work. Maybe in the future I do decide to upgrade to an electric pump (with extra switch!).

I once salvaged about a dozen pump overhaul kits for the M38A1 jeeps which were heading for the garbage can

Rob, actually I think the rebuild kit I bought is intended for the NEKAF, the Dutch version of the M38A1!

The holes shouldn't be a problem. How different is he height of the shaft? Is it within the throw of the lever?

Bruce, I was hoping the attached picture would clarify the difference, but sadly it doesn't. From memory there is about a 2mm height difference in the rectangular hole between my original (that's presuming this hasn't been replaced in the past) and the red replacement (measured from the metal plate).

I think Lynn is right on it resulting in a different pump capacity, so I was planning to do a quick zap with the MIG and adjust the hole with a file to match the original.

you certainly do not want it to leak petrol into your sump.

That's another thing.....my base has 4 holes in the lowest part.....presumably to drain fuel in case of a leak? The other base I have does not have these holes???
