Don Caithness Posted October 23, 2000 Share Posted October 23, 2000 I'd replace it to be on the safe side but then again who is to say the "new" diaphram will in fact be of lesser vintage. Unless you can purchase currently manufactured stock, might just go with what you have. Link to comment Share on other sites More sharing options...
davenc Posted October 24, 2000 Share Posted October 24, 2000 Should a NOS fuel pump, say as old as a 1930's vintage, be rebuilt before installing it? Could the diaphram still be trusted?<BR>Opinions? Link to comment Share on other sites More sharing options...
Guest scott mich bca # 6619 Posted October 24, 2000 Share Posted October 24, 2000 Any fuel pump thats more than a few years old should have the diaphram replaced. Just from time it can deterioate. You also want to make sure the new diaphram is a neopreme type, one that is compatable to today's gasolines, that have a good percentage of alcohol in them. Otherwise I have heard of a lot of problems with fuel pump failures due to the alcohol in the gas.<BR> Remember, it is a lot easier to repalce that fuel pump in your garage rather then alongside the road. A few minutes and dollars invested today, will save you a lot of grief.<P>Scott Link to comment Share on other sites More sharing options...
