fuel pumps
I received an original fuel pump from a 1950 f5, and have the elec fuel pump that was in my 1948 f5. Wondering what the benefits are of each and the drawbacks? The elec pump is chattering but does not seem to push fuel, can this be reworked, and are there guidelines for cleaning, using the orig type fuel pump? Appreciate any help, advice!

Guys usually install electric pumps to eliminate "vapor lock" but in 10 years of running my daily driver 48 F1 with the flat V8 I've never encountered that dreaded disease. I have had fuel lines plug at the tank, fuel filters plug up, etc.
During those 10 years I've been using the same mechanical pump. I can't see anything wrong with the original equipment.
Go electric if you want to, but it isn't necessary in most cases. Your local parts dealer will sell you a new electric pump and I do run an electric on my 52 plow truck, but it also was fitted with a 360 by a po. Either way you go will get you down the road.

Just to clarify, an original type pump with modern diaphragm materials is likely adequate. The original type diaphragms can't handle ethanol and all the additives in modern gas, turns them to gum quickly. Same for the gasket on the stock pump's glass bowl. One I got from Dennis C. turned to goo in 15 minutes running time (this was 10 yrs ago). If your truck is 12v, personally I'd go for an electric pump, just because they are all made with modern materials.

I have a NAPA replacement on my '51 flatty, $60, works good, lasts a long time, no wires or anything, Just me, but I wouldnt waste my time rebuilding one when they are that cheap and available locally. J

6V2404, I do not see a manufacturer stamp anywhere. I have it out of the truck now, but my camera batt is dead, I can load some more later.

Geoffrey, the 6V2404 appears to be a Walbro, bellows type pump. As far as I can tell, they used to be sold by J C Whitney, but are no longer available. I believe that Walbro is now part of Federal Mogul, so you might try NAPA or another parts store for rebuild kits. Some of the folks on the Antique Auto boards have pretty low ratings on these pumps.

Thanks for the tips guys! Will continue to research, wish I had time to work on this this weekend, have to go to Vegas though. What I really need is to get er towed to the house so I can work on it at 4:30 am instead of sitting on google all morning!

Are you running 6 volt still? The glass bowl gasket that came with the e bay pump was oval shaped and snapped the other day. Dern it.
