Fuel Pump

[Norm Knowles]

From reading earlier comments on the Forum I know I have a AC588 fp on my 48 Dodge D25C.  While ideling I noticed it leaking a fair amount.  Was unable to see exactly where when looking from above and below so removed it.  Cannot see any obvious place as a source of the leak and it was not from the glass bowl.  Any thoughts as to what may be the problem or should I replace it?  Thanks for your help

If it were me, I'd be more inclined to rebuild it or have someone else rebuild it if your not comfortable doing it yourself. A lot of the new replacements available out there are not great quality wise. Also, make sure the problem isn't the flexable line running from the frame to the pump itself. If it's as old as the car,it could easily be leaking and making it look like the pump is the source of the leak.

There is a weep hole in the pump. when there is a problem with the diaphragm it will leak at the weep hole as well as allow fuel to pass beyond the cam lever into the crankcase.

But, when is occurring this leak in this weep hole,the engine has too a lack of power,ok?We have to check if the leak is not with oil.

Check with the good folks at Then and Now Automotive (a.k.a. Antique Auto Parts Cellar) for a rebuild kit for you pump. http://www.then-now-auto.com/fuel-pumps/ They are pretty easy to rebuild and their kits use quality rubber components that are compatible with modern fuels. Also, their kits use a pivot pin with circlips to retain it so you won't have it walk out on you like an off-the-shelf replacement pump will do.
