electric fuel pump

Philip Littman · #1 01-16-2007

I have a PSC 34, 1998 with a 3jh2 engine. The electric fuel pump used for priming the racor after changing filters is no longer working. I believe it is a Walboro which does not seem to be availble now. What should be the replacement pump? Phil Littman

If it is a standalone 12v pump...just bring it up to your NAPA store and get the closest thing to it...it will work! Make sure your pump is between your Racor and the engine...NOT between the tank and the racor which causes pre-mature failures of the pump due to debris build up.

Phillip,
We have the same engine, mine being 1 year older then yours. (1997 Yanmar) and both were installed by PSC. My Racor 200R Spin-on Series Fuel Filter/Water Seperators for Diesel Engines Manual details the fuel transfer pump before the filter, not after it. Sorry Moderator, that's what is in print.

The fuel tank outlet(s) on my 1997 PSPH are positioned above the Racor Filter, hence may be the reason why I do not have the fuel transfer pump that is installed in your PS? Is your transfer pump located in the bilge area?

to act as a prime pump pump needs to be before.. fuel pumps can not generally suck air....

Jon...putting the pump before the racor voids the pump warranty AND causes lots of pump problems...(personal experience)...and it does work priming the system after the Racor if you have some fuel in the line which requires the pump to be mounted lower than the Racor. Worked like a charm when I made the move on my last boat.
