Questions & Answers Ask a Product Question
Q:

HI, I need a fuel pump for my boat, it has a 1995 454 gen v engine in it . will this pump work well for this motor , or is it something else you recommend

Asked by on July 03, 2017

A:

I used it for Gen 4 GM 454 engine, and it works fine. The BIG issue is that MUST be mounted in vertical position using bracket supplied. Many OEMs used to provide engine with horiz mount pump, latest pumps and fuels FAIL in Horiz position . Also, NEVER allow ethanol tainted fuel anywhere near pump, regardless what it says on box.

Q:

I have a 2000 ski boat with a Holley carb engine. The mechanical pump was taken off for a electric fuel pump. There was a old school primer bulb in front of the pump in case it died. I read maybe installing this pump back near my tank will ensure when I go to start my boat there will be fuel in carb so it will start. Does this sound correct? Is there any thing I need to do when installing like horizontal or vertical? Do I take my other pump off and just go with this one or keep it installed

Asked by GARTH on June 24, 2018

A:

USCG regulations require that the pump be withing 12" of the engine. The fuel line from the tank needs to be under suction rather than pressure. I took my mechanical pump off to replace it with this one. Haven't got the boat running yet though....

Q:

P4389 housing is ok to replace a mechanical pump and power a V8 5L7 with a 710CFM holley carburetor?
the flow is enough?
there is no return to the tank the pump will not be too much pressure and will not force too much?

Asked by YANNICK on May 04, 2018

A:

This pump will work perfectly for a Holley carburetor, it is preset for 6 psi and will supply plenty of fuel. I use mine in a jet boat with a 750 QF on a 454 BBC.

Failed after 10 months

Purchased this pump, has good flow and pressure, the check valve went out first, then the pump lost all pressure, total failure, thankfully I was at the dock and not miles away. Failed after 10 months light use.

This fuel pump showed up at my door 2 days after ordering. It bolted right up and worked like a champ on my boat. I am very satisified with my purchase.
