I just recently was on the dyno and my fuel pressure was dropping like crazy after 2000RPM causeing me to run lean and leaving me unable to continue my dyno session. HAs anyone had any issues with their walbro fuel pump?

Kind of pissed me off that they have no Warrenty on their products too, becuase if it is a faulty pump how do i know the next one will not be?

PS. It is a brand new pump less than 100km's on it

Can anyone relate? or have any insight?

there has to be somekind of warranty...most any product is covered by a warranty of some sort

I have a Walbro 255 hp, and notice that the noise of the pump changes from day to day. Sometimes the sound changes ( louder ) during a long drive. I have never dynoed my car, but that (drop in fuel pressure) might explain some of the strange bogging I get every now and again. My mechanic stated if the sound a pump makes changes it may indicate a failing pump. He also stated no warranty on the Walbro pumps. Is your car turboed?

Walbro Fuel Pump Warranty Info

Walbro offers a one year warranty against manufacturing defects on their in-tank and external high performance fuel pumps [i.e. GSS and GSL pumps] and 90 days on their bellows pumps. Previously, they were very forgiving with their policy. They simply told vendors to return the pumps and give the customer a new pump. Pretty much a "no questions asked" warranty.

In March, 2004, we were told by Walbro that they were no longer going to blindly replace fuel pumps that were declared defective by customers. This decision was made due to an extremely high volume of pumps tested (nearly 98 percent) that proved to be non-defective. Since then, pumps were required to be sent to Walbro for testing. Even though the number of returned pumps dropped dramatically, a vast majority of returned pumps were still found to be not defective. That testing was taking a significant amount of time/effort.

Walbro says that most high-pressure pump failures can be blamed on one or more of the following:

* Operating the pump without a pickup filter
* Operating the pump in a dirty tank/fuel system
* Operating the pump without fuel [i.e. dry]
* Operating the pump in a returnless fuel system where the vehicle controls fuel pressure by modulating the voltage to the pump [e.g. '99 up Mustang].

Starting August 1, 2005, Walbro has implemented a $40.00 charge per pump for testing. If you have a fuel pump you believe has failed due to manufacturing defects, return it to APE along with a money order for $40. APE will return that pump for testing. If Walbro determines the pump failed under warranty, we will send you a new pump and your $40. If you can't wait for the test results [usually 6-8 weeks], we will sell you a replacement pump, then refund your purchase price if the pump failed due to manufacturing defects.
