Can't recommend them. Yeah they are cheap, and yeah you get what you pay for.

Recently replaced the fuel pump, fuel lines, fuel rail, fuel filter and injectors in my car. The tank was replaced two years ago. The prior pump that was in the car for 2 years with the new tank was a walbro as well. It was a prelude pump which I had rigged to fit in the crx fuel tank. Figured since I was taking the tank out to do fuel lines I would go ahead and put the proper pump in as well. Bought the pump, and not even 500 miles have passed and it is making a loud grinding noise.

Walbro will "inspect" the pump for $40, and if what most are saying, will then keep the $40 and tell you that it is your fault and will not warranty the pump.

It will be replaced with a used oem prelude fuel pump...which will outlast and and produce more than enough flow for my 140ish hp engine.

Walbro is dealing with a bunch of cheap imitation imports from China, hence there $40 inspection fee.

What pump did you buy and from where? Walbro's are noisy, esp. below 1/4 tank. You will never question again if the fuel pump is cycling because of a bad main relay.

GSS341 with the matching install kit, purchased from Lighting Motorsports (been dealing with them for a decade now without a problem, ever, already called them and they offered to sell me another at their cost since they know Walbro takes $40 and says its your fault), and they, as far as I know, are one of the largest sellers of Walbro pumps around.

I have used Walbro pumps off and on in my personal cars for about 12 years, and am familiar with the loud whine they make compared to stock.

The pump is powered off of relay with direct power from the battery (the original power line is the relay signal input).

This car was run for about 50-60 miles before it was in a minor accident (left front corner) and sat for 6 weeks. It was just below a 1/4 tank at the time as it had not been refilled since the entire fuel system was replaced. Two nights ago it was driven to the gas station and a full tank of 93 octane put in, then tuned, and has been driven to take a kid to school 2 days in a row.

The noise is not a whine, it is a grinding noise that is loud enough it can be heard on a cell phone. The pump has less than 6 hours of run time. A prior walbro pump had run in that tank for 2 years without fail.

The issue is with the fuel sock. The provided sock does not sit flat on the bottom of the tank and below 1/3-1/4 range it will "grind" as you mention because the fuel doesn't completely cover the sock. If you run it like that long enough, it'll damage the pump.

Fill the tank above 1/3 and no noise (unless you let it go low for too long).

Walbro pump + OEM sock = problem solved.

I have mine with OEM sock and mine runs fine to empty. I dont run it bone dry, but when the light comes on, i gas up. No issues yet.. knock on wood



Edit: I did run Xeno's brand of pump when i 1st went boost. They claim its just like a walbro. Im not knocking the company, but I had nothing but problems with it and fianlly it took a shit, my car ran lean and cracked a sleeve. Of course I called to complain their pumps were garbage and got a "we never had one person have an issue with them" line. Lesson here; to save 35 bucks, it ended up costing me 1200. I put in the Walbro and never had an issue since!
