Great value for money for the fuel system at the moment

This worked fine for my setup. Passes fuel pressure tests. Only driven about 200 km with it. bought another pump to throw in the truck just in case.

Pros
  • Pleasant
Cons
  • Definitely bad product

The second is for backup.

The original one I bought for the jeep fuel system still works great. Bought this as a replacement. Getting stuck on the trail is no fun! I have it set at 48psi and it will hold it regardless of engine load. The pump is not noisy at all either.

Pros
  • Easy Installation
Cons
  • Appearance

Authentic Walbro 255 ๐Ÿ’ฏ

I can confirm that these are genuine Walbro 255s that I received. The oil in the bag has, as it should, a metal gear inside and a perfect embossing on the outside of the pump. You will receive a cold weather hose, 2 bolts on the ends of the fuel hose, and 2 bolt clamps and tails. This is ๐Ÿ’ฏ for me.

Pros
  • Lots of positive vibes
Cons
  • Cleanliness

I look forward to my return. 50% chance for this pump to work immediately.

Pump failed after one ride. Even with the fuel system shut off, this only pumped up to 45psi at idle, and when the throttle was pushed hard it dropped to zero. Sent the first one back in May and am still waiting for a refund. The seller did not respond to my contact request. December Edit: Still no credit on my account due to the return of the first pump. Pretty mad at that. The second pump I ordered has already done 500 miles and works well with my 600hp Fitech power boost system.

Pros
  • Quality construction
Cons
  • Modern

Traveled about a thousand miles

Put this to power an LT1 engine I transplanted to a 1984 Land Cruiser FJ60. Worked great but after less than 1000 miles from install it started to give way on a 300 mile ride. Luckily, I managed to carry him up the ramp to his destination, where he died forever. As I'm not close to home and my tools I've just bought a second one so I can easily swap it out BUT when I get home I'll do some extra homework and get something more reliable. I wouldn't advise taking this pump, but I'm not sure whatโ€ฆ

Pros
  • Few competitors
Cons
  • I don't really like it, everything is fine

Pumps gas like it's his job. Oh wait it is.

The pump works well on my 1984 Toyota Cressida with a 2JZGE+T engine swap. I highly recommend updating the fuel pump wiring if you are using this pump. it consumes little power. Also, this pump MUST be installed at or below the bottom of the tank. If you don't, it will cavitate and make all sorts of noises and the fuel won't pump properly. Ask me how I know. Once properly installed it is very quiet with a slight hum. If you have a bad fuel line, you'll know this right away, too, by tearing itโ€ฆ

Pros
  • Free for educational purposes
Cons
  • Only available in black

distinct piercing whistling.

Okay, bought this pump and replaced the broken one that comes on the frame of my Jeep Scrambler 84/4.0 Cherokee engine. while it works fine. In the future I will also install a specially tuned first built-in electric pump in the gas tank to avoid fuel shortage problems. I gave this pump 3 stars because it makes a consistent high pitched pitched sound. I've installed this pump in a tin box lined with cellular rubber insulation mat (supplied) and yet the whine is clearly audible throughout theโ€ฆ

Pros
  • Absolutely amazing!
Cons
  • Guard

First DOA. - Fuel pumps and accessories

Arrived soaked in grease that should be inside the pump, not outside. Even the silica gel bag was wet. I installed it anyway. It worked fine for the first few minutes. The pressure on the gauge under my hood was strong and stable. At first the engine pulled hard. Everything changed in 10 minutes. The pump began to emit a piercing screech. The engine died on the freeway. I was able to hobble home with a few more unscheduled stops. During operation, the pressure gauge jumped wildly and showed low

Pros
  • GOLS certificate
Cons
  • Nothing here
