Works with my gen 4 zx10r
My gen4 zx10r is close to 15k miles and I decided to do some maintenance and changed the fuel pump as well. Fuel pump quality was really good. Comes with all the filters and o-rings you need to do the install. Installation was easy and straight forward. Functions as it should and it looks really sturdy and well made. I dont really have problems with my bike starting but it fires right away after installing the pump. Recommended pump and it might not be OEM but for the price, you cant really complain.

Easy to install
My fuel pump showed up as expected. It was easy to install, as it came with everything needed for a few different applications, and it works perfectly. Very happy with this purchase and it was about ⅓ the cost of local parts shops.

Does not fit 05 xb
This pump did not fit a 2005 Scion xb. The pump was too long , it did not fit the canister. Among other fittings issues due to pump size.

Amperage?
I was searching for a fuel pump to replace my 25+ year old Walbro 255. I initially found the Walbro pumps, but also saw this pump. I bought this one instead as the Walbro old design (read as 'not made in China') pumps are hard to get at a decent price. Even the ones made in China are way too expensive... I decided to "gamble" on this one. It is made in China, but at least the price was decent.Out of the box, It was a great looking pump.I was able to swap the pumps with very little effort. The old Walbro connector fits this pump and is polarized the same. Negative to negative and positive to positive. That made swapping really easy.I got all the connections done and ran the pump. It hit my goal of 52+PSI without engine running (Primed). It only dropped to 48PSI with engine running at WOT. It kept the fuel rail supplied and kept the engine happy.I went to test drive the car and the pump shut off after 1 mile. It had blown the 10A fuse. I felt the 25 year old fuse was on its way out anyway... I replaced the fuse and watched the new one. It got very hot after 5 miles, too hot to touch comfortably. The new fuse was about to cut the circuit after 10 miles; it was so hot I could not touch it without burning my fingersI guess this pump is not as direct a "fit" as I was lead to believe, circuit wise... This pump runs at more than 100Watts of energy. I stepped up the fuse to a 15A, as I am using 12Awg wire.Hopefully, this is a "break-in" thing.I really like the pump. It is a good value for the money. I can't say anything about longevity, yet. If it lasts half as long or as long as my old pump, I'll be ecstatic!
