Anyone have any luck using a Quantum fuel pump? A buddy is on the 2nd one, both will not pump enough fuel to get over ~4K RPM on his 07 GSXR1K. It will idle fine but once you rev it, it dies. We put a known good tank w/ OEM pump on and it runs great. Are we doing something wrong, or are their pumps junk? The OEM unit cost 400$, the Quantum unit was under 100$.
Hmmm, an e-Bay thing for 1/4 the price that doesn't work well. Shocked? What is your fuel pressure? I have more than one bike come in where I found the wrong regulators (10 psi under) in the assembly.
I've run quantum pumps on 2 gsxrs and both seemed to be fine running up to maximum speed/rpm. Although one is maybe slightly slower than it should be.
They may be on Ebay but this was purchased from the company https://www.highflowfuel.com/, seemed legit
High pressure filter, toss it in an ultrasonic cleaner, along with your injectors and back flow it a few times
I've had good experiences with the Fuel Pump Factory, if you're looking for a supplier other than OEM https://www.fuelpumpfactory.com/
In your tank. pump slides into the bottom of it. it has an internal filter for high pressure side of the pump. notorious for getting plugged and causing high rpm starvation of fuel. some people back flush them but i found replacement units on Amazon for $27 vs the oem cost of $300 , its a suzuki hayabusa replacement that should work on your application also.
