Walbro electric in-tank fuel pumps are available in a variety of flow ratings, including pumps that flow significantly more fuel at higher pressure. The outside dimensions, however, of many pumps are compact enough to fit existing hanger assemblies, without modification. All pumping components have been validated to OEM specifications for use in E85/flex fuel applications.

Most Walbro in-tank fuel pumps utilize a proven gerotor design. Some high-performance models, including those designed for engines with more than 750 hp, feature a dual-channel turbine design for maximum efficiency in high-pressure and high-temperature applications. The blades feed two high-pressure pumping channels, as opposed to a conventional single-stage pump that uses an impeller with a single row of blades at its outer edge. This innovative design results in improved hot fuel flow, as well as minimal noise and current use, resulting in efficiency that's higher than conventional pumps. Some pumps require modifications to system wiring, fuel lines, and the fuel module, and should be professionally installed.

Installation kits including a fuel strainer, fuel hose, harness pigtail, clamps, and wire connectors are sold separately.

Q:

I need a pump that will supply 255 ltr/hr at 43-58 psi with a max of 90 psi (edelbrock pro flo 4 going in a 90 GMC Jimmy w/ 383) Do I need to run a pressure regulator?

Asked by JOHN on January 07, 2019

A:

I have a Chevy 5.3 engine with a Texas speed cam stuck computer and flex fuel injectors at 55 PSI so the engine is running a little rich with the Walbro fuel pump and factory regulator on the fuel rail. These fuel pump is good for your application, I will use the regulator to help with the tuning.

This Walbro kit GCA-758-2 fits 80's-90's era GM cars/trucks. It installed into my 89 IROC Camaro with no issues. Before purchasing I did some research. There is a lot of confusing/misleading/opinions out there so I wanted to make sure. The pump in this kit is Walbro F20000169. It is the High Pressure version of the 255lph series pumps and flows ~60GPH (~255lph) @ 43.5PSI. Basically the same pump as the universal & Mustang pumps but configured to drop in a GM tank. I'm using it on my 414CI small block running ~500BHP and a ~200HP wet nitrous. Before installation I was running a fairly new stock pump and it barely fed the motor only. After installation my high RPM fuel ratio dropped almost 1.5 AFR (richer) so I was able to back off my injector duty cycle. I also noticed that this pump is actually quieter than my stock pump. It is a gearotor design rather than a turbine. It hums rather than whines. The only odd note is with the wiring. The harness provided only adapts to the stock harness in the tank (as opposed to replacing it) so I had to coil the extra wire length around the return tube to give the float ample clearance. One last tip, I installed the inlet strainer horizontally so it lies side to side in the tank. I couldn't find an actual diagram for my car and on the Camaro the angle is such that it would have left the sock sticking above the fuel level at ~1/4 tank and below. This may have been why I was getting some air in my lines. Overall I am very satisfied as long as the performance stays good for a long time. So far so good after ~1000 Miles or so. I did have one snafu. Driving down the road after about a week and the car died. No fuel pressure. Luckily I wasn't far from home so I put the stock pump back in on the side of the road. Go home and noticed the plug on the pump appeared fully seated but had another "click" to go. Reinstalled and it's been good for another ~5-600 miles. Make sure the harness plug is fully seated in the pump connector so it doesn't wiggle out. Difficult lesson to learn lol. UPDATE 3/2018 Running 3 years now and going strong. Just went to the drags this weekend and it has no problem keeping up with my motor and nitrous shot. This is a great pump/value up to about 700BHP. ...read more

used for Spectra in tank replacement

The pump in my new Spectra tank was DOA. I found this one by reading forums and the like. It comes as a kit with the correct adapter plug included. You can find it cheaper, but I don't know if you get the adapter and filter sock. fit the pump holder just fine.

needs product description photo updated

Summit RacingSummit Racing Verified Purchase

VPN-GCA758-2
Description photo shows a bare wiring pigtail that implies an in tank splice is needed. Nice surprise to see that this kit includes the plug adapter so no in tank wire splice was needed. I used this to fit factory replacement TBI sending unit for '89 K5 Blazer, which I installed in a '77 Blazer to run Sniper EFI. I thought it was strange that a high pressure kit includes non-efi hose clamps, but had some extras that I substituted. Made in USA branding is always a bonus! ...read more
