    Rated 5 out of 5 by from Looks and works great. This is a great addition to my GoStreet EFI. The only drawback is making the EFI hose connections are extremely hard. I was not able to get the filly seated to the thin metal ring(which is also really easy to pop loose)

    Rated 5 out of 5 by from Excellent product. Very little noise. I researched this before purchasing. Excellent product. Vey little noise and I am real happy with the product. Fits nice in the engine bay. I had to make a bracket for it to mount to but no problems at all. Buy from Jegs, they are the best

    Rated 5 out of 5 by from Great product I just hooked up the fitech system and the kit works really well. The fuel kit is a little noisy but the radio drowns it out. It uses the stock fuel pump and increases the pressure to fit the fuel injection system. Thanks y'all!

    Rated 5 out of 5 by from Fuel injection on a 455 Oldsmobile This product is surprisingly simple to install. Tech support line was responsive and in America, so answers were direct and clear.

    Rated 5 out of 5 by from Excellent unit Installed this pump unit to use in conjunction with a Holley Sniper EFI system. Install was straight forward. No issues other than the kit not including enough hose clamps. I ended up using Russell reusable AN fittings so it was not a huge issue, but it may matter to someone who plans on using the supplied hoses and clamps. This unit was mounted on my firewall behind the passenger side wheel fell. It is not the quietest pump ever but it is not too loud to really matter. The sound of the exhaust is loud enough drown out the noise. Couple that with the tunes blasting and you'll never hear it. The unit DOES run pretty hot but it has not shown to be a problem. From idle to WOT, there has been no issues whatsoever. If you're going EFI, this is definitely the way to go. No regrets with this unit.

    can you run leaded fuel with this system

    Asked by: jamg59
    Yes, it is the O2 sensors in an EFI system that do not work well with leaded fuel.

    What thread size is the vent? I need it to be a 45 degree angle for routing. Can you help? Thanks

    Asked by: 67RestoStang
    The vent is a 3/8" hose barb, you could change it to a 45 degree hose barb fitting by taking the top off and changing out the straight fitting.

    I have a 90 cadillac 350 v8 with throttle body injection, factory. can I use the original fuel pump? It is a tank mounted unit for the tbi, also will the oxygen sensor I now use work? My computer is fried and the injectors tired, so i thought upgrade.

    Asked by: rogerschadwick
    You will need to use a high pressure fuel system for the FiTech injection kit. This fuel control is a perfect match.
