    EFI Fuel Pump Upgrade

    Website version with assembly pictures at:

    If you have a vehicle that came with some type of EFI then this may only be a slight upgrade, but if you are doing a conversion then this is really the only way to go in my opinion.

    Through looking for part numbers, I found that there are many different height units. It very well may be possible to find a module that fits your tank height with out modification. But I would recommend only using one that has the siphon jet, be sure to check as some don't.

    I have done this to both my '78 Camaro and my '74 K10 Truck. They both work great. Enjoy. Sorry I had to .zip them, it was the only way to fit them on the forum.

    Part 1 Module modification
    Part 2 Tank modification
