    Twin Fuel Tank Idea

    I know this has been discussed previously, but I couldn’t find the thread. The idea of having 2 tanks that are both feeding the motor, to eliminate the need for a tank switch, has been knocking around my melon for quite some time and I think I came up with a solution. I drew a quick diagram...

    four gas analysis

    Fuel Tank Delete

    I've got an 85 C20. I've got duel fuel tanks and I want to get rid of them and put a transfer tank on the flatbed as my only fuel point. Has anyone ever done this? Any pointers? This is my first old square body that I've really worked on. Thanks alot!

    Engine cuts off when I press on the gas pedal

    I have a 78 k10 with a 350. For some reason, when I press on the gas, the engine cuts out. Is this caused by the fuel/air ratio, the choke, or something else?

    350 Cutting out at High Idle?

    Hi, I have a 1976 c10 Scottsdale I've been driving for about 2 years with no issue. However the past few months it will intermittently cut in and out when revved up. It isn't like normal sputtering, imagine someone who has the accelerator down, and releases it, and puts it down again the the...
