i have a 35' chevy pickup...and i had to drop the origional tank due to the fact it was rusted threw...so i decided to put in a tank i dropped from a 56'. The problem is the origional fuel bowl (gravity powered im told) isn't getting any fuel to the carborator. I have tried numerous fuel pump..but they keep going out on me....anyone have any ideas on how to get my bowl working for me (so far its all original except the gas tank and the spark plugs, wich i replaced last weekend)
