carb or injected?

tucker 1955 · May 26, 2019

it is a throttle body. my problem is the moter runs about 15min then blows 20amp fuse

This is the best I have....came out of PCM documentation...doubt there is any significant difference...

I'd be inclined to change the relay....they are known to have finite service lives.....bad contacts = voltage drop = excessive current draw....
