I had an engine built for me by a friend who has PLENTY of experience racing. He recommended that I change over my main fuel line to 1/2 inch. I found some aluminum fuel line that would work great, but I don’t know if I have to switch over my sending unit too. My sending unit is only 3/8. Why do...
1988 Monte Carlo LS 4.3L
Does anyone know how long the rear steel line is that goes from the rubber line (that comes off the fuel pump) & goes to the fuel filter on the frame in front of the passenger wheel??
I tried to put rubber line in...wouldn't start.
Then tried a 18" steel line repair kit...
