Anyone know off hand, how the original fuel line was run in a 1970 Buick Riviera???
The original fuel line was gone, I guess they removed it when they changed the stock mechanical fuel pump out for a electric fuel pump in the tank. They had run the new rubber fuel line down the passenger side of the car, right over the top of the exhaust. The rubber line had 3 spots where it had melted because of being over the exhaust. Plus on top of that it was run in the top of the passenger side rear wheel well. so if they would have hit any hard dips or bumps the wheel would have come up and hit the fuel line probably pulling it out, or at least tearing it up. It has a X type frame under the car.
I was thinking of going thru the frame, but then thought I better not, because the drive line runs thru the center of the X in the frame. I also need to know what wire in the tank works the fuel gauge in the dash, is it a ground or a power wire??? Since they rewired the tank for the electric pump. I am gonna go back to the original float that was in the tank because the one that's in there now does not sit right to seal the pump in. It was not even locked in like it should have been to keep the tank from over flowing or leaking fuel out the top. So I am gonna run a inline electric holley fuel pump, out side the tank. Not sure if I should run the Blue or Red Holley pump though this is a 455 motor and I want to have plenty of fuel. Then I'll run a fuel regulator to keep the pressure down where it should be. I'll be running Edelbrock heads and intake with a 750 or 800 holley carb and a nice lopy street cam. What size fuel line do you guys think I should run from the tank up, 3/8 ??? Thanks for your help or input. Kurt
