I've decided that since I'm getting the car painted I might as well pull the tank and fresh air box and do it right. I do have some fuel in the tank and just need something to plug the fittings on the bottom so I don't end up with a lake of fire in the garage.
I'm going to replace the lines from the tank to the ones that run through the tunnel but can't remember which size. I seem to remember either 12mm or 5/16. I am running carbs so the high pressure FI lines aren't needed. |

Good luck, I hope all is well with your project. Steve |

alan, 5/16 (8mm) is what i used. i broke down and bought a 25' box of Gates fi hose. i can use it for FI or carbs. per foot cost was the same as standard carb hose since i bought in *bulk*. next i'm going to put in one of chris' stainless lines so i can forget the center tunnel hassle forever. do you have to run a return line with your 6 fuel pump?

5/16" is too big. 7mm is correct. The larger of the 2 lines is 9mm, and is the supply line. The smaller is 7mm and is the return. Neither is a "pressure " line in a 1974 chassis, as the pump was originally mounted in the rear. While FI hose is always desirable, even more desirable is the correct diameter! Were I choosing to eliminate one line, I would choose the smaller one, especially since the larger one has a debris screen ("sock") installed in the tank. So what you need is 9mm hose. Odds are the 8mm won't fit. The Cap'n

The actual fitting size coming out of my tank (72) is 8 and 10 mm. It's sitting on my bench right now.
