not that difficult a task to switch the tunnel lines out. imho, with carbs you don't need to bother with the return line if you don't want to. there's a recent thread re capping the return line at the tank. as your tank was crappy i'd invest in 10 feet of new fuel line and shouldered clamps to plumb the carbs. of course, toss the old filter. flush your pump (you bought a rotary iirc. if not now is the time). start new and clean, front to back. i think your carb woes were a direct result of the fouled tank and screen/sock. Well currently I have a Facet pump under the car where the fuel lines exit tunnel. I have an in-line fuel filter just upstream of pump. I always figured it was safer to keep pump under car in case of failure rather than engine compartment but it makes changing that filter a real pain. Anyone ever use a small valve upstream of filter for easy replacement? I was considering just capping return line where it leaves tank. Do you know the size/thread of that cap needed? Also, do you think I should upgrade to a Carter rotary over my Facet? That Facet has made noise at times but I think it may be due to the junk in tank. |

How do I know which line I need? 8mm or 9.5mm? Do I measure that and how do I measure it? Also, do I need that adapter? Cant figure out what that is for.

I spoke with Chris at Tangerine and I think I got everything I need. ONe thing I wasnt sure of is whether I need to put a sealant back into that tank or not after cleaning?

Well after pulling the tank and cleaning all that gunk out of there and then replacing the fuel lines with ss lines from Tangerine I am back running again. I still cannot believe how much junk was in the system.
Can someone explain how all that got in there? Is that just rust and stuff from bad gas from so many years or what? I was amazed at how clean it came out too. I would think if it was rust there would be pits but it looks great! |

gas is transfered from the refining process to a holding tank, then to a tanker truck, them to the in ground tanks at the gas station, then to your car via an open cap. Lots of opportunity for dirt and debris to enter system. Besides, your tank is now 40 years old and has seen a lot gas go thru it.

Well there were huge chunks of stuff coming out. Is that a result of the chemical break down of the gas?

Probably not. Gas turns to a jellied vanish substance. Probably rust flaking.
