Fuel Tank Crud? Redoing Fuel Lines, Etc. Options

[kenshapiro2002]

So, in my continuing fuel starvation saga (another thread), I'm almost ready to rebuild the webers. Rode her hard again yesterday, and she ran pretty nicely for awhile and eventually started to starve very hard at really hard throttle. Took a very good look in the tank, and the walls look pristine, but in the circular baffle area where the sock is, there were many very tiny pieces of black crud, and the sock, though very hard to see well, looked pretty dark too.

Opinions?

Also, I'm thinking that since my fuel filter was pretty clean, that the sock might be my real problem...should take care of that before making the carbs clean and possibly getting more crap in them.

If I do pull the tank and replace the sock, shouldn't I replace the fuel line back to the engine? Any threads on that? Can I just hook a new line up to the old and pull it through?

Thanks in advance,
Ken

Explain this "starvation" you have. Does it just bog down or do you get pops out of the carb too. No lean pops and just bogging means too much fuel or ignition issues.

Starvation with carbs happens when the fuel supply can't fill the float bowl as fast as it's used. You suck down the float bowl and your mains run lean. You then get a bunch of pops and snaps from the carbs. The engine then usually dies because the idle jets get their fuel from the main fuel wells and those are too low already. You then can't start your car until the fuel system fills the float bowls up again.

Pull out one of your ETs and let us know what main and ac jet your running along with what ET you have. They are easy to remove. All you need is a standard screwdriver. Be careful when you reinstall it. Be gentle and don't cross thread it.

I'm trying to help you here but you haven't answered this question from your other thread. There seems to be a few threads of yours on this same issue. It would be a bummer if you go through the work of changing the sock and that wasn't your issue. Starvation usually happens after a hard acceleration in one of the higher gears. In another thread you said it happens more often in first gear which has me wondering if it truely is a fuel starvation issue. It would help if you explained what happens.

Either way if your sock is clobbered change it. You can even remove and clean it if it's in one piece.

Main= 115
AC Jet = 200
ET = F11

Looked at all pieces with a jeweler's loop and they look spotless.
