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

Take a multimeter and check for 12V on the hot wire to the coil with the ignition in the on position. It'll be a spade type connector.

There are a couple of ways to check for spark. Some might have better ideas. I pull the plug and ground the threads and watch it jump the plug gap or just pull the wire and slide a small diameter phillips screwdriver in the connector and create a small gap between the metal shaft and a grounded part of the car and watch it arc. Either way be careful not to get zapped.

You'll need a partner to turn it over while you check for spark.
