Re: electrical problems. HELP!!!
It could. It's probably a good idea to replace it anyway. Replace the one on the front of the engine first. You can follow the fuel line from the carb down to it if you can't find it. This one is most likely to cause trouble, as the quadrajets have a bypass built in. It might be a good idea to replace the quadrajet one too while your at it.
With my '70 I only had one fuel filter. The fuel line came straight out of the fuel pump to the carb, then in the little housing where the fuel line connects to the carb is the filter. I just took mine out and put a clear fuel filter there that you can pick up at autozone/kragen/etc.
my 78 sdv has the a similar problem it hesitates when i hit the gas and i have to feather the pedal to get it to stay running but sometimes it stalls altogether backfiring generator light oil light the whole 9 yards i have tried everything from tune up, k&n air filter, and new exaust to get it to breath a little better but nothing has helped so now i beleive it is the accelerator pump on the carb
I just got over a a bad dead spot from a standing start with my Edelbrock 600. Rebuilt the carb and put a new cup on the accelerator pump and now it works fine. Sounds like your pump is the problem to.
