Thread: Fuel vent

Ken--refresh us on what the engine is, what your using for intake( carb/ efi ) and possibly just exactly what fuel pump you have plus how are you using this car?

I've went back and read thru many of your posts--------------I would suggest that you begin being a little more up front on exactly what you have and be curtious and answer some questions that have been asked of you plus stop starting a new subject every time------

For starters--------you can probably slove all your fuel issues by installing a mechanical pump on the BBC--------and removing the electric pump-its pretty obvious that you are most likely running too high of a fuel pressure that the needle/seats won't control resulting in engine flooding, washing down cylinders
etc------this often will result with raw gas getting into the hot exhaust system on shut down and will cause GASSY smell/ fumes for hours in an enclosed space or even nearby while outside-------

I also must mention that these conditions often result in a fire that grows into an unstoppable mess because the electric pump may not be wired with proper safety methods and the pump continues until tank is empty-------and it may be able to empty the tank before the fire department arrives

My car is a 68 chevelle ss with a 489 stroker 9.7to1 compression , it Dyno 649 hp an 591 tq , it's got aliumum AFR heads ,all callies bottom, it has a magna fuel electric fuel pump with 1/2 gas line front to back and a aero fuel pressure gage , the block was a 454 1991 4 bolt can't run manual fuel pump , it has a 950 quick fuel carb with 84 in front and 94 in back , timing is locked dn on 40 degrees that's were it made its most power at , iam having problems with fuel pressure I can set gage at 6 lbs drive it to town it might be on 0 but still be running ok or it might be on 10 and the float bowls fluctuate, took plugs out tonight and they were wet they are 3924 autolite, also can feel a little quiver miss when after it pretty hard , smells like raw gas in garage , I hope I have covered everything,

I have a Professional Products regulator on mine it did the same thing as yours (about 4 years old), bought their rebuild kit and it fixed it.

According to Magnafuel's website, their lowest pressure carburetor pump is 18#, and requires a return line?
