Sounds like you need to use an electric pump. Running on a carb with the standard mechanical fuel pump? This would cause that problem. Try buying a regular, universal, electric fuel pump at the parts store for 30 bucks and put it as close to the fuel cell as possible. For best performance, use steel line. Put the filter in front of the pump. It will take a while to prime it but when it fills up, it will work. If that doesn't supply enough fuel you can get a deisel fuel pump and use it together with a regulator. Get the pump used on the 1988 Olds Omega deisel fleet cars. Around 85 bucks.

if you are running a stock fuel sending unit with the holley blue pump the stock "filter sock" is probably just getting sucked into the assembly. OR, the sump end is too close to the bottom of the tank. if the car is fuel injected, it is designed to run on 87-92 oct. so changing the octane outside if that could throw off your fuel/air ratio and cause some vapor lock. Finally, also check and make sure you fuel line up at the engine is not boiling the fuel, sometimes the fuel line/rail will get slightly bent towards the engine and get too hot. hope that helps.

if your cars a race car then you defineatly should know if the fuel filter is in the gas tank because it should be sitting in your back yard because 98 out of a 100 racers will put a fuel cell in a race car instead of the stock fuel tank, and 98% chance there is no filter in the tank cause they didn't build them like that back then

High octane fuel will not make a car run any better if it does not need it. If it did not spark knock on 93 or lower octane, you are wasting a lot of money on nothing.

yes they do we call it a sock. Your fuel problem or the bogging should not be because of octane. Other than the higher octane burns a lot slower than lower octane. Lead helped burn the fuel slower. If you are running higher octane you can increase ign timing for faster off the line acceleration, because of the slower burn. good luck master tech

If you could please,what has been done to the engine,if anything? What kind of racing do you do and where? Is it hot where you run or at high altitude? You could be suffering from vapor lock. Yes there is a sock on the in tank fuel pump . Please more info please?
