Never changed that filter, but it has a Holley Fuel pump, and 1 of those class filters right before the fuel lines goes to the Carb. So, it's getting plenty of gas. It's always full. Just when the car heats up to normal temp. It runs like a tired dog. It will only do 10-15 mph. Any type of help to point me in the direction would be, well appreciated, and thank you. The Car has custom exhaust, no Cat, straight pipes to each manifold, with flow master muffler.
[Problem really didn't start until, my step dad let a community patient "Methane Head", install 2 new lifters on the passenger side head, while i was at work. 2 weeks after that the car started cutting off and bogging out. I looked under the hood not 1 intake bolt was tighten and you could see where water was running down the front of the engine. I replaced the intake gasket and tighten it back down propertly, but the car stopped cutting off, but didn't stop bogging down.]
