It looks to be electric fuel injected is a (Holly) carbuator & electric fuel pump in the back of car. U know what advice I would *Greatly Appreciate. Thank you.

There are a couple of things, is this fuel injected or carbureted? It makes a difference as to what adjustments to make. If it's' fuel injected your pump may not be putting enough pressure to it. YOu can go to www. Holley. Com and type in your model of fuel injection and they have a booklet to print up for diagnosis. If it's a carb, Holleys have a plug on the side of the float bowl, there is an adjustment for the float just above it, pull theplug and have an assistant turn the key on and see if gas comes out the plug, it should just barely come out for a correct adjustment. Do that on both bowls if they have the plugs and adjusters. They will look like a screw with a nut on it. It would help if you know what it is a carb or juel injection.
