I'd do the cheapest thing first. Get a guage from Summit for less than $20. If its an electric gauge with a sending unit, the sending unit might have chit the bed.

+1

Do you have a gauge on the fuel line or in the car? If not I recommend one for the fuel line if you dont have one. You might be able to get one down the street at on e of the 4 auto part stores right around the corner from you...lol

Mechanical or electric pump?

If electric, where is the pump?

Where is your fuel pump located? Are you using an intank pickup or sump?

What type of pump?

I know I'm asking a lot of questions...but all of these are important.
