Where is ofr draw located? Also my gas gage goes up and down randomly. Could that be related. We have already replaced the relay. Thank you!

It could aslos be your oil sending unit as that keeps the pump running while the car is running. The ground on tank shold be attached to a good clean ssurface, not rusty etc.
