i have a 97 z28 when i fill it up with gas it marks past the f mark but then it doesn't start to mark right until you drive about 150 miles it marks a little over 1/2 tank. what can i do to fix this problem. it doesn't move to the f or 3/4 mark it jumps straight to the half mark after you drive it awhile
