Default suspect mpg readout

My 84 always gets the same readout for mpg when its driven. 9.6. When Im stopped it goes to 0. I have a xram manifold and a 85 fuel pump. Are these guages realiable?

They never were worth much, but yours is much worse than most. It must be that funky intake manifold.

RACE ON!!!

CFI is right, those things are off a bit. Yours is screwed up and might be out of calibration.
