Is there an alternative solution to using my Cobra fuel hat/sending unit? I want to sell it to recoup some dough. I know the Mach 1 unit will work, are there any others? Is it the connector that keeps us from using let's say a 99-04 Gt fuel hat and sending unit? I'm gonna use external pumps with a sumped Glenns tank and all I need is a way to read fuel level.
