How much pressure does the return line have on it for a 85-92 TPI system?
I am converting a older vette to a TPI system and have one last fuel line to connect and thats the return line. My local store doesnt have 1/4 inch fuel injection hose, but does have regular 1/4 fuel line. Will normal fuel line work for the return? Is the return under much pressure?
The return is under very little pressure. It should be a clear run all the way back to the tank with no obstructions. Any hose of the right ID and rated for fuel will do.
