Can i convert the 1/4 return line into the tank into a pressurized return line?
I will have an electric inline pump on the feed line, going to a throttle body injection unit. Withing the TBI unit, is a fuel pressure regulator right before the return line. The return line for stock tbi systems is 5/16ths. I would like to convert my 1/4 return line into a 14psi return line.
Is that line specifically a vent line, or can it be pressurized like I would like to do. Has anybody done this before?
I just bought a new tank and sending unit, i got the sending unit with the return line hopeing to be able to do this. I will be using -6 braided steel for my feed line, and -4 for my return. Wich is 3/4" for -6 and 1/4" for -4. Im pretty sure those correspond.
Any suggestions or hints that anybody could give would be greatly appreciated. Thanks
