What size fuel line is used to replace the fuel return line with the quick disconnect line past the "T",,, to the frame steel line.

 

Have you guys just swapped out that stock plastic line with the quick disconnect and just use a regular good fuel hose and regular screw hose clamp?

 

Im going to pull that quick connect off to check for air in the return line. It might break or maybe the O ring will be messed up and leak if I reuse it

5/16" should do the trick. I have hose double-clamped over the male part of the quick-connect and have had no issues, even at 45 psi.

Thanks

.375 is 3/8"

The return steel tube was .315 , yeah 5/16 sound right

 

Another question, Is the return line pressurized or have a vacum on it when the truck is off?    I dont have to bleed anything if I remove that return line do I? , Just replace it and go...?

No bleeding necessary. It will push fuel back into the tank as soon as you start the motor
