I have been able to get the 3/8 fuel line disconnected with no problem but the return line will not come loose. What do I need to get this line loose? Do I need a 5/16 or 1/4 tool maybe? Please help, I'm trying to get this loose so i can do a head and cam swap. Thanks ahead of time....

 

Are you talking about the EVAP line? If so you need to squeeze the taller sides of the connector, then pull back, and itll come right off.

 

Not sure, it is the smaller line near the 3/8 line that connects to the fuel rail.

 

Hey, thanks that did it. I squeezed the plastic in and pulled and it came right apart. I appreciate it.

 

Glad I could help... good luck with the H/C install!
