72 Chevy Truck, BB 454, tank is behind the seat I am replacing my mechanical fuel pump with an Edelbrock electric fuel pump part # 1791. The Edelbrock technician said to mount the new pump below the tank on or near the frame...no problem. However, when I removed my mechanical fuel pump I noticed that there were two fuel lines...a 3/8" line and a 1/4" line. The Edelbrock tech said the 3/8" line is the main fuel line and that it should go/hook up to the electric fuel pump….NO PROBLEM! But what do I do with that 1/4" line…it runs from the tank to the engine compartment…I was told it was a return line for the old mechanical fuel pump….I have a bolt with a hose clamp on the end of it. Can I just remove this line altogether???
