68 Fuel return line
My car does not have one and I want to add a fuel return. Thinking through the possibilities of adding the line along the frame to the tank. How about some ideas from those who have done this with the body on. Rubber hose, braided hose, solid oem style? Looks like the oem style would need a splice. Suggestions are welcome. Thanks

Humm?
No return line.
I guess you realize that the only '68's without a return fuel line were Holley carb equipped engines (427's--either 400/435 HP tripower, or the L88)
U might want to do some research on how your vette was origanaley quipped?

Anyway, now that summer is here I have the problem of fuel heating up and idling rough and a bit difficult to start when hot after sitting for a bit. I liked Lars fuel return solution and that is where I'm headed.
Besides, a PO put a Stingray emblem on it so it's not worth anything any more. :-)

Would not suggest rubber or braded under the body .

If you take a stock return line and split it where it goes thru the cross member next to the frame you can make it work .If you have a flare tool you can get a union at the parts store if not get a male barbed fitting and double clamp both sides .

Definitely do-able...I ran both new lines in two sections, bent them by hand, and spliced them (with fuel line & clamps under the frame) all with the body on ...
Good Luck!

You can also use nylon lines. I think they rent the tool to insert the ends, but I have the tool so I never looked into it. Just press in 2 steel barb splices at each end after you figure the correct length. 3/8" and 5/6" are easy to get, but I couldn't find anyone with the 1/4" line so I used 5/16" for the return. I used the original clamps and bent them so they fit around he larger line.

When I get Corvettes in my shop with the fuel lines looking like this....I just shutter and ask them if they want their car on fire or not.
Rubber hoses hanging down are accessible for something to grab or cut them is NOT wise....and I can tell you that one morning I came into my shop and the gas fumes about knocked me down... I ran and shut the power down in the shop....and FOUND that the car I brought in the day before had this set-up on it and the hoses leaked fuel out on the ground.
SO..do what you want.
