I have a 69 Riviera I'm insterest in installing the Holley sniper EFI, my question is with the 69 already having an elec in tank fuel pump that I need to replace with a 60psi unit, I need a fuel return line I noticed in the trunk there is metal tubing in the shape of a loop. Can I cut this metal tubing and connect my fuel return line to it. Has anyone installed a EFI on a 69 Riviera
Jerry you might have some luck joining a Facebook riviera site for year of your car, and asking this question. Seems like Lots of Riv guys hanging out there.
Jerry that tube in the trunk that loops around and goes out the passenger side rear wheel well is your tank vent tube DON'T cut that. I added a return line to my 69 Riv, it wasn't that hard at all really. You do have to drop the tank as there's only one spot you can put the bulkhead fitting on the tank. I just used a coil of aluminum 3/8" tubing and hand bent it to follow beside the feed line up to the rear wheel well then went to rubber from there to the tank. I also went to braided rubber line from the front passenger wheel well up to the top of the inner fender where my pressure regulator is mounted. If you'd like some pics let me know I'll post them. As for EFI can't help you there, sorry lol.
Jerry, I am installing sniper Efi, on my 69 cat as well. You can get the throttle body that doesn’t require a return line.
