EFI return line

EFIMAV · 2009-09-05, 22:52

OK, anyone out there using the gas fume evacuation aparatus (thing on top of the gas tank) as their return line for EFI? If so, has it worked well? Any drawbacks?

You have to gut the valve.Then it workes fine.

In a post a couple of spots below I asked about the rockauto 76-77 gas tank fitting my 74. It sounds like this will fit with longer strap bolts? I want to be sure it is the same length and width as my exhaust is designed to fit around the original 74 tank. Depth wouldn't be a big deal. Why the longer bolts?

you still running yours without problems?

Dont have EFI on mine.Did a few other cars though, gutting the vapor valve and useing a good band clamp on the fuel hose seems to do the trick.One guy drag races his 69 nova regularly that I did this for about 7 yrs ago.No problems yet.The other 3... 2 69 mustangs and a 73 Dodge dart are still going fine as well but,they are just cruisers.

OK, mavman, did it require a different gas cap? Also, do you know the capacity for a 74 fuel tank?

Mavman72 · 2009-09-06, 10:04

You will need a vented cap.I believe its 16 gallon,at least the bigger tank is 19(76/77). if I remeber correctly.
