Aux Fuel Tank Fill Tube, No Vent Tube???

[BronCowie]

'Just curious how many years the EB came with the aux tank fill tube with no vent tube. My '69 didn't have one and am looking forward to putting this simple upgrade in. What a PITA to fill in the past. %)

Wish I would have known you needed one. I removed my aux tank and won't be putting it back in.

I remember now you saying you were taking it out for good... dang it!

15 years ago I bought an auxillary fuel tank from Toms. It came with a filler tube with no vent. I had to add the vent myself. Maybe your tank was an add on also.

I See why that alot of folfs complain about how long it took to fill their aux. tank.

Somebody here knows the scoop. I don't, but here's my guess. The vent tubes weren't added until the EPA forced gas stations to put those spring loaded seals on their gas pump nozzles. So EBs earlier than ~'71 didn't have them. ?:?

Bump...

So if I posed this question on the "Guess This Part Game" thread, I'd have an answer in no-time.

Here it is, one last attempt.

What year did Ford introduce the vent tube on the aux fuel tank fill tube? ?:?

I guess ahh '73 ..............thingy (oil embargo)

My guess is 70 or 71 since the EPA was formed in Dec 1970. Vapor canister started then too

I thought it was early early(charcoal canister) Just behind the dr.seat?

Don't know the answer but my 68 main tank has one but the aux just has a nipple up near the top of the filler for a run of fuel line that I can't for the life of me get back on without kinking the hose. The nipple on the tank looks a little like an after thought as well. Now that I see this thread maybe it's a PO add on?
