Anyone have any luck with replacing the vent hose that connects from the vent port at the top of the gas tank to the filler neck?

 

Mine was cut and plugged off which prevented fuel from entering the tank at normal pump speed. I replaced it but the port seems to be an odd size (7/16"). Cant get a 3/8" hose on and a 1/2" leaks.

 

This is on a 78 wagon.

buy 7/16 hose, sorry to be so obvious.I had a spool of 7/16 and that's the only time i've ever used it.

I agree with you there but I've checked the auto parts and hardware stores and can't seem to find 7/16 tubing in fuel line or vinyl. any ideas?

If you find 3/8 vinyl, it can be heat formed to surprising dimensions. A standard size fired case from any rifle like a 22-250, .243, .308, 30-06, etc. works great as a forming shaft. This goes without saying, but since you never know who will read this, DO NOT use a loaded round! Any spent case with the .473 case head will work. Heat the vinyl tubing till it is fairly soft and slide it up the tapered case. Then cool it in cold water. The vinyl will take this size permanently now. It's that easy. This should provide a snug fit for a 7/16" fitting.

Try a local big rig shop,an online subaru dealer,or
