Post subject:  Gas Tank Vent Tube

What size, outside diameter is the filler vent tube for the gas tank in my 63 Valiant. PO decided he didn't want it, but I sure do. Can't seem to locate one locally so I think I will make my own.

Should be able to bend-up your own out of steel brake line tubing. Pretty sure it's 1/4", but it could be 5/16". Make sure to follow the factory routing (out from the boot in the trunk floor, zagging steeply upwards along the left rear wheelwell, making a fairly tight U-turn and then back down along the wheelwell over to the fitting at the outboard end of the filler pipe).

Did they design it that way to keep you from pouring gas all over the top of your tank if you screwed up refilling? Thanks for the help.

Mainly to prevent a siphon effect.

5/16 is the main fuel line size.
On the non-emission setup the vent tube is much smaller than
the main fuel line

BYB - (to the garage with the calipers ....)


The vent line measures 1/4 inch OD
