Fuel tank venting?

I did a quick search and didn't find much, so I'll ask...

What are folks doing for gas tank vent lines? Mine has been disconnected from the evap system for years, terminating with an open tube end near my bell housing.

I drilled a hole in my gas cap just like my dad's '63 B.

I ran a line up and across the front edge of the trunk and then back to the under the left tail light. Probably more than I needed to do.

Jim,

Awesome idea. Nice work too! We use a flexible braided line so it installs in minutes and goes up and then back down the passengers side. This allows it to vent AND just as important- during hard take offs, the fuel that sloshes upwards has to go a long way and then back down and as long as the line is high enough and long enough, it will go back into the tank, not the other half of the line to the ground. Now if you have 385 sries rubber on the rear and limited slip with a 800 BHP Fire breathing monster up front, you may want to extend that line a bit further. :-)

Only 315 rubber and 500 hp so, hopefully, I should be OK

Hopefully. I was just pulling those numbers from thin air. It takes a lot more power than I have to push the fuel up and back out again the way we do it. Your just looks SO nice!

About fuel cells and foam ? Generic relationship ? I'm told the new pump gasolenes really attack cell foams. I wouldn't use "alcohol" foam with gasolene, so what's a good solution. I don't see much benefit of running a fuel cell w/o foam, (bladder even better). Anybody ? Thanks, roverman.

Hey Mike,
If you have the vent line in there anyway why not hook the evap system back up?
It costs nothing for power and gets rid of the gas smell in your garage.
There are lots of flat type evap cans that would mount nicely out of sight in your fenderwell.
Make sure to add a roll over valve no matter what kind of setup you use.
Cause no one likes a car fire.

Cheers
Fred

Fred, evap system was stripped before I got the car 25 yrs ago.
Roll over valve sounds like a good idea at the minimum.

Sounds good, 'cept for the three motorcycles in my garage with the MG. ;)
