HELP! non - emissions fuel tank vent (check valve) - any pics or advice?
 

I realized my fuel tank is not vented properly, so vacuum builds up as fuel is sucked out. I need a solution that is safe (rollover protected) and ideally easy to install. Emissions considerations are a secondary issue for me. Having done much searching, I haven't found any photos or details of specific part numbers, which would be very helpful. I also searched PP for a new fuel tank vent, check valve, etc, to no avail. I've also been to mcmaster.com, though their selection is endless and without seeing the specific setup, I suspect it would be an iterative process to find the right solution.

Ideal would be a barbed T that would be inline OR maybe tee'd to the 12mm ID (grey-braided) vent line shown in the picture below.

Other solutions, pictures, suggestions would be much appreciated!! There seem to be a lot of race-specific setups that use AN lines from fuel cells, but my Porsche tank is not outfitted with AN fittings.

Thanks a bunch for the help!

I just bought a good PVC vavle and used FI rubber hoses. I routed the hoses to the fender well and ziptied the check to the chassis. You can get more expensive check valves from Pegasus. Good luck.

I used a one-way valve from McMaster car. It cost about $2. It has barbed hose ends and fits in-line with my vapor line going to the rear of the car. this allows for equal pressure but no liquid release.

Great idea! I'll explore.

Do you have any way to look up the part #?

Thanks for your help!
