Fuel tank vent puking gas !!

i found this on weldons site

10. Does my fuel tank need to be vented?
Yes, the fuel tank or cell requires venting to the outside of the vehicle. Do not use a vented gas cap in lieu of a true tank or cell vent

Very true. Too small of a vent, especially for an engine that can consume a LOT of fuel quickly can result in either the pump "stalling" out and cavitating from vacuum in the tank or you can actually start collapsing the tank!

I liked Blown353's idea so much I made one. It's not hidden behind the bumper, but instead in the trunk.

Here's the basic idea


Welded up a small tank. It's a frankentank made from lesser failed projects.


Fabbed up a quick mounting bracket


I don't know if this is the best place to mount it, but it doesn't look bad in my opinion.






From under the car. The fuel hose fits perfect between the ribs of the trunk and tank.


Seems to be working great so far and no burps or fumes.
