The PO used the existing hard vent line to vent just the main tank and ran a separate 7/16” hose from Aux tank to a “T” fitting into the small length of hose just below fuel filler. I suppose this was to allow for faster fill ups. I’m thinking of going back to a single line branching to each tank like factory. Any find this mod beneficial?
Thanks
Mike,
Search for Recommending High T.
It is the result of a CFD analysis that I did years ago.
Matt
I should have known. My PO has done some pretty good mods. This statement from your post clears it up. “ because the rear (main) tank actually fills first (with little regard to vehicle trim (ride height front to back), it will always flood the vent line if given the opportunity”.
I’ll be replacing the High T.
Thanks
