I'm going to have my fuel tank dropped for some fuel line mods (ITP in-tank mod) and am toying with doing the harpoon mod (cut the two vent lines with a pvc cutter) so my tank will fill up without all the fuss.
My question is if anybody who has done this already has any problem with the diesel spilling out of the filler neck? Some of the stations I fill up at I will see the fuel froth coming up my filler neck when the pump shuts off with the longer vent lines. I would like to do the mod but not if I will spill diesel out of the filler neck every time I fill up.
