so here are the pics of both filler necks.
ones out of the truck, one is still installed, easily removable.
the last one is the diesel rear filler neck for my SRW F350 for comparison.
both will come with the inner tubes.
i will need the outters tho.
my best advice is to somehow, knock out the flap from the gasser necks, and use a knock out kit to enlargen the hole...
or a stepped drill bit.
its up to you if you wanna use these. i have never done this, so im not 100% on the modifications.
