I'm thinking that using the 15"x8" cross mat, positioned so that the mat lays over the driveshaft hump and into both sides of the fuel sump, hooked to an additional intank pump which will pump a feed line back to the stock unit and dump fuel into the plastic "pickup can" may be the trick. The whole goal is just to keep that can full of fuel.
If it works it will be huge. I plan on testing this. I'd love any insight you have.
