I'm putting a Facet electric fuel pump in my 1987 300D to help move the SVO from my veg tank to the veg filter. The instructions say to put it no further than 12" from the tank, so it will push the fuel rather than pull it. The guy at the auto parts store also warned me about this. The problem is that due to the fuel line-in-hose design of the greasecar system, it's not really feasible to put the pump near the tank. I was planning on putting it in the engine compartment right where the pex line emerges at the bottom of the veg filter apparatus copper coolant winding. This, of course, goes against the advice I've gotten so far, but I can't think of another solution. The pump puts out about 5-7 psi continuously (unregulated). Also, I'm not bypassing the lift pump, so the pressurized fuel will be arriving at the lift pump after going through the veg filter, solenoid, and about 2 feet of hose.

Anyone have good or bad experiences to report with locating an electric pump far away from the fuel tank? Using in conjuction with the lift pump? Am I going to break something?
