I've been thinking about this, especially for those of us who run other fuels than straight road diesel, and it sure seems like it could make a lot of sense.

You can't even find a suction lift pump for a Cummins truck anymore, and all the OEMs gave up using suction lift pumps long ago, so what about the viability of either bypassing the suction lift pump on our cars, or simply adding a pressure fuel pump (ideally in the tank) to help things?

This could also have the benefit of making it feasible to add better fuel filtration (perhaps a filter or two mounted in the trunk?).

I assume that the Shut Off Valve can't be bypassed without pissing off the computer, and I don't know whether the SOV would like having positive pressure applied to it.

My inclination would be to simply have an electric pump help the suction lift pump and leave everything else alone. The question then becomes, what flow rate and pressure should said pump output?

Thoughts?
