I don't know what "bump" means in this context. But yes -it will work if mounted as close to the tank as possible. GM 6.2s and early 6.5s have the same model injection pumps as the Ford 6.9s and IDI 7.3s (DB2 Stanadyne/Roosamaster). The DB2 can be run with no fuel pump at all since it has its own but that makes filter bleeding very difficult. Doesn't require any pressure. Just don't want to give it too much (over 8 PSI) or it might make the timing advance when you don't want it to. Timing advance works off of fuel pressure.
