Dual Walbro's in a 1G AWD

[Halon]

I started researching into if there is an amerage issue with running dual pumps off the stock wiring. I believe the MPI fuse is a 20A fuse. On RRE's site they show at 73 psi, the pump is drawing 10.5 amps. Double that for 2 pumps. Now I'm wondering, does that MPI fuse directly feed the fuel pump? If so then at full boost I have a good chance of popping that fuse. But if that fuse is just for the MPI relay, and the fuel pump feed is actually coming through different leads on that relay or something, meaning that 20A fuse isn't in the direct path of the fuel pumps, then I shouldn't have a concern with that 20A fuse.

Anyone who knows a lot more about this then me care to chime in?
