In the electric pump department the Walbro series seems to be doing well. I do a RASP, but several seem to be pretty happy with the Walbro. Several sizes to choose from. Read threads to see what might fit you best.
There are lots of threads on electric lp's.
Gary - K7GLD has done a fair bit of testing of various electric pump configurations. I would at least bounce an idea off him and get his take. He also has put together a bypass valve you install at the VP44 to keep the VP44 input pressure stable and at the pretty correct psi value.
Add a fuel filter / water seperator as you come out of the tank (I use a RACOR 690-T), use at least 3/8" lines through out so you get good volume, go to your pump, go on to your bypass valve (route the excess back to the tank or tank filler vent line) feed the Vp44 and you are in business. OR something like that whatever works for you.
