94yotacrawler

I have a 94 Toyota pickup that I bought as a frame and body, I decided to do an sas on it and make a new crawling rig. My issue is that I picked up a fuel cell for dirt cheap and can't figure out which in line fuel pump to go with. I doubt I am gonna find exactly what I need in an after market fuel pump, so I know I am more than likely going to need a regulator as well, which brand/model do y'all suggest? I know stock fuel pumps run about 27-31 psi and 45 gph, but can't find one to meet both requirements. Any help is appreciated. Also the frame started out as a 2wd and obviously with the sas has been converted to a 4wd, i in the market for an after market cross member, what do y'all suggest? I've researched a bunch of them and although I like the case to crossmember mounting of the front range off road it is a weld in case for attaching it to the frame, I'm not keen on this b/c I've heard it's a pain in the a**, but could be my best/only option. Thanks again
