I can't say how reliable it would be though... One interesting setup I saw a long time ago, was a guy running his fuel at 100 psi!!!!! He was using several stock nissan fuel pumps to supply the extra fuel. (two pumps in series or parallel will supply twice the fuel, or be under half the stress at the same flow)
thats insane fuel pressure im at 44psi at full throttle and about 34 at idle using a mercedes fuel pump
