Have parts and OEM manual, but OEM manual only says figure numbers.... no oem part numbers. the parts came, put they only have OEM numbers and no figure numbers. Currently looking at 07/03 OEM manual for Hy-line & Ultima rotary Lobe pumps that has a list of parts with figure numbers and kit numbers ( letters) but again no part numbers....
I think these fellows should be able to assist you.

HyLine and Ultima Lobe Pumps 52Pages
SOURCE: no power to fuel pump
Did you replace the fuse and the wires appropiately ? Is the shutoff valve button pressed down ? If it's up, then the shutoff (inertia switch) will not let fuel go through the sytem. If the fuel pump is new, then it has to work. Especially if it is an OEM replacement.

A bad check valve in the fuel pump assembly will do that, but shouldn't if you replaced the whole assembly. If you replaced only the pump itself, they may be right. The other possibility is that the fuel pressure regulator is bleeding off the pressure.
