C.P.S. Offers 2 Facet elec. fuel pumps Model # 8501 rated at 2.5-4.5 psi
and model # 8502 rated at 4-6 psi Wich one is the correct one to use on a Rotax 912 80 hp? Also is the correct place to mount the pump between the gasolator and the engine? With the return line going back to the gasolator.

Thank's Dutch.
