I replaced the old style mechanical pump as recommended by Rotax. I have an electric fuel pump and fuel pressure gauge. I usually take off with the electric pump running in addition to the mechanical pump. When I level off to cruise I turn off the electric pump. My pressure usually is about 4.5 psi. Last week I was flying and noticed the EIS warning light and it identified my fuel pressure to be about 0.9 psi. I quickly turned on the electric pump. The pressure went to about 3.5 psi. I flew back and landed without incident. The engine never faltered. Any suggestion on how to test the mechanical pump? Any suggestion on what the problem might be? I have not had opportunity to remove the cowl to make any visual checks.
