May I have gotten a pump that’s to tight and needs a higher voltage less than the. I removed it and installed my original pump back in and normal operation. The Kerostart fuel line also had no movement. I did this several times and was cautious as to not flood my engine. To test this, press the “Run” key several times to check that the pump starts steadily running on different pump rotor positions. The U-accelr1 is for the correct voltage so that the fuel is delivered in a thin fuel stream (a little bit more than just dripping out of the tubing). Now keep in mind the start voltage for the pump prime is. Then I set 1 = U-accelr1setting for the correct fuel flow. I installed it and performed the prime pump procedure. I got the pump from Dreamworks just about a week ago. I decided to buy a new one for my new jets first flight.
