p-80 shuts down at high rpms. why?
 

trying to get facet 2300 ready for my maiden flight, i have a P-80 in it, start up is fine and run up is fine, problem is,,,,,,

when i get to about 110 rpm's the motor shuts off,, gsu reads "fuel failure" i have made sure all fuel fittings are tight, and there are NO bubbles in the fuel lines

pump voltage reads aprox. 2.68 to 2.75 when it shuts down.

i have adjusted pump voltage a few times and seems i still have the same problem,

WHAT AM I MISSING??????????

bad pump?
not enough voltage?
fuel supply problem?

thanks

Check your fuel filter between the pump and the electronic valve.

Also check our upper tank clunk and the condition of the hoses and other tank? What do you have for a clunk in the upper tank? Kelly

i think we have found the problem, fuel pump went bad, to get fuel to flow out of the pump on start up, the voltage has to be set at .350 and it barely flows at that setting,

so a new pump is on order
then we try again
