While driving at WOT my injectors are maxing out and finally I end up with fuel starvation. A bit like driving with a clogged fuel filter or running out of gas. So I hooked up a pressure gage in the fuel circuit and guess what, the pressure is dropping steadily with a loss of 30% at wot. That means the fuel pump is not delivering enough flow.

I calculated that at WOT the engine fuel demand shouldn't be far from the 2l/mn the pump is supposed to deliver. Add to that wear, circuit flow resistance etc. and the engine does not get the amount of gas it needs at WOT.

So, I'm going to fit a new fuel filter to make sure that is not the problem, and I'm going to fit a spare Djet pump I have in parallel to keep pressure as it is but increase flow. A bit like the set-up on the 560 that has two pumps in parallel.

I have two questions in case someone knows:

will the electric circuit of the one fuel pump be able to run a second one without burning or blowing the fuse?

What is the flow rate of the stock D-jet fuel filter? Will it act as a blockage?

Thanks!
