I need help with one of my models i am returnig to after setting it down for a time due to bugs in the game. the bugs are now solved, so the model works again, but i have encountered another issue, and im not sure how to address the issue other than using the 'infinite fuel' cheat full time.

the issue seems to be inadequate amounts of fuel being fed into the fast enough to properly power the engine. I have positive fuel flow, and there is plenty of it, but the flow rate is only 1 - 2, where for proper operation it should be around 5 or 6+. i have tried adding additional pumps to try and move the fuel faster, but instead of increasing the flow, it seems to have done the exact opposite. the main culprit seems to be the large pumps i am using to feed the engine, even though they are at full pumpoing power, they are only pumping a max of 5, where my model needs at least 10 or 12 (2x large engine + 1 small engine). i am not sure how to increase the amount of fuel thats making it's way to the engine. do i use additional fuel lines coming from the fuel tank and feed them to the 1st pump in the line to the engine? if not that, what then?

*notes: model is very much a W.I.P. not everything works or is finished being installed. the weather monitoring, GPS auto pilot and video transmit/receive being examples. steering, stabilizers and engines all work. just remember to activate the mags (6 key) on the helicopter before leaving port. although the copter is technically 'tied' down, it will still move around the flight deck unless you activate the mags on the copter.
