i was only going to change pump because my intank pump has shit itself. i am eyeing off a new set of injectors though.

The regulator sets the system pressure (unless something down stream of the regulator is restricting flow).

OK looks like i would be ok to swap out the pump as there is no other restrictions downstream. I also just found out that the walbro 460 pump flows 390lpm at 73psi which is pretty much the same operating pressure as the bosch 044 but with 90 more LPM i should be fine.

FYI my engine is running seimens 60lb injectors and i might be upgrading them soon as well.

Can’t wait to say goodbye to my noisy 044!!!

Thanks guys I’m going to check every inch of my leads. I will even run some extra insulation around all the leads
