Fuel system downgrade

[JoshH]

I am removing my dual stock pumps to install my 10mm (that was supposed to be a 12mm ) Exergy pump by itself. I’m running 2500 uS at 195 MPa right now on my 100% over LMM injectors. Anyone know if this 10mm pump will be able to keep up?

What size injectors?

I think thats the first time Ive read the word "downgrade" in a thread title here? You had me scared for a second, Josh.



As to your question, yeah....need to know injector size too.

Sorry, I thought I put the injector size in the original post. I fixed it now.

No, you won't be able to keep up with a single 10, if it were a 12 I believe it should. Have you checked the pump stampings to make sure it is a 10 not a 12? The first two numbers are the year, the third number designates what size the pump is.

This info is direct from Rob @ Exergy:

EPxx-2xxx = Sportsman
EPxx-0xxx = 10MM
EPxx-1xxx = 12MM
EPxx-3xxx = 14MM

Looks like I’m holding right at 26k psi on 2500 uS pulse width.
