the cover you had to remove to get to your fuel plate is called the AFC ( air fuel control)

that foot moves foward and back as boost goes up and down. there is a good write up in the aftermarket section on how to mod it

I think there a little on the big side for what your looking to do ... you could use them if you like but I would try the other things listed above first before spending any money on marine injectors.

the SDX injectors that I recomended above would work much better than the 370's and are about the same price.

Thats what this site is all about, Members helping Members If you have a question, You will find the answer here. Im running a set of the Indutrial Injection honed 50 hp injectors and they flow plenty of fuel, not alot of smoke and slightly higher EGT's. Ive been happy with them while towing and playing

ive ran 370 marine injectors in both of my cummins 12 valves and have had no real problems out of them, they give a noticable power gain over the stock injectors but they do give a hazey idle depending on how youve got your pump set ect.

ive never had no problems out of them,but its all preference.
