Hi,

I have not messed with a whole lot of p-pumps, other than turning the smoke screw. A guy told me you could put in a thing called a "rack plug" in the front of the pump and pick up 40 horsepower. Just wondering if you all have ever heard of that.

 

yeah do a search for a thread called nice rack i can't remember if it was this forum or not but i know there is a link to it somewhere

 

"nice rack" tread is on the cumminsfourm.com

i tried it, it fuels harder,,,

but u do need to work with your plate and afc before it'll make any difference.

 

The Bosch PN#1413462095

thats the part number for the rack plug you are looking for

 

Can't you just put a washer in front of the plug?
