OPS Location Fishy
 

have had a lot of fun with this engine---NOT!! I've already learned a lot about the workings of it, Thanks to Diesel Bombers ( you guys & gals are great). Where is the OPS located on a "97" 6.5? I feel silly asking but not looking forward to crawling around under it here in Maine. Ground is cold and wet. Have no garage. Truck has been running like maybe that's the problem, no codes, its either that or IP. No fuel sometime from LP. Can hear it run on start but also can hear it cut out. Supposed to run all the time right? Yesterday open tee valve --nothing. It is new one.https://www.dieselbombers.com/images/smilies/tease1.gif

the ops is behind the fuel filter to the right of the head.

Thanks for reply ebarresi5894's I looked in there can't see it, am I going to have to pull intake?

no, if you move you fuel filter housing and the 4 wire connectors away you should be able to see it. it is kind of hidden but i used a long extension and it took me a toal of about 15mins.

you need a 15mm deep socket, a screwdriver, a extension and a oil sensor socket

on 97 it is in the valley to right fuel houesing just remember yo want replace it with ACDeloc only

Thanks guys will do. Truck is running good when cold but soon as heats up starts surging and lose LP just thought OPS was simple fix. Hope so. If not need to diagnose wiring.
