My pressure sender is all out of whack. It reads low at high rpms and ok at idle. My guess is something is wrong with the sender.
Whats the easiest way to get at this thing. It looks like its right behind the power steering pump and is a real PITA to get at.
If I can make it to the cummins parts place tonight Im going to buy an OEM replacement since I hear the aftermarkets are junk.
Plan is to take off the inner fender and see if I can reach up in there from the wheel side.

 

I know this is for a VE 12v but hope it helps some...

I was trying from the top and just could not get the electrical connector off...going at it from under the fender would be much easier, IMO.

 

looks like if I take the shock tower off I can get in there. No time to do that today =(
That write-up was pretty helpful.. helps to know what im looking at and that this sensor I got are the right parts.

 

Get a sending unit socket from your local auto parts store. They range from $5-10 and worth every nickel.

I laid on the ground behind the front tire and had my changed in about 15 minutes.
Here is the Cummins item number 3923200 from my notes
