is the IP dead?

[treemonkey]

Hi Guys, still having trouble with power loss issues with my 97 K3500 dually, truck starts and runs fine for up to 5 miles then gives a little cough and loses power,SES light comes on. If I stop then restart the SES light stays on but problem eases for a mile or 2 then returns. Replaced fuel, air and oil filters about 2 months ago. Recently fitted pmdcable.com new pmd, extension cable and heat sink. Had fault codes read and only code stored was P0251 Injection Pump Cam System. Before code reading I had been wondering about uprating lift pump with a walbro and prefilter but don't want to waste money on new LP if the IP is the problem!
TIA

sounds like it could be a clogged tank sock

I've got the pick up out of the tank and the filter sock looks pretty filthy, what do you guys use to clean it, or should I just replace it?

replace it. Carefully inspect the tube as well. They tend to deteriorate where it bend into the mounting plate. I usually fill a tub with water, plug one end of the pu tube and put shop air in the other and submerge it to look for leaks. It's a common fail point.

I think leroy sells an up for grade kit for that. I have not used it but others have had good results.

IIRC Leroy's kit is only for the sending unit. It reuses your existing PU.
