Yes, what years or engine serial numbers are affected and where is the "53" cast into the block?

I just replaced my APPS and it would jerk like the truck was missing every now and then. Sometimes it would hesitate and then take off when pressing the accelerator pedal also like was surging if you could describe it as that. Are you talking about running at constant speed and the the truck starts to surge without giving it any fuel?

I carry extra fuses, wire, multi-meter, and wiring diagrams for those roadside emergency repairs.

Where do you get the outwears from? Or did I miss it in the post above?

Have you replaced the Apps? 70 mph maybe the position the where the contacts are wearing on your Apss since that maybe the area that sees the most use and wear.

My Apps just died with 97,000 miles on it. I will be giving Timbo a call.

Is this a common problem? Do I need to check my VP pump mounting hardware if it has never been apart?

The ground is just as important as the power wire. It seems like everyone concentrates on the positive when troubleshooting. Also, check for high resistance through all the connections.

I thought FleetGuard filters were made in Cookeville, TN.

Good info! I think I'll do this upgrade when I do my injector install.
