It's been a while since my last post. The truck seems to be running well after removing the VORAD control box. The APU has started stumbling at times as if the fuel filter or fuel pick up is getting clogged. I suspect the latter due in part to the trash that can get into the tanks. I believe there are aluminum chips and waste from when the hole was drilled for the fuel pick up during the APU's installation. If a tailing from that got caught in the end of the pick up tube, it could reduce the flow of fuel to the engine enough to starve it under a load. I'll get a PM done on it after I get home as it is in need of one anyway.
I'm heading to Holcomb, KS for my last load this time out. It'll be a relief to finally get home.
