Default Injector size question.

I'm trying to identify what injectors are in my truck. The number on the side is 9350 and they are a light grayish color. I think they might be pod's because I can't control egt's when I tow trailer and they haze pretty bad at idle.I can break the tires loose in 2nd,3rd, and 4th gears once the turbo lights and the power screw is only 1 turn in.

I believe you have 40 hp DDP's because the part # is 899350lpm, so the 9350 kinda fits into that.

I'll pull them out and get the number. I plan on putting bosch 190's in to help with the fuel mileage,right now it only goes 150 miles on a tank when towing 8500lbs.

I was shocked to,I stopped a few times to make sure the pump wasnt leaking or dumping fuel into the crankcase. The 12 valves at work in the buses get 4.5-6 mpg,but i didn't think it was possible in a pickup. Ive been having pump problems too so its time for a total injection system overhaul.

Well I did a search and I think I may have a cracked tip. Will I need to get new copper washers if i'm only pulling them to look at?
