I am going to order 1 today and says it should be here by Friday. I will change it out Saturday and let you know my results.
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
So, could a person do as with the 5.9s and route the return back to the line in side of the of the pump. Then fuel pressure is maintained on the line in and return side of the pump.Basically it's the whole banjo bolt that connects the fuel return line to the injection pump. It has a small wire spring in it and a ball bearing and seat that act as a pressure relief valve. They're very susceptible to corrosion and wear. This bleeds off internal fuel feed pressure in the pump which causes power loss, and in extreme cases even causes hard starting.
It's the banjo bolt in the line coming off the side of the pump at the front end. Don't buy a factory replacement. They're junk. Google " Torktec OFV-20" and buy that. They have stainless internals, stainless spring, and a hardened seat. They're also adjustable so you can raise your fuel pressure, but they come preset at factory spec.
Higher feed pressure will provide more power all by itself.
You could, but the only benefit there is if you have an engine that consumes enough fuel that you need larger feed hose and dual inlet ports to the injection pump, along with a much higher performance fuel supply ( lift) pump.So, could a person do as with the 5.9s and route the return back to the line in side of the of the pump.

Did you re prime the system? The MW pump can be a pain to prime if you drained a lot of fuel. Overflow/return line wont cause the truck to not start.I put the old one back in and now it won’t start at all. Please help.
Outside of the things you’ve already addressed, such as filters, the thing that made the biggest difference was when I had my injectors overhauled. I had tried the cleaners but they weren’t able to get them clean for some reason. Maybe because of the JP8 we had to use in the Army?? Either way it might be the same for you if you chase all your adjustment options and still aren’t satisfied.I get where you are coming from willwagner but when I first picked up my truck it ran but was very weak on power. Since then I replaced all the fuel filters and fuel lines and cleaned everything up. I did see a difference in performance and power but still struggled starting off the line and pulling even little hills. So I decided to tweak the pre boost fuel screw 3 turns out and 4 clicks on the aneroid valve and such a difference off the line and on straight away. It’s like night and day but I still lag big time on hills so this is where I am at now. Looking for minor harmless little tweets to give me a little more pull up hills.
Alright, now you can start turning your fuel up. Never a good idea to do tuning with bad components in the system.Just got done putting the new OFV back in. Took a little bit of work priming it but it finally turned over. Took it for a ride and definitely better throttle response and more power on the straights but not much difference on the hills.
