M809 and M939/M939A1 configs would have the same NHC-250 engine. Only a M939A2 config would have the Cummins 8.3.Jarhead,
What series truck (M939 or M809) engine did you get the kit for? 1/4 or 1/8 npt fittings? I haven't had time to make it under the hood of my unit. The factory kit is a lot cleaner install.
Thanks

Parts I used are listed in this thread:patracy,
I understand that the same engine is installed in both series trucks. The question is; Are the fuel line end fitting the same? (1/4 or 1/8 npt) respective to the newer M939 trucks. I ask because Pittsburg Power asked the same question. This led me to believe that the newer NHC 250s in the M939 trucks may have larger fuel line/fittings compared to the older M809 trucks. You mod was to a M939 (nice fab by the way) do you remember the end fitting size that threads into the block?
Thanks

Pump bolts? You mean the fuel rail ports on the head? I tried that. Shattered a bit. Problem is, they're so small.On those pump bolts that are impossible to get out, have you ever tried using a stubby allen socket with an impact screwdriver to popem loose?

I tried heat, but didn't have much luck. Of all things, the trick of the valve lapping compound worked wonders for me. I'll keep that one in my bag of tricks now always!It is locktite that is holding it in. Just add some heat, let it cool and it comes out easy cheeasy.
I used patracys list of parts earlier in this thread.AMG,
Did you piece the kit together or use a Cummins kit? Did you remove the toe board in the cab?
