there is not a bleeder valve on the pump, so i wonder what you are referring to? the few ports on the pump do not use any type of sealing washer as the pressure is too high. if it had a brass or copper washer that may explain why it blew out.

 

[lenz1079]

it is the bolt that enters the housing just below and to the right of the brass nameplate. so what are my options

 

[m-35tom]

that is the fuel delivery check valve. very high pressures here, no gasket, torque it to 40-45 ft lbs. loosen and retorque 3 times total. if it still leaks replace ip head. this fitting is matched to the ip head, do not swap from any other ip head.

Here is the information from the TM to back up what Tom stated (torque should be a bit higher, perhaps).

OK, after following your information, and thank you thank you, survey shows that the bolt and hole are shot!. Now:
1st Question..... what is the NIIN for an injector pump Head, i have acess to the govt and their parts.
2nd Q.... if i cant get it from the military, where else and maybe a cost estimate.
you guys that answered me have helped alot, again thank you. i guess i know why my free & running truck was classified as H7. if i can look for any parts for Bjorn or tom let me know, ill try my best

The number on the head should be 90100A.
