I miss placed the two mounting bolts that attaches the rear of the injector pump to a "T" like bracket that bolts to the block. There something like 3 to 4 inches long. Need the exact size so I can purchase a couple of grade 8 bolts to replace these. Thanks in advance for any advice

 

M8x1.25x90 (I guess 90 is length in mm? 3-35/64", if so) Cummins pn 3913366 I was able to look it up in Cummins Quickserve - a very handy reference for finding part #s, procedures, specs, etc. If you have your engine serial # from the data plate, you can create a Quickserve account.
