installing new fuel injector - question about tightening

[Texas Diesel]

I have a concern about snapping off the screws for the hold down clamp.

On page 5-187 of TM 9-2815-210-34-2-2, the instructions state to tighten the screws to 150 to 175 pound-feet. That seems like an awful lot and I would take a real chance on breaking the screws off. Is "pound-feet" correct or should it be "pound-inches"?

I have torqued them down with the torque wrench set to 50 pound-feet and not been able to hear a click on the wrench before the screws are so tight the fear of breaking off starts and I stop tightening.

Any knowledge shared on this process is very much appreciated. Thank you.

150 inch pounds not foot pounds or 12-15 foot pounds. Yea you stretched some threads.

there was a miss print in several manuals.

30 ftlbs would prob snap them off. Make sure you replace them since they're most likely stretched now.

Worse case just use a standard cart for bolt size.https://www.boltdepot.com/fastener-information/Bolts/US-Recommended-Torque.aspx

Thanks guys, yeah, common-sense was telling me "this just doesn't feel and seem right". Now to see if I can back them out without snapping off, always seems to be something that complicates an easy process.
