Fuel pump Torque Specs?
Hello. My question is about the torque specs. on the two 1/4" bolts that help to hold on the fuel pump plate on a s.b.69. The AIM says 32 to 40 lbs. I got thinking about it , seems high for a 1/4" bolt and wondered if there had been a revision to that number. Should I try/ risk that or just tighten it and simple check a few times for leaks. Thanks in advance for advice.

Thanks for the replies. The chart from 69L88 would be about what I would think, that's why I was confused.
The AIM I have is for 69 and on page J207 it list the "srew Asm #11" at 32 -40 LBS.FT not inches. Perhaps by 72 as in Sunflower 1972 screen shot they caught the mistake. If Sunflower 1972 notices this reply couldyou tellme what is the spec they have listed for thos bolts. I can't make it out in the shot you posted . Thanks and take care.

I think you have to relook at your aim, it will say pounds but if you look closer it says INCH pounds
