Can't find how much to tighten a factory small block fuel pump in my PDF file style factory chassis manual. Anyone remember? My best guess is about 25 ft/lbs.
 
What's the bolt size? 5/16 about 15 LB FT, 3/8 I wouldn't go more than 20. It's going into aluminum.

But since this is my opinion, throw it in the garbage can.
 
The 68 service manual doesn't list a spec for the fuel pump for the sb.

It lists the bb and hemi fuel pump at 30 ft * lb with a 3/8"-16 bolt. That is going into cast iron though...
 
I was gonna suggest about 15 to 18ft lbs shouldn't be a lot.
 
I've gotten away with torquing the water pump and fuel pump bolts to 30 ft lbs.

They really don't spec it in the service manual... So I just use the timing chain cover torque for those bolts...

I haven't had any problems breaking anything at that torque...
 
Tighten it till it breaks and back it off a 1/4 turn. lol
 
After 47 years of tightening stuff, my arms and wrists know what the threads want.Now dont go getting all indignant on me. I still torque those fasteners that are inside.Just because, If the customer asks I am going to have to have an honest answer.Those muscles have built in memory.Its uncanny how accurate they can be.Its like walking.Its become automatic.When you get up in the mourning, you dont have to relearn it.Your muscles just do it.
Well, correction; Harley Davidson. Almost every single bolt on a Harley D has to be loc-tited and torqued.If it comes loose, there will be H to pay.And they do come loose.I want to know that I did everything possible to prevent it.
And certain motorcycle chassis parts.Like calipers.A guy could die if his caliper fell off.
Ok so I do still torque some stuff.lol

like others said there seems to be no listing for them on the small block list anywhere i look. I also have torqued them and never had an issue but this is a list i found and use


Chrysler Torque Spec

Mopar guys, this is just for you. We've taken all the guesswork out of Mopar torque specs.

These specs are for stock-type bolts with light engine oil applied to the threads and the underside of the bolt head. Moly and other lubes offer reduced friction and increased bolt tension, which will affect the torque figure. If you use aftermarket performance bolts like ARP's, you should follow the recommended torque specifications.

Please note that some specifications are in inch-pounds rather than foot-pounds. Read the charts carefully to prevent broken bolts due to excessive torquing.

25 foot pounds seem to much to me as well. I have always just snugged them up, and never had a problem.

Snugged down + one grunt sounds about right.

Problem is the grunts get longer and more as people get older.
Heck, for some folks it already takes a good grunt or 2 to pick up a dropped wrench of the floor again...
I can still do that in half a grunt though...:D
