How much presure do you think is on the bracket that holds a belt driven fuel pump I have to make or modifie the bracket on my BLP pump. Thanks

I run an 80a-1 pump for methanol constant flow fuel injection. Pressure is 60 psi at times. It mounts with two four inch bolts through a casting, to the cam cover threaded holes in the block. One is 3/8, the other 5/16 diameter. No problems in twenty four years.
Here is the big block mount kit, etc The bracket that holds the pump is just left of the big silver pulley

You can mount the pump on the driver's side like I did by drilling the smaller hole in the bracket to accept the larger bolt. Some massaging of the brackets was done as well to make it fit where I wanted it. I use a different length belt as well.

Thanks I did a lmost the same thing it looked felt strong enough never hurts to ask thanks again
