How about a roll pin? I have heard about this but not tried it. Guy told me to install the pickup, drill it and install a roll pin. Sounded like a good idea at the time, but aren't roll pins hollow? Would it suck air?

I had one fall out with a bracket. (Moroso) I didn't weld it and it broke at the braket and fell out of the pump on my drag car. Funny story too, we were at Rockingham NC in the 3rd round of a big money bracket race when the oil pressure went to zero as soon as I lifted on the other end. I got the win light and killed the motor and towed it back to the pits. Checked the oil level and fired it up and it had normal pressure. There was no way we were going home because of a oil pickup tube. We added 2 qts of oil and lined up for the 4th round. Made it 2 more rounds shutting it off at the finish line. Got home pulled the pan and checked the bearings and they were fine!!!! Lucky
Needless to say, all my pickups get a bracket and welded now.

practicing on old

new assembly before I Hack it up

Very important step here that a lot of people forget.

Good call Monty
