Should I consider safety wiring the oil pump pickup to the oil pump too?
It's a tight a** press fit in the pump and it also bolts to the bottom cover, I really don't want to tac weld it.
I'm 3/8 off the bottom of the pan >last pickup (wrong one) was 5/8"

I've used safety wire for other applications, never failed.

It's best to take it to a good welder and have it Tig'd. I honestly don't think that's the right application or place for safety wire.

x2 , you'll be hard pressed to find a press in pick up tube that won't break the bracket and fall out, tiggin it is just piece o mind.

I would rather have the pick up welded, but if you had to, I have seen them with a set screw drilled and tapped into the pump base and Red Loctite a set screw into the pickup tube, safety wire won't keep it from moving, just from out and out falling off....FWFW, welding does not hurt the pump if done correctly.

Ray, put more than a tack weld on it, or it'll break. I'd put a minimum of (2) 3/8" -1/2" beads, 180* from eachother.

If it has a decent bracket that bolts to the pump, I don't see a need to weld the pickup. It then becomes a one time use type thing, and you may not be able to take the pump apart for inspection and cleaning in the future.

My first build the dooley oil pickup wouldnt fit into the pump, so i put the pump in the oven at 250* and put the pickup in the freezer. I could then get the pickup into the pump and when both became the same temp it was solid, least it feeled that way. The dooley bolts to a main cap so i also did that. Well during my tear down of my motor i unbolted the dooley pickup from the main and it fell off!! I never noticed oil pressure issues and i tend to watch that gauge alot but still. This time around i drilled out the pump and had the pickup welded to the pump, following the instructions given to me by Stefs/B&B. Lesson learned.

The only thing that bothers me a little bit about that one is the support bracket looks to be fairly light gauge steel, which could possibly crack due to vibration. One of the dirt track engines that I build for a mod had something like that happen, fortunately caught it during an inspection before it broke all the way and I beefed it up some.

It does look like if you welded that pickup, you could still open the pump if necessary, many are not like that.

I have ran the same pick up. First, that brace will fail!! Second, I have never had good luck with milodon pickups. I don't know if it's the perf screen they use or what, but I have never had good, consistent oil pressure with them. At least in a boat. I have completely given up on iron pumps because of the pics below. Miliodon pump, MADE IN THE USA, second iron pump to fail in the past 18 months. I think alot of the problem lies in the fact that the old pumps would not clear the main bolts on the GEN 6 motors, (or a main stud on a MKIV) without modification. It use to be that if I was running main studs, I would either have to grind the stud nut or run a stock bolt on one of the inner mains. So they have changed the pumps and they don't seem as strong as the older units. Have not been able to find a pump that is built off the old blueprints anymore. It also would hurt if the cutter for the hold bolt wasn't quit so big, and if you/they would radius the area where it cuts into the body. This pump broke due to a bad shake from failed drive shaft, unfortunatly, the pump broke in the next race. :)stJMO.

Note...the pic above is my prior pump, I just posted the pic to show it also bolts to the pump.

My new Mellings is their "performance CNC" HV offering.
Same type of PU (also bolts on) but is a 1/4" deeper to give 3/8" off the bottom.

I'm having difficulty making it to a welder after work before they close!!!
