What Dog said ideally you want it touching for the vibration potential. Tho many have lasted fine being suspended. If already together I would let it be & if not buttoned up yet I would want it supported. On the stock car I drilled some holes around the perimeter of the pickup & used mini nuts/bolts to give support via contact with the pan but more for making sure the flat pickup screen ain't closer than 1/4" on my high rpm app. Unless you will be turning high RPM's/eng with hi vol pump/enlarged oiling passages then the OE screen/offset partial flat metal design will be fine as far as flow. Support it if you are in that position to change it otherwise if suspended likely you'll be OK

I'm thinking that is a std 4 qt sump pan. Since it ain't running even 3 oughta be enough to not have an issue (for it to prime/drain OK). Describe how it is "sucking air", what's going on? I gotta jog & I'll check back later

I was thinking during the run, did 3/4 qt go into the filter? With that pan 4qts should be in the sump (actually with the correct stick/tube it should be reading full or very close to it with 4 qts on level ground). Did you have close to 4qts in & what was the psi before/after it changed & if not I'd go ahead & get it to full (4qts in sump) & retry it

Did you leave it loose in the block? It should be tightened with a pipe wrench and have high temp pipe dope on it.
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

The OE style pickup has a "shoe" that touches and establishes clearance for flow into the screen. Some aftermarket have the "shoe" and some don't.
If you have the shoe type it is supposed to touch. I certainly believe it has worked fine for many with the clearance. Still I have heard cases where vibration broke the pickup. Not pretty. Stories were on MOPARTs so they must be true... right? Personally, I would re-do it or have the shop re-do it. Plus you get every last bit of pan capacity.
I belive that a lot of the broken off oil pickups where after market pieces, like Milidon and Moroso, that cracked and broke off, not the stock OEM Mopar ones I've been into many, many stock Mopar V8, 273 through 426 street Hemi to U and V code 440 cars that had the pickups either on the bottom of the oil pan from the factory, seeing the witness marks in the bottom of the pan, or they where close enough to not allow the oil dipstick to be inserted sideways through the oil drain hole to clear the bottom of the pickup and pan BTW, for all you that didn't buy your original Mopar muscle cars new there was a service bulletin issued in the late 1960 to tell all customers to add one additonial quart of oil to all cars with the 402 oil pans with the stock windage trays, IE the 1966 to 1971 Magnum or Hi Po 440 and 383 production wedges OP, run that oilpan with 5 quarts, not 4

Getting back to the situation: GTX Max...The tube(NOS Mopar) was tightened securely without dope. Cab Burge...Specs call for 5qt. total. So, are you saying to run 5+1=6 quarts OR 4+1=5 quarts with 402 pans? Rapid R...This is what it did while priming with drill & priming shaft and 3 qrts oil in pan with bottom of strainer 3/8" above the bottom of the pan (which makes the majority of the debris screen 5/8" above the bottom of the pan): oil pressure went to 50 psi,then gurgling sound started and psi slowly went down to 40 psi and we stopped the drill. Added 2 qrts more oil (5 qrt total) and had 50 psi constant with no gurgling. ???? Another question I have is this: With the pickup screen this "high" will solids collect at the bottom of the pan that will not be get suspended in the oil? I like to drain oil when it's hot, thinking I have the solids suspended in the oil and thus are removed when the oil is drained out.

402 pan is a 4qt sump + 1 for the filter , 5 total .
I would put dope on the threads to make sure it's sealed

Hey,JohnRR,
What's your take on the height of the strainer? The bottom of the strainer is 3/8" above the bottom of the oil pan which puts the horizontal area of the screen +/- 5/8" above.
It's too high off the bottom to me , the strainer is designed in such a way that it can be closer to the bottom of the pan and not have a problem drawing in oil.

I agree with John. It probably should still seal if the pickup was tightened well but since you're sucking air I'd definitely put some high temp dope on it to rule that out.
