Oem IC pump concerns after ice box install.

Hello everyone, I recently installed a BMR icebox and I cannot get it clear of air. I’ve tried every trick in the book and what’s recommended by BMR.
Issue 1: I get movement at idle (water in the box and pressure out the blower bleed valve. As soon as I test drive half way down the block “ic fluid low” hits and the pump STOPS working. Does the OEM pump run harder (flow more) in drive, causing a large pocket to move that don’t at idle? Could the pump be shot? 10k miles on the car.
issue two: if I completely remove the bleeder valve on the blower water comes out (at idle) like a faucet not a hose. I was expecting more velocity? Sign of bad pump or normal?
issue 3: has anyone swapped the oem pump for an EMP in the stock location?
I have a 1/2 NPT tap/drill coming so I can modify the BMR box lid/cap to be vacuum filled (or at least attempt that).

Any insight is greatly appreciated. View attachment 592845

BMR reservoir, pump, and race HE total is $1,557.00, or with the street HE is $1,457.00

FI Interchiller is $2,460.00 on their site right now for the stage 2 kit. Stage 1 is $1,618.00

Choose whatever works best for your application. There is always something to work out no matter which way you go.

FI says you want a 3 gallon reservoir with their chiller for drag racing. Here is a link to some info on it. FI Tech article

I think the problem is the pump itself, not air being in the system. I don't think the pump can handle the additional head pressure, from talking to various performance places online. Mine was the same way, When I first installed, seemed like there was good movement of water, but then pretty quick it just is hardly moving. I have used the vacuum tool numerous times, but it's just lack of water flow at this point. I was also told that if the pump air locks, then they don't last too much longer usually.

There is no aftermarket bolt up IC pump that I have come across. I am installing the CWA400 (nobody has the EMP) this week.

The CWA400 pump is $325.00. I talked to BMR fab and FI and neither are very positive about the stock pump. It's designed for the stock system.

I will be posting on the CWA400 install later this week. Going to have to make a bracket and do some creative plumbing from the looks of it.

I am going to put it right where the old one was, at least that's the plan, in that general location. It is clocked completely backwards, iirc, so we'll see what we come up with, ha ha. We can be pretty resourceful when necessary.

You can turn off the cel, car will not go into limp because of the water pump not working.
