Failing lift pump motor

[mhiscott]

Im in the midst of a long trip cross country and my lift pump has started to go out. See the video below. The pressure drops when the truck hesitates both at part throttle and at idle. I popped a gauge on the lift pump and whenever it hesitates you can see the pressure drop way off.

I'm trying to find a replacement motor quickly while I'm on the road, but will it last long like this before it stops working entirely?

Thanks for any thoughts or experiences you can share.
