A friend at my American Legion has a 2003 Ford Escape. One day the car would not start. He had it towed to a local shop he had used before. They got it started but intermittently it would not start. They installed a fuel pump, relay and a fuel filter. Ever since then he said would run but would flash a low fuel light when his gauge said half tank and he would only put in 8 gallons and then the gauge read full. He also had a code related to fuel tank capacity error, can't remember what code I pulled out of it. He did not have this problem till pump was installed. I told him, after many questions, that it sounds like a cheap fuel pump. He wanted me to change the pump. I ordered in a Motorcraft pump and a Motorcraft relay. The access was under the rear seat. Easy access. I did the pump and relay in one hour and I charged him $60 and I also did some clean up that the other shop did not do. The hole where the pump mounts has a raised hat area where the big round lock collar threads down to hold pump in place. Lots of dirt and broken nut shells there. I cleaned that S-p-I-c-and-span before old pump removal. It amazed me that the shop did not clean that area. Ran great and he has driven for 2 weeks now and he went below 1/4 tank, on purpose, and only got the warning light at 1/8th tank and no CEL.
