Walbro 255 not working
Hello guys. I have a problem about fuel pump. So when i bought my evo, the fuel pump was faulty. So i replaced it with a 40$ one which was cheaper than the oem fuel pump(300$). But still the car is not going well. So i bought walbro 255 pump. Although the fuel pressure at idle is 32-33 psi with the cheap pump, it showed 22 psi with the walbro pump. I thought the problem can be related with the walbro and i sent it to be checked. It came to me yesterday and there was not any problem with that. So what can be the solution? Should i get oem a fuel pump although it is very expensive? Can the problem be related with fuel pressure regulators? I am waiting for your replies.

Possibly bad FPR. Def not the pump if you're getting black smoke..

Car is running normal with the cheap pump and it shows 34-35 psi at idle although it should be higher. The problem is that when i changed the pump to walbro, the car started to work weirdly and the pressure was 22-23 psi
