What is this area for? Fuel pump cover

What is this socket and what is the function of this portion? When i took out the sensor there is a rubber inside. I have a problem where my pressure is too low, around 0.5 bar so my car could not start. Tried changing with a new pump and it is still the same. Tried rewiring as well. Need help.

yea, that's the one. There's a socket on that tube. I am wondering what that socket is for and what that tube is for.

Maybe this thread can help you figure out your problem: https://www.evolutionm.net/forums/ev...evo-8-9-a.html

Are you installing a Walbro 255 pump?

my pressure is too low even after replacing with a new pump. I dont think the pump is the issue.

How did you adjust for 255 being shorter than stock? How did you keep pump from pulling off of grommet? I forgot to look at my pump hanger last night. I'll check tonight if low fuel sensor can leak pressure.
