Actually, I'd say more of a fuel tank.
I just recently installed a walbro 255 lph pump, following all instructions. I put everything back together just as it was when I took it apart.
Now I find when I undo my gas cap when the tank is nearly empty, I get that pressurizing hiss, since I have had that in another car, I considered that normal. What is abnormal is sometimes during driving, I will hear the tank do that same hiss with the gas cap on.
I am a bit concerned if my tank is creating a vacuum, which would cause the pump to work harder, shortening its life.
I also have a FPR to install that I haven't yet, but I was under the impression that since ours is a return fuel system, having a 255lph with no regulator wouldn't hurt anything.
Some tips/advice would be very welcome.
