Fuel pump install issues.
Just installed a Walbro 255 Fuel pump and VF52 with XPT stage 3 map for my wife's 08WRX.
Couple of things I wanted to confirm.
I am finding I have to put the ignition to the on position for 2 to 5 seconds and wait until I hear the pump finish pumping the fuel before cranking the engine over or it will hesitate to start. It is not instant like OEM. Is this normal?
Secondly, when I installed the fuel pump one of the rubber O rings I transferred from the old pump to the new one was a little loose. Is this normal? We thought it might compromise pressure so I installed a new O ring we found in the shop. The problem there is the rubber O ring we replaced it with may not be made to last in a fuel tank. It seemed similar enough though. Hopefully it's ok. Did any one else have the same issue with one of the rubber O rings? If this is normal I will go back in and replace the new one I installed with the original. If not, I will order one that's made for the pump so my wife doesn't find find herself stranded on the highway any time soon.
