Just installed new Fuel Pump. But having problems
I just installed Walbro internal fuel pump that was recommended to me by a fellow org. member. Iwas wondering if he can help me out.
My car seems to stall whenever under 30mph or 2000 rpm. What is the cause of this problem?? Could it be the O ring not sealed and it's sucking in air??
I noticed that when i opened up the cover the old O ring had expanded and took awhile for me to put it back on! I also changed out my spark plugs, could the spark plugs be the problem?? I specifically ordered ngk pfr6b-11 but courtesy nissan sent me ngk pfr6g-11. I didn't notice this until i was on the fifth one 
Can anyone help me?????
Please help my baby!!

Those are the right plugs but they are 1 range colder than stock. I doubt that's the problem...
Did you clear the ECU to relearn after putting in the Walbro... If it is the hi pressure one, it runs at a higher psi than the stock. I'm just shooting in the dark... perhaps others here can be of more help.

I thought that NGK PFR6B-11 was a level colder?? Courtesy Nissan sent me NGK PFR6G-11. But I'm thinking that ain't the problem

Yes i was able to tighten the top with ease. I took out he new pump and replaced it with the old one just to see if anything changed. But it kept stalling under 30mph and 2500rpm. So I put the new pump back in and now it's even wose especially when i'm at a light or stopped. It stalls so bad and when the light turned green i hit the gas but the car stalled and didn't want to move. Then i had it near to the floor but car kept stalling
What's wrong with my baby?? Whenever it's under 30mph or 2500rpm it puffs and when at idle rpm stalls real bad like it's about to shut off. Could the fuel have been contaminated???Someone please help my baby
