rb26 s13 problem

[douahawj]

hi guys i got a s13 and doing a rb26 swap but ran into a little prob. cant find any info on this swap but the prob im having is that im getting to much gas into the engine i ran the power to the pump from the battery with a switch to turn it on and off. everytime i turn the switch on the car bogs as its getting to much gas and then when i turn it off it runs and runs find as there is still gas in there. i was wondering if anyone that has done this swap how did you wire up your fuel pump oh i also have a treperformance 225 fuel pump.THANKS

Do you have your regulator on the correct end of the fuel rail?

[douahawj]
