I bought the first pump from Rick at sts and later told him the problems I was having and he said he didn't think it was the pump as he had never seen a bad one, so not knowing what else to do I bought another one from neweraperformance and for some reason I got 6 wot runs that were awesome then pulled into a gas station put 10 gallons in and took off with this big smile on my face and it went back to the same **** as before???

 

Are you SURE the inline pump is working? Mine worked for a while then stopped. It had a bad ground. The crossmember I mounted the pump on wasn't grounded well. I had to move the ground to the frame rail.

When I would check the pump, I would think it was running when it really wasn't because it was picking up vibration from the intank pump.

 

There is no inline pump, it is the 340-255 walbro intank pump.

 

CHeck your rev limiters. Get an updated tune to make sure they are good.

 

 

Updated tune on the way (the forth one) but Allen said that the rev limiters were set higher then the factory was from the beginning.

 

you got 6 wot runs that were great and then it just went to **** again!!!.does'nt sound like its the pcm tho....

 

I know????
