If it has been sitting for a year, I would def pull out the back seat and change the filter on the bottom of your fuel pump.Also check the condition of your fuel pump.Is it stock or 255?And if you still have stock injectors,throw them in and see if it helps.

are you sure?? i had a similar thread you posted on and said the 19lb are the same as stock? the 19lb accel have bigger injector holes then the stock ones? wouldnt they flow more

Are you sure? Was I on drugs at the time, ? I know that the set I measured were 225cc and the set that Corbin from 2gnt measured were 235cc. Which are both bigger than 19lb'ers. Unless, of course, those 19lb'ers flow more than normal.

Now that number may have come from the way they are listed out there. There are listings from "official" references from 190 to 235cc. That's why Corbin and I flowed them out. To try to get to the bottom of it. He did his through RC and I did mine through Marren Motorsports.

So I would suspect that the OP is running lean right now.

I thought 19lbs were stock so I figured these accel ones would be better. But other than that I have a new fuel filter and I cleaned the net in the tank but I am using a previously used fuel pump. Im sure rhe pump im using is worn out. So I guess ill put a new fuel pump and my stock injectors back in amd then if im still running lean then will I need bigger injectors?

Your stockers should be fine with whatever you have done to your engine. I can't see a reason to replace the pump unless you are showing signs of fuel pressure problems.

I dont have a pressure guage to see exactly what kind of pressure I have but when I was changing my injeinjectors there was no pressure when I used the release valve. after I pulled the injectors out there was only a little bit of fuel in the lines. To my understanding the fuel system should be under constant pressure so either I have a leak or something isnt operating correctly

Sorry about the typo

hey kenny heres a link i found that helped me make more sense with those injectors. like i was saying before about the fuel pump you got not running the same psi as the stock pump. i still believe those injectors i gave you to be good for your motor. all you need is the new pump and a new fuel pressure regulator to dail it in.
