ok well i just put my JDM h22a in my eg civic. And well we didn't feel like running a long *** fuel hose to the jdm fuel rail so i went and got an f22 fuel rail..where it'd be just right there and i wouldn't have to run a long hose over my head.

So yeah anyways....its hesistating now like its not getting enough fuel to the injectors and its in for a jerky ride when just crusing thru town, not like super bad but enough you can tell and have to push the gas a lil more just to make it stop hesistating like it does. So what i was wondering if there was any difference of how much fuel is running thru the f22 fuel rail and the h22a fuel rail b/c if its a big difference then i'll know why its hesitating and jumping like it is.

Also, im still running my stock fuel pump from my d-series, but i did buy a new walbro 255lph for it so i figured that'd help it hopefully from hesistating..but yeah i need help!!
