i installed an AEM fuel rail and B&M fpr about 2 days ago but when i tried to adjust the pressure nothing happend. there are no leaks anywhere but my car is getting harder to start. if any one could give me some help it would be greatly appreciated.
how exactly do i just the regulator to get more pressure out of it. i know about the nut and bolt on top of it but im not sure if i got it right. thanx
