yes thats right, I have a question about a vp44 because I know many of you guys have had 2nd gens..its about my friends truck. His vp44 was dieing.He just put on an industrial injection hrvp44. for the first week it worked ok it would stumble a little and had some hiccups. Now he can not drive his truck. It is very hard to start takes a few cycles and when it is running if you bring the rpms up and let off the throttle the truck will die. And now his aeromotive pump does not prime when he turns the key to the on position. Do any of you guys have ideas of what the problem is? Industrial injection said bleed the lines, my friend has done so, several times and there is no air in the lines. I am not trying to bash this product at all. Im just seeing if any of you guys might know so we can get his truck back on the road.(His trucks sig: 1999 4x4 ,mach4's,drag comp,Bell usb,dtt, hrvp.) thanks
