I am new to the forum and so far have found the information very useful while I have been researching cng options.
I am at a sort of impasse.
I first looked at positive pressure, diaphragm, or pneumatic-whatever you want to call them and like that route because the conversion seems less expensive.
I then had another conversion shop tell me all sorts of negative toward that system and attempted to steer me towards the port injection type of system for my truck.
I then learned from another conversion shop that a port injection system is impossible with the 7.4 Vortec because of the OEM intake manifold design; not enough room between the two plenums to fit CNG injectors.
My question, what type of system WILL work on my truck and where would I find the best quality system for my truck.
Thanks all
