1990 Ramcharger 360 TBI with A518, we are converting this to a carb, making a hot rod street truck, can we just replace the in-tank pump with an older Ramcharger sending unit and use a mechanical fuel pump? We didn't know if the tank changed when they went to throttle body, if we can do that, how do we get the factory fuel gauge to work? The bigger issue will be what can we eliminate wire wise from the computer? We will be going to a standard Chrysler electronic ignition setup, we are just not sure what the factory computer all controls in these vehicles, don't want to eliminate any circuits/wires that we have to retain, and would like all the factory gauges to work as well, this is just for a street toy that will be getting a cam, intake, Holley 600, and good exhaust, I can find tons of info on GM TBI to carb swaps, but nothing on the Mopar swap, I know someone has had to do this before, I just want to do it correctly. Thanks!
