Hello,

I am looking to HP tuners for a possible solution for fuel pump open circuit and fuel pump range performance DTC's

The company i work for is an equipment provider to convert vehicles to run on propane and natural gas. When our systems are installed we disable the oem fuel pump from operating while the engine is running on propane. The challenge is on the newer vehicles where the oem pcm is monitoring the fuel pump circuit (particularly on fords) and turning on the check engine light for fuel pump open circuit. There is also a code for fuel level range performance due to the fact the the gasoline fuel level is not going down and the pcm is monitoring this also.

What i am looking for is a way to "turn off" or disable these monitors to keep the check engine light out (i'm something like a 02 sensor delete??)

Any idea's and input here would be greatly appreciated.
