Does anyone have experience with adding an inline fuel pressure sender to an EFI system. My goal would be to add something similar to this:

I was thinking to adding this to a tee in fuel line near the frame before it comes up aft of the motor. My goal would be to feed this signal to the 7427 PCM to support a readout in the adx info. Has anyone done this or have any ideas on a path forward?

Should be easy. Wire it up like a TPS but feed the signal wire into an extra analog input the same way you'd wire a wideband O2 sensor.

Could I feed the signal to another pin on the 7427 PCM? I already have the WB02 signal feed to B16 and would like to keep it active. I don't have anything fed to E14 since my 7747 MAP and TPS reference are spliced together. I just don't have clear information from this thread (http://www.gearhead-efi.com/Fuel-Injection/showthread.php?256-7427-install-first-impressions/page3) on whether the 5V reference in E14 is an input signal or an output signal. I seem to think it is 5V output from PCM to MAP based on the wiring on the 7747 and 7427 so I don't think this E14 pin will work, correct me if I am wrong. Any other open ideas for an untapped 5V analog input in the 7427 PCM? I am currently running a 700R4 so I don't know if any of the transmission inputs are 5V reference that I might be able to use?

So could I use the open B5 location - Trans Temp - since I have the 700r4? I would probably use it similar to the oil temp sender found here: http://www.gearhead-efi.com/Fuel-Injection/showthread.php?669-Oil-temp-measuring/page4. I just don't know much about hacking the BYJL $0D Bin yet, but I am open to learning how, more reading...
