i have a recon gauge sitting at my house i bought it to read fuel pressure.i already have egt trans and boost gauges, what i want to know is will the recon gauge work if i only have the fuel pressure hooked up or do i need to do away with all the other gauges and use the recon only??? i would prefer not to seeing how i just bought a new boost gauge!

 

It will work fine just reading the fuel pressure.

Now, with that said it might save you a little money if you send the Recon itself back and buy a Rail Pressure gauge. You will not use the rail pressure gauge but, it also reads fuel pressure and the unit costs less money.

Just a thought. You will need to keep the fuel pressure kit either way.
