fuel pressure

[bc...@juno.com]

I have been using this type (solid state) sensor for fuel pressure on
electric and mechanical fuel pumps with good results this year. I
would NOT use the old fashioned mechanical type which can
vibrate, leak, or break. These come in many ranges, I see from
15psi to 1600psi, from multiple suppliers, mine are 15 and 60.
Mine are coupled to an electronic dial readout, but the signal can
be used many ways. Note, any pulses coming from the system
will come right thru on the signal. Bruce Roe

Hi,

I am unfortunately still chasing my tail on my EFI install and the piece of data I do not have is a reading for fuel pressure. (the rv still randomly dies and I am not sure if it is fuel going away or something else - but I need to eliminate the fuel going away).

I have tried twice to install a FPS and both failed. the first one was undoubtedly my fault. I tried to run 12v power to a 5v sensor which obviously didnt work well. the second time I bought a 5v step down and a similar sensor to the one I had before. I started the RV, seemed like it was working correctly then the pressure eventually went to 0 and it never reported again.

both times I just bought a 30psi sensor off amazon that were really fairly reasonable in price (want to say under $20).

at this point, I would love someone to just suggest a combo of stepdown and sensor that should be a 'known good' and take my decision making out of the mix.

suggestions greatly appreciated.
