Where to install fuel pressure sensor?

[S10xGN]

think about it,pressure there will always be higher than downstream and not an accurate representation of fuel pressure available at the rail

if the filter becomes clogged or cause a pressure drop (and it will even when new) the pressure before it will not reflect the pressure drop after the filter or of the numerous feed line bends and connector restrictions , i wouldnt be surprised if theres a 3-5psi difference, you really want to know that the rail pressure is 1:1 over boost and holds constant , before the filter wont do it

best is at the rail and must be before the return, ive seen some installed in a tee block at the fuel feed connection off the frame by the steering box , but again it wont show a drop if the rubber line in the engine side fuel line becomes a blockage
if you dont like the look of it at the shrader fitting you can run a 2-3ft braided line to the fender and install the sender there

AFTER the filter! I misspoke, my bad. Same line, different location (by 8 ft)...

Razor, where do you install that sensor on the alky kit? I have an old progressive kit and I already have a bunch of fuel rated pressure sensors lying around, thanks!
