fuel pressure warning

[jkern]

ok, guys i know this has been discussed alot, so maybe all i need is pointed in the right direction. i have done a search but found nothing concrete. i am planning on installing a pressure switch on the post-filter side that will illuminate a LED when the fuel pressure falls below about 5 psi. is this a good number to use for a low pressure warning, or should it be more. i have a pressure switch that is good for 3. 5-8 psi, and just needs a little calibration.

thanks

Jeremy, I'm running a 0-20# p. s. i. Westach fuel press. gauge w/red light low press. warning set at 5# p. s. i. This was a special order as their reg. fuel press. is 0-15#. The low press. warning is user adj. to what you want. Also has an output for a buzzer if you want but the red light is BRIGHT! Works great for me hooked up at the inj. pump,14# idle and never less than 8# towing... Howard
