Installed a 0-30 psi gauge yesterday. I tapped into the filter housing; the '99 has two 1/8" pipe thread ports on the top of the filter bracket, inboard port is post-filter. I used Mike's recommended Weatherhead needle valve feeding into a tee; pressure line to one port, Kohler engine oil pressure switch (NAPA SME 2509927S) to the remaining port to activate a low pressure warning light. Good news is all works well. Bad news is low pressure (big surprise here,eh?); 10 psi engine not running, 7-8 psi engine idling, 5 psi around town & 65 mph cruise on highway.Solution is not all that clear. Presently the truck is stock, 173k miles, seems to run fine, no starting problems, no history as to whether this is original IP/LP, or if replaced when it was done. There is some seepage at the grommet where the fuel heater wires enter the filter bracket, and there is a fuel leak from the top of the tank that went unnoticed until the tank was filled. In addition, the tank only took 25 gallons to fill when the low fuel light illuminated at an indicated 1/8 tank.I'm looking at an aftermarket LP, possibly FASS platinum, and dropping the tank to address the leak/sender problem. From what I've read I should expect that the IP's internal diaphragm is cracked, to be prepared to experience hard starting issues at a minimum with a new lift pump, and perhaps IP failure in the near future. Not sure if I should keep the OEM fuel filter to retain the fuel heater & WIF indicator, or even if repair of the leaking grommet is possible. I'm not comfortable driving it now for fear of IP failure, but what to do with the full load of fuel? Looking for guidance. In the mean time I will move the gauge to the filter inlet to look for pressure drop across the filter - won't do a thing for the IP's diaphragm, but may indicate a blocked filter & give me the faith to drive the truck until the tank is empty. Thanks for the help,Joe in St Louis
