The 800-170 connects to the fuel filter outlet. The LFA116 connects to the 800-170. The LFA80 connects to the LFA116. The fuel pressure tester connects to the LFA80.

The rest made sense, I just didn't think it would be that style of thread.

Yup, service port is 1/4" MIF, with a Schrader valve. Don't need a Schrader for the test adapter. Just need to wrap a rag around it when you disconnect it ;)

Great write up. Thanks for spending the time to inform us with this great information. I don't know what else you could have added. Thanks again.

Thanks, I hope it was helpful :)

what size is the flare wrench to remove the fuel filter Captain Hook??

16mm for the flare nut, 5/8" will fit, but it's tight. 20mm on the filter, 13/16" will fit, but it's sloppy.

Thank you so much. I guess 16mm flare wrench is a specialty wrench can't find one. Guess I'll try sears. Thanks again.

16mm crow foot flare nut wrench, (Sears has them) on a 3/8" ratchet works great.

My 2000 blazer zr2 cranks, but won't start. Narrowed down to fuel. Threw money at it when fuel pressure tested below 55 psi cranking. New pump didn't change a thing. Wasted time and money. Started thinking pressure regulator. While I was searching more about how to further diagnose that, I hooked up battery charger to maintain. Damn thing fired right up. Unhooked battery charger and it reverted back. My question is how is this possible? My battery tests at 13 volts unhooked.
