HPO Gauge ?
I have a 3000 psi fluid filled gauge that I want to hook up as a HPO gauge. Will this work and where do I connect it. I was thinking about just leaving it hooked up under the hood. If 3000 psi isn't enough, I can probably get a 500 psi.

no you want a 3000 psi gauge the oil system will pop the 500 starting it up hook it up to the oil rail in the head there are 3 availible ports in each head they are plugs along the oil rail take one out and put the correct fitting in and hook up the gauge

Thanks Ronnie. That 500 was a typo LOL! It was supposed to be 5000. It's ok to just leave the gauge there permanent isn't it?

This might help:
HPO Gauge:
You might spend $60 or so on high pressure hose, fittings, and a quality 0-3500psi liquid filled gauge, but having this hose available for future diagnostics will make it worth it.
The hose which you will need will need to be about 40" long, rated for
(minimum) 3000psi working pressure (12k psi burst rating!) with the gauge on
one end, and a #6 female JIC swivel fitting crimped onto the other.
You will also need an individual fitting to screw into the head to go from the
head to the hose. This single fitting will be a 90 degree fitting # 5 "male boss" (sometimes called #5 o-ring) on one end of the 90, and a # 6 male JIC on the other end of the 90.
Using a 5/8" wrench, remove any one of the HPO galley plugs, and install the 90deg fitting into the hole. (save the plug for reinstallation , after testing). The O-rings are reusable, unless brittle, cracked, etc... The single 90deg fitting will have a "jamb nut" on the O-ring side...screw the
fitting into the head, "aiming" the 90 away from the turbo, intercooler pipes,
etc...and then tighten the jamb nut, to "squish" the O-ring also locking the 90
from "spinning" around as you attach the swivel end of the hose to the 90. No
sealants, loctite, or teflon tape are needed on "JIC" or O-ring fittings...and
don't overtighten them...usually about 180degrees with a wrench past finger tight.
I just copied and pasted, but you should get a real good idea what you need to have by reading through this.
