Easiest way to check fuel pressure?

[Zero Signal]

I have a gauge you can borrow, Scott. Call me or email if you want to borrow it or just come test it at my place.

I'am going to install a pressure gauge do I pull out the little thing that looks like a valve core from a tire?

Someone brought this thread back from the dead.

Thanks John, but I borrowed one from my uncle. Read 26-28psi at idle, and 36 with vacuum disconnected. Everyone said that was normal (except the haynes manual), so I am ruling that out of the equation.

So now I am down to excessive carbon in the cc's and my MAF being the cause of my pinging.

I have some excess money left over since the gear install went without a hitch, so I might put it towards a full top end cleaning & a new MAF.

Black, very funny. i dont know John at all, but sorta know Scott a little - try to be cool with fellow tucsonan stangers. it was intended as more of a future invitation to borrow tools or help out either of them.

It's nice to know fellow mustang owners. They always seem willing to help out in a time of need. Maybe it's genetic??

I Met John (Zero Signal) off of stangnet. We originally linked up to go out to speedway and meet some more of the mustang guys out there. Ended up fixing my car all night.

Stupid coolant bypass hose spewed coolant everywhere. That turned a Friday night into tons of fun! But the 24hr autozone + John saved me.

Last time I let something stupid like a rubber hose screw up a night out. I couldn't afford it at the time, but I replaced every coolant hose the next day. I still need to take a pressure washer to the engine bay though. Antifreeze on the skin really sucks.

Sounds like madams74 has the cheapest/easiest way. I don't like the idea of a full time gauge hooked up (another spot for a fuel leak), but it sounds great for sporadic testing use.

And why the need for glycerin filled only? Is this to prevent fuel leaks, or damage to the gauge?

Glycerol - A sweet syrupy hygroscopic trihydroxy alcohol C3H8O3 usually obtained by the saponification of fats and used especially as a solvent and plasticizer.

The glycerin is just to keep the needle from bouncing around and gives you a more accurate reading. ON the engine you need it, on the firewall or in the car you could use a regular gauge. PLUS it usually means a better quality gauge.

in addition to working as an insulator for fuel pressure gauges, glycerin [with water] also works well to keep cigars in a humidor from drying up.

Scott, i look forward to meeting ya sometime. ditto for John, though i have not ever chatted with him in here.
