Where is the fuel pressure testing valve?!?!
 

Hey guys, I've been into this all of Saturday trying to figure out where the Schrader valve is to test the fuel pressure in my 01 D2 w/100k. For the life of me, I can't find it.

Sticking up from the passenger side fuel rail next to the IM, I get it... but can't find it.

Any advice...? I've been pouring over the engine cell without luck and starting to doubt my competency...

Do you have the upper intake off?

Can you see the fuel rail?

On the NAS D1 it is on passenger side. On the NAS D2 it is rear of driver side. See attached page from the RAVE, item 2. PITA to get at.

Aaah! So it is under the IM! Thanks a ton guys... I will check my pressure and get back.

OK, if I take my IM off to reach the fuel pressure port and clean out the IM, should I also be replacing all the gaskets...? I would assume so normally, but do you guys replace all this stuff EVERY time you remove the IM? (Which it sounds like this is the precursor to A LOT of other repairs and maintenance jobs)...

And if so, do I just get the two little ones that go between the air intake and rest of the IM? Or the big one that goes under the whole IM in addition? Intake Manifold, Top End, Engine, Discovery II - Rovers North - Classic Land Rover Parts

Or does it just depend on their condition...?

The upper intake can come of as one piece so you would only need one gasket if removing it. It's metal and some people reuse it. It's $10 at rovahfarm so I just replace it when I have it off.

You can get to the pressure test port without removing the intake. It's not as tight right there as say the spark plug wires that crazily people insist in replacing with the upper intake still in place.

Dumb ass Question of the night #2...

I am trying to read fuel pressure. I have a pressure gauge. It reads nothing. O psi. Does the engine have to be on...?

I managed to get a reading without taking the IM off (Thanks Jafir).

I have the key turned to on, but the engine is not running... I thought this activated the fuel pump...

Ideas...?

I have the fuel pressure gauge from Harbor freight. I had to trim down the oring in the fitting to make it be able to push down the valve in the D2 fuel rail. It was probably just because the location of the valve made it so that I couldn't tighten the fitting enough.

Normally you should have some pressure residual even with the key off.

Ok, so at first I had some fuel squirting out even when I had the key of and the schrader valve wouldn't engage. I tried to get it a couple times, but Now, no fuel squirts out, even with the key on. Does this mean my fuel system is unpressurized and thusly the fuel pump is shot...?

(Now, while this pressure tester works fine on reading the tires pressure , it won't engage the schrader valve on the fuel line and has never quite given me a reading)

Pump only runs for like two seconds when turned to position 2. If you don't hear pump running then pressure won't be there either. Check wires at pump connector under carpet in back?
