Fuel pressure gauge adapter

I bought this pressure gauge:

http://www.amazon.com/OTC-5630-Fuel-...words=OTC+5630

And didnt realize i dont have the port on the fuel rail on me ZJ
I need adapter "Miller 6923", so i can do fuel pressure check:

$120 !!! Is there a cheeper adapter i can connect to the pressure adapter i bought ?

I dont remember having to buy anything for my fuel gauge in order to hook it up. It's not here right now, or I'd take a pic of it for you.

I'm not sure about your 5.2L, but I got this pressure gauge from Harbor Freight.

It looks like it has the "T" connection that you need to put the gauge inline between the fuel line and the rail. It is not a high quality tool, but it did get the job done for around $20.

I dont think I've ever seen one without the port except wj's. I know if you order a new fuel rail now you get the same rail as the wj with no port.

I have never seen a ZJ without a port either, but The FSM actually says that depending on the vehicle model and engine that 5.2L engines may or may not have a test port. I guess I learn stuff every day.

Yep, no test port on mine = Suck

In the service manual it calls for test with or without test port, fuel system/Sec 14-8 - 14-9 . Hence why i need that miller 6923 adapter
Looking for something cheaper i can connect to the fuel rail quick disconnect fuel line and to that gauge i bought.

Im guessing that long silver piece is what i may need but the question is, is that particular piece pictured the right size to fit my jeeps quick disconnect ? There are a bunch of different sizes. Looks like that one is : " 1/4 in. & 3/8 in. barbed T-fitting" ? one end is 1/4 and the other end 3/8 ? I guess i may buy that kit and roll the dice and burn another $20 + shipping on that one.

Since you got an OTC tester, I am almost certain they would have the adapter to go in the fuel line...and I doubt that it would cost you $100 bucks...Worse case, build your own from repair fittings...

There are three Harbor Freight stores in Denver. Go have a look at one before you buy it and see if you think it will work first. My local store had a whole stack of them on the shelf.

Haha you should add that to the "you know you drive a zj when..." thread
