I am trying to find this adapter for the schrader valve for my car so i can test the fuel pressure on my 1999 Blazer ZR2

So i would like to know the size of the adapter that screws on the schrader valve placed on the fuel tube for testing fuel pressure on my 1999 Blazer ZR2

I mean a adapter that depress the valve inside the schrader valve so i will be able to read the fuel pressure

On the picture to the left you can see the schrader valve i need an adapter for and on the picture to the right is the adapter that must depress the valve inside the schrader valve so
i get hold of one with the correct size

What i need to know is what type of adapter i need that also will compress the schrader valve so i am able to read the fuel pressure on my 1999 Blazer

I would appreciate if any can post a picture on how the adapter that goes on the schrader valve looks like inside/the part that release the pressure so you are able to read the fuel pressure

 

If you rent a fuel pressure tester from auto zone it should have the fitting inside. However, that first one that I rented when I tested mine was missing that piece. So if you rent one make sure everything is there.

 

Not common to rent tools up here in northern Europe

A fuel pressure tester kit is something you will have to buy or loan one from a friend

I have a few friends that might have the correct adapter for the Blazer

 

I guess that would make it tough, I am guess there aren't a lot of Autozone stores in Northern Europe.

 

I talked to the previous owner on the phone today and he told me that he had a Chevy repair shop change the fuel pump and air mass sensor(MAF) on the car so he was sure that the fuel pump was not the problem

He told me that he have never changed the fuel filter which i have bought but not replaced yet. I have to check the distributor cap as well but since i live in Northern Europe it is winter/cold outside so to repair a car outside does not tempt me to much

I have to check the fuel pressure anyway because when i bought the car it had been standing for over 2 years


Once my Mercedes SL stopped and when i checked the distributor cap the charcoal pin in the distributor cap was totally worn out.
There was nothing left on the charcoal pin so it is strange the car started before the engine stopped
