Fuel pressure test port & the tester connection problem

so I bought this fuel pressure gauge with the connector like the pic below

it screws into the test port on the fuel rail perfectly.

But there's no pressure when I start the car or put key to "on" position.

after unscrew the connector, i see no fuel residue or smell around the area.

Is it possible the connector's nipple is too short to touch the nipple on the test port valve?

what do you guys use?

mine does have a metal thing to depress the schrader valve.
Maybe it is way too withdrawn inside so it doesn't touch it?

Would you tell me what make/model is your gauge?

 

THAT'S THE TICKET!

i use a long needle plyer to unscrew the nipple , and voila! it works and i got pressure, but i guess i unscrewed it too much and when I start the car, gas was oozing out of the connection area!

 

i think it is an adjustment issue, it isn't broken, i just unscrewed it too much

 

report: everything good. just mess with the gauge nipple's height by screwing and unscrewing it, u'll be good

but it raised one more problem

i always tested the fuel pressure when the car is cold. That is fearing if fuel spills it would catch fire.

now, after I tested the fuel pressure, there's no way to not to leak any fuel, sometimes a lot.
Another fact is that you have to start the car to have fuel pressure. Even if for 30 seconds of engine running, the header will be hot enough to be concerned.

How do you guys avoid that risk? by unscrew the fuel pressure gauge after the car went cold? That's the only way i can think of. Any other ways?

 

i see! thank you!

 

CS cold start misfire.
check everything you can ever imagine( for 2 years), except:

1. fuel pressure
2. wiring integrity
3. timing
4. compression/ leakdown
