So, I hooked up my brand new HF fuel pressure gauge (thanks for the tip at $19).
Sure enough, starts, runs fine for a minute, starts missing, fuel pressure drops, engine dies as pressure gets under 20lbs. Wait a minute, engine starts back up, repeat cycle.

All of a sudden, I see a spray of fuel coming from injector #1. Can't really tell if it is coming from the short hose from fuel rail to injector or the injector seal. I assume that I caused this problem while moving the fuel rail around when hooking up the pressure gauge to the test port. The only way to make it leak is to put everything back, but then there is too much stuff in the way to see where it is leaking.

The injectors have been replaced by me in the past, but it has been over 15 years. Should I just bite the bullet and replace all 4? Can I get mine rebuilt (do they replace the hoses?) I found injectors reman'd by Standard Motor Products for $35.79 ea on Rockauto - are these any good, or junk?

Thanks

Mine are green tops, with 0 280 150 112 stamped on the edge. These are in a 1.8 L Jet. Are all green tops for 2.0? Do I have the wrong injectors?

.
L jet and D jet injectors use a different electrical connector plug. L jet are either turquose or grey.
I have not ran the number to check if they are correct.
You can not rebuild an injector. They are just cleaned and tested. The hoses can be replaced but if the body is leaking they are junk

@SteveL


they can also be junk if the pintles suffer micro corrosion.
got mine to go again after cleaning. tested - worked fine.
but they just wouldn't work once back in car. basically jambed shut again after a short period post cleaning and before i could get them into the engine again.
this was after they had sat around dormant in the car for 16 years.

when i bought the car back in 89 it was a very similar situation.
the car had been dormant then with its first owner for about 5 years.
some of the injectors were leaking and one or two were jambed due to internal corrosion.
