[T3] Hothe is back on all 4

[Dave Hall]

I had a NOS injector which leaked from first installation, with incredible back-fires and flames out the exhaust. After a few days it stopped doing it and didn't do it again.

Sometimes they will recover, the O-rings will absorbe gas and swell back up, 
if you let them soak in their internal gas for a week or so. This has worked 
for me at times. Go to the car once a day and turn the key ON for a week to 
keep gas in there and see if the leaks stop.  

Of course if it's the hoses, just replace the hoses.

The moral is that injectors will dry out in an unused engine just the same as 
when stored dry in your garage or basement. Better to take them out and 
store them in kerosene if you're not going to drive that engine again soon.

Yeah, it can be a pain.

BTW, I think there's more than 1 Bosch part number that are green. I know 
no one bothers with this, but go by part number, not plastic color. The Bosch 
part number is molded into the side of the plastic.
