RE: fuel injector questions

[Erik Pullman <epullman@abrinc.com>]

Sonny,
I just installed new injectors on a 73 square.  Both the old ones and the 
new ones did not look like the picture in the Bentley manual.  The needles 
were recessed, but could be opened with a fingernail when the system was 
pressurized.  I would check them by hooking up your fuels system, and 
pressurizing everything using the wire in the back of the car (see bentley 
manual for this) or by just switching on the ignition a few time and 
running back to the engine compartment.  I've detected leaks using this 
method by carefully wiping all excess fuel from the injector tips and then 
switching the ignition on and off about 3-4 times.  This allows full 
operating pressure to build in the fuel ring.  Next, run back to the engine 
compartment and check the injections for fuel at the tips.  You can also 
press the needles in with your fingernail to make sure there is fuel in the 
works.  Good luck
Erik

Subject:	fuel injector questions

should the 'needles' really be sticking out of the injectors as shown in
Bentley?
mine don't on the one side that i've taken out (had a burst fuel hose on 
this
side and after trimming it and whatnot, it's been running like crap).
i think some stuff maybe got in there and blocked them?  but on looking in,
there doesn't seem to be anything blocking them.
can air be blown through them to clean them, or am i destined to run on two
and two half cylinders for a while?
fuel injector cleaner (techron) hasn't really done anything to help)

thanks guys
