Guys,
Ed said:=A0I had a fuel leak on the primary injectors. =A0
>=A0The place it was leaking from was where the hose fitting connected =A0
>=A0to the fuel rail. =A0Well, first I tighten things a bit, no good. =A0
>=A0Then I replaced the AN fitting screwed into the fuel rail thinking =A0
>=A0it has gotten scratched or warped - no good. =A0Then I ended up =A0
>=A0replacing the hose side - STILL no good. =A0Turns out one of the top =A0
>=A0O rings on one of the primary injectors was leaking, running down =A0
>=A0the rail and dripping off the fittings. Aghhhh! =A0 Two days and =A0
>=A0several fittings later, replacing the O ring solved the problem.


I just had the same problem in my 87 RX7.  The O-ring in the secondary=
 injector
was leaking just like Ed's.  When I pulled it out a piece of the O-ring was=
 missing.
I went everywhere I could think of in this small town to find a suitable=
 replacement
to no avail.  I ended up using one off an ebay spare fuel rail I had.   I=
 had a box 
of SAE O-rings but there wasn't one that would fit.  Word to the wise, make=
 sure you replace
all of the injector O-rings when rebuilding.  Make sure you put some=
 suitable lube on the 
rings before installing.  I would recommend keeping a spare set in case=
 yours leaks.  Having
to remove the intake to replace the little bugger was no fun!  Ed and I=
 could have had a fire
due to the leak---so could you!  Be careful out there, you hear?
