Re: 2000 TJ 4.0L fuel injectors
You of course can always add an anti-drainback valve anywhere in the
feed line, which would be as good of a fix as replacing the OE
anti-drainback valve would be. As said already, I'd bet big $$$ your
problem is nothing more than a leaky antidrainback valve.

Thanks, everyone.
The injectors are due for cleaning, so I'll have that done. The
anti-drainback valve Jerry mentioned sounds like something I can live
with until the fuel pump fails.
Again, thanks for help!

Re: 2000 TJ 4.0L fuel injectors
Matt, I really doubt you're having ANY fuel injector problems and I even
more strongly doubt they need cleaning. Today's injectors with todays
fuels that ALL contain fuel injector cleaners keep them pretty darned
clean. They just don't wear out this quickly, 110,000 miles is not a
lot of miles at all. Mine have 160K miles on them and I know plenty
with over 220K miles on them. Just trying to save you a bit of $$$ and
time.
