Gents - Many thanks for your feedback here...

OK, based on whunter's admonitions, I'm changing the Project Plan a little bit. Though my injectors are ancient, the car is now running really well with just replacement of both fuel filters... (I've had the injectors apart several times over 20 years, lots of cleaning, etc.)

So, before replacing nozzles, I'm going to start with dropping/cleaning the tank, and replacing all fuel hard lines and hoses. Hopefully this weekend?(!)

Questions (before climbing under there this weekend):
1) what is the approx total length of hard line/rubber fuel line stock in this car? Can someone give me precise stock material dimensions? (Tks, Diesel911, for the 5/16" - I may be able to find metric for all this)
2) Engine Manual indicates that the hard lines have formed fittings on the ends. Is this accurate? Or can I simply cut generally-available steel line to fabricate these?
3) Without using special offset wrench, can the strainer be removed with the tank out?
4) Gonna use a wide adjustable wrench to remove fuel sending unit...
5) Any other special tools/gotchas I'm missing?

Expecting delivery today on the fitted tank outflow and vent lines.

Many thanks again for all the inputs.

eatont999: Transmission is shifting pretty well, though I'm sure I could tweak this a bit. No, this power problem was really profound - power was dropping to near zero, and the trans was downshifting, trying to compensate.
