(I don't think I have a fuel problem, but when I'm reading about my car,
curiosity rears its head and I have questions.)

How come so many cars have a nipple on the fuel rail with which to test
fuel pressure, but 2005 3.3L Toyotas etc. make one insert a T-connector,
iiuc underneath the rear seat or just above the gas tank. And IIUC,
then you have to remove the T-connector when you're done. Much harder
to get to, and both chores are so much more effort than using a nipple
on the fuel rail.

Toyota is not usually inconvenient, afaict, so what is going on here?



Oh, and why does the shop manual not include pictures? It only has
outline sketches (not even detailed sketches)? I've had Pontiacs and
Chryslers and I bought the shop manual for my brother's Ford, iow all of
the Big Three, and every one had much more informative manuals than
either of my Toyotas'.

And there is constant reference to toyota-specific test equipment etc.

Basically, I can't tell a thing from the shop manual and have to rely on
youtube videos and on webpages. Whereas with American cars, the shop
manual was all I needed to fix them.


Is it that Toyota manuals are designed only for the mechanic and not for
anyone without a lot of experience?

Are all Japanese shop manuals like Toyota's?

Is this an example of foreigners with an elitist social hierarchy, or at
least a strict one, unlike America where there is a belief that anyone
can learn to do anything? --- I've exaggerated the American part
some, but I do seriously intend the general nature of the question.
