Fuel/Air gauge install (part 1)
Getting there. The case is made out of 2" schedule 20
pvc (which has to be sectioned and sqooshed a bit) to
make the internal diameter 2", otherwise you have to use
schedule 40 PVC, too bulky.
Words for the pics. Measure, cut, trim, ...

It's not wired yet and I still have to attach it to the
boost gauge (probably a bolt between the two and a saddle
bracket.

Re: Fuel/Air gauge install (part 1)
funny thing i'm working on an af gauge myself for my yj
difference is i'm building it from scratch
it will most likely be a 20-led ruler (they say 10 is not sufficient, 30
being needlessly too many)
i wonder what's "wrong" w/ my jeep -
it gets 16 mpg in winter, mostly short trips in traffic :-)
(fyi, it is a 4.0 manual)
i can't wait how the af readings will come out
if time permits it should be on the vehicle by next weekend
---
btw
i love to see my temp gauge fluctuate as i drive
i can 'see' the engine is 'alive'
when first started it worms up to about 215 deg
then the thermostat opens & temp drops to below 150
it then worms up again then drops to 170
it takes three or four cycles before the radiator temp warms up to 190 & the
gauge will cycle 190...210 deg
(remember we are talking winter temps!)
pure enjoyment!
the af gauge will be a nice addition -
it will monitor how the ecu handles various engine temp & load conditions

Looked at the schematics for a DIY air/fuel monitor and might build
one later. Just happened that a local speed-shop had this gauge in
stock and marked down.
DIY is not difficult by any means and probably about 15$ in parts.
Seen two schematics out there. One is a direct feed to the LED bar
driver ICs and the other with a smoothing amplifier circuit. Even
thought about using a basic-stamp module to build one that can record
or even give a bar-graph.
For a trick look you could use these LEDs, setting them behind
a couple pieces of ABS plastic would make a real thin bargraph.

Just a note, watch the illumination. If you can, use driver
transistors and pull the source from your instrument panel dimmer.
That way you can adjust the brightness for night and not be blinded.
