[Diy_efi] Source for inexpensive fuel/oil pressure sensors?

[Daniel Nicoson]

I think the oil pressure "sender" on my Mustang costs $6.00 at NAPA.  It's
really just a variable resistor.  I'm not sure what the response curve is
but it shouldn't be too hard to figure out if you have a pressure gauge and
a pressure source.  Of course your control circuit would have to interpret
this variable resistance to be of use.

Hey all -

I'm looking for a source for inexpensive pressure transducers.  I've
seen lots in the $100-$150 range, but I'm willing to bet that they can
be had for significantly cheaper.  :)

1/8 or 1/4 NPT fitting, 5VDC (or 12VDC) power, 0-5 VDC output.  Need to
tolerate oil/fuel.  100 or 150 PSI would be perfect.

Any ideas?

Thanks,
- Brian Geddes
