fuel pressure sensor?

[Peter Lucas <lucas@xxxx>]

With all the recent attention on fuel pressure, maybe its a good time 
to ask a question that I've been saving for awhile:

As some of you know, I have been chipping away at a long-term project 
to add some modern electronics to my D. Among other things, I would 
like to do some continuous monitoring of various vehicle systems. One 
thing on my list is fuel pressure. Wouldn't it be neat (and 
informative) to continuously monitor and record the real-time 
pressure at one or more points in the fuel system? With this 
capability, a lot of the most difficult engine problem diagnoses 
would become much easier. (Imagine watching the pressure leak away 
due to a bad accumulator...)

So, I have two questions:

1) Does anybody know a source of an appropriate pressure sensor (not 
a gauge, but a sensor with an electrical or electronic output, 
analogous to the oil pressure sender)? I can handle the electronics, 
but am clueless as to where to find such a part.

2) At what point(s) of the system would it be most informative (and 
practical) to install such sensors?
