Some vanagon people asked me for my opinion on the cheap JC Whitney
gauges I installed.

I'm finding the gauges useful in troubleshooting a fuel-pressure
problem.  This is the reason I bought them and they're proving
valuable.  So, I would say that my experience is positive.  Tinkering
with these types of electronics is kind of fun for me.  So, there was
entertainment value for me installing the gauges.

Here's a page I created with additional information.  There are
several pictures on the web page of the gauges and sender.
