We just got back from a 2 1/2 week trip from Atlanta to Niagara Falls, west
across the north shore of Lake Huron, and back home through Michigan.
Three days before our return the intermittent fuel pump noise that has been
plaguing me for years returned louder than ever.  According to GoWesty
here: http://www.gowesty.com/tech-article-details.php?id=115, there can be
three reasons for noise.  I've replaced the fuel tank, fuel lines, and fuel
pump.  The last suggested cause is the fuel pressure regulator.  I'd like
to quantify the pressure before replacing the gauge just to verify there is
a problem.  If I don't, I could be hundreds of mile from home before I find
out it wasn't the problem and the noise returns.  Any suggestions on a good
one to purchase?  Also, should the gauge be left on a fuel line for a quick
check or is that asking for a disaster?

Hi Steven,
I just bought a gauge from McMaster-Carr, p/n: 4066K41. It's a 0-60 psi,
made for gasoline and is 2/ 1/2" in diameter. With the engine running,
there's quite a bit of needle bounce, so I wouldn't leave it hooked up
without a snubber fitting to smooth it out. Also, it's very easy to hook
the gauge to the T-fitting, so I'd probably leave it off until I needed it.

I have been plagued with a number of new tanks that are somehow
contaminated causing the screens to get clogged up. For one customer I went
through 3 tanks and destroyed 6 pumps. Temporarily install a tee and vacuum
gauge on the pump inlet and see what you have after a drive. You'll know if
the tank is the problem.

Dennis,
From my phone.

Dennis: What type of vacuum gauge would you use on a fuel line?
