EXCELLENT advice.  May I also suggest you add to your Leveloff, Cruise, and pre-Descent Checklists the following:  "Observe The Holyshit Line."

 

The Holyshit Line is a 1/4" line painted on your fuselage tank gauge vertical stick in Day-Glo Orange at the lowest observable point on the stick.  When the Day-Glow disappears, you have just discovered the reason for the name. 

 

The Emergency Procedure for this condition is as follows:

 

1.  Land ASAP

 

2.  Give the ship to an A&P to discover the reasons for depletion of the header tank.

 

3.  Find Chardonnay.

Ed,

 

An electric backup fuel pump is part of the 30 gallon tank mod.  But why would you bother?  Fred built the Coupes with a better system – a 30-45 minute gravity fed reserve system.

 

If you drain your nose tank into a very clean fuel can then fill the nose tank one gallon at a time, you may like the results.  On my plane, there were three gallons in the tank when the float gauge was at the bottom.  The gauge was only measuring the top three gallons of the tank.

 

So, if I have the diligence I think I’d *better* have, I’d have 4.5 gallons plus left when I see that the gauge is heading down.  At maximum range, that’s a good 75 miles.

 

Just make the wire gauge a regular part of your scan and you’ll be safer than most other low-wing planes out there.

Does anyone have an approved 337 for replacement of the mechanical pump with an electric pump like the 0-200 STC uses?

I'm pretty sure I do.

These pumps are getting pretty expensive. It's my understanding that the source for rebuilt pumps is drying up and only new are available.

This is maybe a semantic distinction, but rebuilt pumps are readily available.  The are "like new" and very expensive, though.  (New pumps are even more expensive.)  What has dried up is the source of parts to rebuild your own.  All rebuilds come from the factory...

I haven't had to replace one recently so I don't know this first hand.
 

Developing a separate STC for this pump setup on a C75/85 is on the list of things to do.  When I get a round tuit....
