Smart Fortwo Fuel Pump Replacement

I own a 2009 Smart Fortwo with about 66,800 miles. A few weeks ago I filled up with gas and when I returned home I had a strong gasoline smell in the garage. Doing some online research I found two possible causes. One possibility was I overfilled the tank and some gasoline entered the vapor recovery canister.

Repairing an Astron SS-25 and SS-30

I have two Astron SS-25M and two SS-30 switch mode power supplies (SMPS). A couple of years ago one of my SS-30 supplies quit with no voltage out during Field Day. Later one of my SS-25M supplies had the output voltage drop to 6 – 8 volts. About a year ago I took a look at the SS-25M to see if I could figure out what was wrong. After a little while with no success I gave up and put it away.
