[T3] Fuel pump rod

[Brion Sabbatino]

This is all great information. I will look for the proper fuel pump and get some beetle electromagnetic valves. I suppose any VW ones will do? They hook up to the ignition switch side terminal of the coil, so that is easy enough. I did not realize they simply replaced the idle jet. Strange how none of mine have one.

Off to have the tires balanced today. It is a one-hundred mile round trip. There are still some items to be sorted out. They PO owner replaced the fuel filler hose and did not install the smaller inner rubber sleeves. Repair the clock, get the fuel gauge to read over 1/2 full. Purchase wiper blades.

Replaced the hood and rear hatch rubber with WCM products yesterday. Should be a quieter ride now.

Thank you all.

For a while I was regularly parking my daily driver 63 Bug in a hilly area without giving it a second thought.  Once, parked nose up with a full tank of gas, I came to my car the next morning and found that it was hydrolocked.  When I turned the engine in reverse a bit, fuel began to drip out of the muffler.  Not a fun day.  Now I go out of my way to park on level surfaces, or at least nose down.

The part number for the rebuild kit is 311 198 555.  If you have trouble finding a rebuild kit (beware -- although some parts are shared with T1s, the diaphragm assembly is T3-only), you might try contacting Ed Fall (http://www.vintagewerks.com/).  I don't see it listed on his website, but he was at one point providing a fuel pump diaphragm replacement service.
