<div class="yiv8437299989MsoNormal"><span style="font-size:10.0pt;font-family:sans-serif;color:black;">If you start hearing the pump run really quickly, it can be indicative of vapor lock getting back into the fuel line... can happen at the end of long trips. It's because the fuel starts vaporizing around where the line goes into the floats, and the float jet then is no longer cutting off fuel flow because it is pushing vapor into the float bowls, which leaks out the overflow tube. As long as your car is running it should be okay, you might use more fuel than normal. Try wiring a piece of wood to the incoming fuel line - this is an old trick with Atlantics to act as a heat sink on hot days and stop vapor lock on the Atlantics which use mechanical fuel pumps.</span></div>

<div class="yiv8437299989MsoNormal"><span style="font-size:10.0pt;font-family:sans-serif;color:black;">Yesterday I took my Healey BN& out for its first good run of the season -- 75 miles of southern Oregon backroads -- with our local Rogue Euro Car Group. Everything was terrific from start to finish. Car started on the first push of the button after sitting for six weeks, ran smoothly from start to finish, never faltered in restarts, everything nominal.</span></div>

I have a standard original-spec points-style fuel pump, purchased new from Moss about 10 years ago and running without any issues every since. </span></div>
