[Healeys] Inlet Manifold Fuel Drain Pipes

[warthodson at aol.com]

 It would seem to me that after a reasonably long drive the heat in the engine, exhaust manifold, etc would vaporize any fuel in the intake manifold. Next time you see the drips on the floor turn on you ignition switch, but do not start the engine. Listen to the fuel pump to determine that it stops pumping after a few seconds to verify that the pump & carb floats are functioning correctly. Assuming you have an original fuel pump. Also, verify that the liquid is fuel & that it is coming from the intake manifold drain tubes & not the carb float bowl overflow tube(s).Gary Hodson

Hi Harold,  I don’t think they should be draining anything on a regular basis.  I have never had anything come out of the pipes on my BT7, and I assumed they were there only to drain the inlet gallery if excessive fuel accumulated there.  Under normal operation, I did not think anything should come out, but others may have a different experience.

Though I have owned an Austin-Healey for 7+ years it has only been on the road this year and I am still learning what is normal operation. When I park the car after a reasonably long drive a few drops of unidentified hydrocarbon liquid end up on the garage floor under the inlet manifold fuel drain pipes. Is this normal operation?

  

It stands to reason there wouldn't be drain pipes unless there was a need to drain something!
