[Alpines] Tiger Temperature Sender

[Carl McLelland]

I'm not familiar with the application so I can't be specific there, but here's
an alternative.

I'm guessing the manifold has an SAE 'pipe thread' and the sending unit has a
British pipe thread. They are close, but close only counts in horseshoes and
hand grenades. One alternative would be to plug the manifold with a brass plug
AFTER you have drilled and tapped the plug with the appropriate size British
tap.

Another solution would be to find a port in the cooling system where the
temperature sender could be threaded in but this may not be the ideal
solution.

Finally, you could call Dave Bean Engineering (209) 754-5802. Among other
things they are the authorized supplier for Lotus vintage parts. They sell
quite a variety of fitting and adapters specifically for adapting BSP to NPT
and BSP to AN; and vice versa. Dealing with Lotus racers the past 30+ years
they 'speak the language'.

Hope this helps..

  My father and I are about ready to fire up his MkIA Tiger for the first
time
  since his boss brought it to him for a clutch job...


  ... in 1973.

  One thing (among many) we are confused about is the temperature sender.

  The engine in the car (which was in the car when he bought it) is a 302 with
a
  289 intake.  There's a hole in the intake, which is where the Smiths
  temperature sender has been sitting since the engine was rebuilt in the
early
  90s. We know that the original 260's temp sender would have been in a
  T-fitting in the heater hoses.  The temp sender threads into the current in
  take (a 2BBL 289 intake) but feels pretty sloppy going in, so this is
probably
  an American-threaded 289 intake.

  Short of taking the intake off, filling the hole and retapping it for the
  Smiths gauge, what can we do?  Put a lot of teflon tape on and hope it does
  not leak?  Plug the hole and try to find this mysterious T-fitting? We'd
  prefer to keep the stock gauge as we are trying to go with all stock
gauges.
  Is it possible to find an American sender with similar resistance values?

  Cheers,
