Greetings,
I searched for my answer, but must have used unrecognizable terms!
Early TR3. I just had a 25D distributor rebuild and Jeff at Advanced recommended retaining the vacuum advance. The front carb has the adapter installed, giving me a male fitting to match there. The vacuum advance also has a male fitting to match. I purchased the female fillings from VB and they appear to not be the correct thread pitch.
Does anyone know the size and a source?
I haven't contacted Joe Curto about the carb side. Jeff hasn't responded about the distributor side.
Marv - have you got any fittings and tubes?
TIA,
 
Based on going to the TR4 distributor, I need a female fitting on both ends. I have a plastic automotive line that appears to be the correct OD, but need both fittings. if you have a complete line with female fittings on both ends, I would take that.
Completely off topic, have you ever attended the AL Jubilee Hot Air Balloon Festival in Decauter in May?
Thanks,
 
I have purchased a vacuum line kit from FLAPS and the fittings are correct in that kit. Its a coil of copper line with ferrules and nuts.
 
I found the speed aisle at O Reilly's and Autozone also have a copper oil pressure line kit that has the correct size line and fittings.
 
Thanks fellows, I'll check our O'Reilys and Autozone, we don't have Flaps down south.
Marv, we may drive the TR3 to the Balloon Jubilee, haven't been to one since Albuquerque in 1988.
 
Thanks Geo - how could that have gotten past a guy that spent 28 years in the AF, everything had an acronym?
I found a plastic oil pressure kit at Advanced Auto.
Will start another post on how to determine 11-14* before TDC with no markings on the crankshaft pully.
 
Sometimes the distributor timing does not return and the idle stays high. I put a new NOS distributor in and my idle came down much faster. Plus any air leak like throttle shafts or gaskets will not let the idle come down; sometimes people compensate the timing for the air leak also and lose performance. But again even when the stuff is working fine the idle does not come like an old school American carburetor.
