Yes. It's been awhile since I did this. If I remember correctly, it is an o-ring type filter & the adapter is an o-ring to standard brake line flare fitting. I may have gotten the info from one of Lars' fuel line papers but can't remember for sure. I'm out of town at the moment but when I get back, I can try to find my source for the adapters & could take a pic or two if that would help.

Thoughts?

What thermostat housing are you using?
On my 71 the OEM hose outlet passes over the port I want to put the temp sensor.
Have you had any problems with having the sensor AFTER the thermostat instead of in the crossover?
Did you have any thermostat to sensor interference problems?

I did find a cool 1.25" spacer that VA makes with a port for the sensor. This allows the sensor to be BEFORE the thermostat.
I fear that with the hose outlet being higher the hose might kink or otherwise not fit.

Thanks

On a second look... the outlet points in the opposite direction. Can't use that one.

You could use that two port, and plug one hole. Drill an 1/8" hole in the stat, and it will read fine once warmed up.

This is an old Lars fuel line paper. I did mine this way.

I stumbled onto the adapter fittings while searching for AN to standard brake flare adapters (which are still available). Anyway, here's a pic of the adapters:



By the way, Lars has updated his fuel line paper which no longer shows the o-ring style filter. His new paper uses an AN filter.

A tip of my hat to Lars. He gave me numbers for the fittings I used.

Yeah Lars always says contact him for the newest version of his papers.
Part numbers are in the old paper if you use a filter and he used 3/8 fuel line. One of the things I like about this line is he uses the spring amour, from the listed fuel line, over the lower part of the new line to protect it from road debris.
