IIRC that's to raise and lower the power antenna.

Here is what I did for a remote reservoir

And here is another one

Bladder-style cap for treadle-vac

Both Max Merrit and Kanter sell rebuild kits, and also rebuilt pumps with exchange.

This really helped. I thought I'd done it right the first time, and it ran very roughly, because I think actually I was off by one cylinder. I did it a second time very carefully and things smoothed out.

Speedwell Garage - Straight 8 Distributor installation

My understanding is always to torque cold and with dry threads, e.g. no anti-sieze or other lubricant. Is that correct?

Here is a picture of the tool from PNW along with their instruction page.

Yes I believe the one for the 356 engine is different - it is also sold by Max Merrit under a different part #.

Max sells two different versions of the J-4540 tool, a reproduction and what I assume are NOS. They look the same on the pictures, and don't look quite like the one I got from PNW, which isn't simply a cylinder, there is a section on one end which is relieved, so you can only put it in one way (ask me how I know).

I'll post a picture of that when I get down in the basement this weekend.

A couple of notes:

1) I noticed that Max Merrit nows sells this tool (for $30) on their website, look for

J-4540R

HYDRAULIC VALVE LIFTER GAUGE

2) Here is the website for Pacific Northwest Packards:

I checked it and it still works.

There are email addresses in the contact page.

3) If you buy a new lifter from Kanter it comes with some instructions on how to turn the new lifter itself into a gauge by disassembling it, IIRC.

The Packard Club newsletter published a series of articles on vapor lock just recently.
