Default Dual P-Mag manifold pressure adapter

Anybody know where to get an aluminum dual manifold pressure adapter to connect two P-Mags? I have a plastic one similar to these from an auto parts store but would prefer a metal one instead.

Default same here

looking for something similar as well. If you have a manifold pressure sensor and dual pmags you need either two Ts or a 4-way adapter, and I've only been able to find plastic ones so far.

I use the push-in "Y" connectors that are used for pitot/static systems. They are behind the baffles, so the temps aren't extreme, and have worked fine for years. Also makes it really easy to disconnect and blow in a single tube to time both P-Mags simultaneously.

I had TSFlightlines alter my MP line between the #3 cylinder head and the FW with a TEE inserted in the line. He even clocked the fitting for me.
It made a nice install. Ran a seperate black hose from each PMag over to the fitting.

It sounds like there might be a small market for something like this. Maybe we can get TSFlightlines to make a few metal "T" and "Y" connectors and have them available for purchase. Something like these but in metal.

Default This is what I used -

http://www.aircraftspruce.com/catalo...?clickkey=6557

I needed 3 manifold pressure outputs, 2 for the Pmags and another for the MAP sensor.

I mounted one of the "1 IN, 4-OUT" blocks on the firewall. I installed 2 nylon elbows - one for each Pmag, screwed the MAP sensor directly into the block and plugged the unused output port.

When I check the Pmag timing, it's easy to disconnect both lines and plug them into a simple Y adapter that I keep in my tool box.

If you are going to use a line that can be pushed onto a barbed fitting, what is wrong with a nylon fitting?

Default Tom question

Are you stocking these Grainger tees ? Grainger is a little cranky to deal with.
An MAP sensor adds another T and three more failure points. A 4 port metal component as mentioned, would be ideal if anyone wants to build some. Tom built me braided tube from the prime port on #4 with two nipples for Pmags. One with three for MAP also would be perfect.
