So the other day I was walking around autozone and out of the corner of my eye I spotted a package or coiled copper tubing. On closer inspection it was 6' of 1/8" line and came with a few compression fittings to adapt to male and female NPT fittings. This turned out to be a hookup line for sunpro mechanical pressure gauges P/N CP7584. What really caught my eye were the compression fittings that came with the line. The fittings are the exact same type as the primer fittings on the plane. Now I know what type of fittings those primer lines are...yay.
While I was at autozone I bought the line kit and also bought a couple compression splice fitting (straight through with a compression fitting on each end). The compression fittings have 5/16-24 thread for the caps and come with the compression sleve for 1/8" tube.
This evening I went about making a distribution block that will connect a single incomming hose to three outgoing ports for the copper primer line. For the outgoing ports I will tap for 5/16-24 and the incomming port will be 1/8 NPT. The distribution block will mount one of the boly holes for the oil pan.
I fabbed the distrubution block out of a solid piece of 6061-T6 that I happen to have around. I would liked to have made it from brass so I could just silver-solder the fitting in, but with the aluminum I will just to pro-seal to seal the 5/16-24 machine threads. The 1/8 NPT fitting can just use the same seallant I am using for all the NPT fitting (Perfect Seal No. 4).
I started routing the copper primer lines out to the cyl., the zip-ties are just temporary for fitting. It looks like I will be a foot short of line to finish, so I need to find some more copper line. I also need to buy one more compression fitting for the third output.
I will separate the lines with some tubing and support them with cushion clamps off some of the other engine bolts.
