In order to get away from the degrading heater hose issue I has previously replaced the straight breather fitting that comes off the back of the engine with a 45 degree fitting. The plan was to just run a piece of Mil-6000 hose from that to a home made downspout and both eliminate the issue of Vans supplied non-oil worthy heater hose degrading over time as well as save myself $35 by not buying their fancy pre-bent down tube.

Try as I might, I couldn't find an appropriate diameter and wall thickness simple aluminum tube surplus here in Wichita, so I bite bullet and shelled out for vans tube. for reference, it is a 1/2" aluminum tube with a .035 wall thickness, but the upper end is stepped up for a 5/8" hose.

The 45 hose nipple I got is 1/2", as is the mil-6000 hose I'm using. What I ended up doing was cutting off the top curve on the vans pipe and just running the hose from the 45* fitting in a nice arc back and down to the vertical portion which is secured by an adel clamp to the firewall and another one to the engine mount.

I also installed the drain hose to the fuel pump and secured it to the firewall with an adel clamp. neither of these have hose clamps on them yet or the bottom end finished because the exhaust and cowl need to be fit first, but other than that they are basically done.
