CSF 2888 radiator drain petcock threads

The other option is just shoving it into that slot at the bottom of the radiator cable. I think what you're suggesting is have something that would "break away" in the event it got caught, which I'm also tossing around. In all cases though, the brass on the radiator is thin...to the point I can see it flex when I tightened in the adapter fitting and even if I try to put too tight a bend in the hose. I think even a zip tie might outlast the radiator tank in a tug of war.

The safest bet, it think, is just pushing the hose up into the cradle and letting friction hold it there, but even then it might not pull out in an emergency.

Really, the best protection here is that there would be a bumper, drag link, and the frame, that are going to hit first. It kind of goes back to what the mechanic who fixed my power steering delectable said when he ran the hoses down the outside of the box and under the frame. "If something manages to catch them up there, it would have to get through the drag link and the bumper, and if that happens, you have a bigger problem."

In reality, I could see a branch or something flexing under all of that and catching the hose but I'm probably being overly paranoid.

Had a chunk of dash 4 AN hose leftover so here’s what I came up with.

1. Fragola M10x1.5 face seal to -4AN adapter
2. (2) fragola -4AN fittings
3. -4AN to 1/8 FPT adapter
4. 1/8 MPT hex plug

Coulda cut the hose a bit shorter. It has good flex, so it should be OK.

This plug would also be an option

Nice! That plug pictured second is exactly what I used. I may modify mine a bit yet and add a full 90 degree bend - it will get the hose loop more up and out of the way behind the frame. The issue I may run into is that I won’t be able to pull the radiator out of the cradle without removing the hose at that point.

Ultimately I may end up with exactly what you have if I don’t like either of my looped options.
