I don't like the restriction either, I still stick with rubber hoses. A -20 is closer, but the id is till a bit restrictive....and with the cost on the big sizes I'm just too tight to spend $100+ on radiator hoses!!! Some properly sized stainless tube with mandrel bends and a couple of short rubber hoses works good!
Thanks Dave. I may go that route, using some 1 1/2" polished aluminum intake tubing and rubber hose as a coupler on both ends. Yes, I saw the price of the 20AN fittings and was a little discouraged but they are reusable.

David/Dave S - Speedway has some pre bent tubing that you can consider. They have a single piece which I have recently installed as well as made up sets for flatheads that can be used. This is mine, modified a bit for the offset water neck on my Ford - and it's 1.500. I also bought a foot length of their silicone hose and the Gates shrink fit clamps - the clamps only installed on the one side so it can still be removed;

That makes a good looking set up too. I've used a the Speedway aluminum pieces a few times, especially the one's with the bung welded in to install a 2nd temp sensor on EFI engines, seems I always need one for the computer and one for the gauges and the resistance specified is always different!!!!
Oh I like those Gates clamps. Figured I would use them if I went with the conventional hoses. I just copied the link to that Speedway tubing. Thanks Dave W.
Wish I had that much room. My water pump pulley nipple is buried in my fan support (like yours), only my coolant outlet is nearly flush with the pulley from a side view. And the top coolant outlet is long, coming straight out preventing many options. At this time the hose has a hard 90 right on the outlet, going straight up and still laying against the electric fan housing.

I just use Summit stuff. I order everything I need, anything I think I need, an some of what I might need, and return anything I don't use.
Keep your cutoff wheel, the long handled cutters do the job spot on, nothing to blow out.
You can get the Teflon hose in all sizes, I keep it in stock but no good to you guys, I much prefer to use Teflon over the Rubber one, The rubber can crack with age and leaks develop and you won't spot it under the braid until i gets very bad, Teflon won't do this, also the Teflon hose is cheaper than the rubber.
The Koul clamps are nice but expensive and you don't really need them, as for cutting the hose the easiest way is with a pair of hose cutters, I've been make up hoses for the last 40 years and tried them all and the cutters do the job perfecty, you don't even need to use tape.

That sure is the right tool for that, hose lube goes along way to make the assembly of the fittings easier.
