Help with upper radiator hose selection

Greetings all,

My I6 240 to 1987 302 swap is nearly complete. Engine cranks right up, everything is working. Last issue I have is finding a hose for the radiator.

Situation is, I have a 90 degree water neck, so it exits straight up (SUM-370980). I need this to clear the march alternator pulley.
The radiator is https://smile.amazon.com/dp/B000C7QI...660910_TE_item (Spectra Performance CU433).

I was just wondering if anyone can help me narrow down a hose that may work. It basically has to have a 90 slightly after the water neck, then angle slightly toward the passenger side. The radiator mount is a slightly larger diameter as well.

My local autozone is fairly useless. I know this is a shot in the dark, but figured it couldn't hurt.

Will upload some pictures and videos soon. Once I solved some of the ignition problems, she starts up immediately. Loud as hell with open headers right now though.

Pictures may help , are you using the radiator from the 302 ? They do make some flexible style hoses if the original 302 style doesn't work

Yep, it took an hour today and I found a dusty *** flex hose buried that had the different sized ends. Napa didn't have squat, but autozone did.

Of course, once I go to FILL the radiator, it turns out the water pump weep hole started leaking, so yeah, seal must have rotted inside of it, so time for a new water pump. The fun never ends!!

UPPER RAD HOSE: 86-90 Bronco II 2.9L w/manual trans lower rad hose. This is the hose used on early Mustangs with a late model 5.0 swap. You would have to lay your eyes on it and do some measuring though.

I'll check that out, thanks. Not a huge fan of using flex hose.

The tank that was on my truck when I bought it looked similar to that one. It had a bad leak. Finally replaced it. Not to many good things have been said about those plastic tanks. Just saying.
