I am trying to figure out what radiator hose people have used on their swap. I know every project is different, but I thought it might help to compile some pictures and part numbers. Can't hurt.
Here's a few part numbers for OE hoses that came on the stepvans.
Note that Cummins B Water inlets are 2 1/4"
Thermostat outlets are 1 3/4
Noting this since many hoses are stepped.
Lower radiator hose for E350 Chassis with 300-6 radiator.
GATES Part # 21812 {1 3/4" x 2 1/4" x 22 1/2" Does Not Contain Spring

I have one of these hoses, and it does have a spring.
Upper radiator hose for E350 Chassis with 300-6 radiator.
2 versions:
Vertical outlet thermostat housing:
GATES Part # 20677 {1 1/2" x 1 3/4" x 25 3/32" Does Not Contain Spring}
This one gets cut shorter and loses the "kink", but keeps the 90* bend.

Forward outlet thermostat housing:
GATES Part # 21811 {1 1/2" x 1 3/4" x 16 13/32" Does Not Contain Spring}

About 17-1/2".Upper radiator hose with forward outlet thermostat housing:
GATES Part # 21729 {1 1/2" x 1 3/4" x 32 13/16" Does Not Contain Spring}

How long is the straight part in the center?
Thanks. I was hopeing for more. I need a 1 1/2" hose with a 90* at one end and 26 1/2" to the other end.About 17-1/2".
