Just received, 50 ft of "Gates Green Stripe 5/8 heater hose Made in
U.S.A."  This is premium hose, O'Reilly wants 3.39/ft compared to 1.29
for standard hose.  Product info:
http://www.gates.com/brochure.cfm?brochure=925&location_id=1175

Bought this from an Amazon partner, Car Part Kings, for $1.93 plus $13
shipping.  Don't know anything about them except this purchase, shipped
FedEx and received in less than a week.  I just checked Amazon and the
price is now $14.48 plus $13 from the same partner, still 55 cents/ft.

Don't know why, but it's a screaming deal.  Listed on Amazon as Gates
28441 heater hose.
