FWIW, NAPA Gold Stripe Hose (3 ft length): NBH 607= 1 3/8 NBH 609= 1 1/2 NBH 610= 1 5/8 NBH 611= 1 3/4 NBH 612= 1 7/8 NBH 613 = 2 inch There is no NBH608 (the=is would be the logical sequence number for 1 3/8) hose. The 3 ft length of 1 3/8 hose I bought cost around $45. Have fun, SOBill Taylor sobill at aol.com
