Let me know
If you need any help
Good to hear from direct from the supplier John! Thanks for hanging around here.
Based on your response, I guess it wasn't that simple... So I distinctly remember the hose being labeled on the sidewall as "Vetus 3"" hose. I assume way back in the 80's Vetus was still on the imperial measurement track. So does that mean the hose internal diameter is 75mm (3" converted to metric) or 90mm which is 3.5". I guess it might also be an internal diameter of 60mm (2.5"). Rats... now Im confused again.
I've got the hose. I just need to know what fittings will fit inside it (elbows, thru-hull, etc.).
