Stainless Steel Hose Clamps on Fuel Lines
Posted: Wed Apr 13, 2022 10:19 am
Is there any reason NOT to replace wire-tie clamps [perhaps means nylon cable ties] with stainless steel hose clamp on fuel hoses?
BACKSTORY: Preparing to launch my Sport 13 I noticed fuel stains and spilled fuel on the deck. The fuel was coming from the primer bulb connections to the fuel hose. I was surprised because our local Mercury shop replaced the fuel hose than a year ago during some repair work.
Close examination revealed the leak was on the tank side of the fuel hose. Two things appear to have been contributory. First, the line is clamped to the bulb by a wire-tie and second, the tank was under pressure caused by fuel vapors.
I released the tank pressure and the leak stopped. After cleaning the spilled fuel I loosened the tank fill cap to prevent any tank pressure from building. The boat is stored in our garage which can become hot even during cool weather. The outside temperature was about 70-degrees-F. The garage temperature was about 83-degrees-F. I believe that the tank pressure relief threshold is too high for the fuel line to withstand. Either the tank pressure relief or the fuel line is defective. Due to the wire-tie connection my money is on a defective fuel line.
