Greetings Fellow Enthusiasts!

I had a recent incident with my '98 40 HP Merc\Force caused a loose ty-rap at the carb inlet. Is there any reason why ty-raps are used on all the fuel lines? Would one benefit by replacing them with small metal hose clamps??

Thanks,
-Nels

I don't know of any reason they are used other than they are easier to get into tight spots with. I have SS hoseclamps on mine and they work fine. I'm sure someone will come on here and tell me my engine is going to catch on fire or something, but I've been doing it with clamps for years with no trouble:)

Nothing wrong with either! Stainless worm clamps do well if you take care to buy ALL stainless. Some have a stainless band with a regular plated steel screw and are still described as stainless on the package. It is also easy to get them too tight and cut into the hose. That said, I have a couple of engines that have had them for years with no problems.

Elecrical wraps are faster to put on and can be adequately tightened by "rolling " the free end over the catch with a pliers OR (preferable) using a tightening tool. They can not be overtightened as they will slip/strip, and are easy to remove--just cut the catch. They are so cheap that desrtoying them to disassemble the lines is the way to go--even if you do it a lot. They will not cut the fuel lines and are small enough that you can double wrap if you feel insecure, assuming you have a narrow enough width band.

Personally: I never use hose clamps any more. Any engine I work on gets the plastic ties. All the engine manufacturers are using them so they can't be too prone to failure. I haven't yet had a fuel line leak or pop off a fitting either. So maybe you were just lucky. Replace with whicever type you fell comfortable with and don't worry.

Keep in mind that not all ty-wraps are rated equally! Most of the clear plastic ones will fail eventually, but uv rays will promote their failure. Black ones will last longer. And if you order from a good electronics shop, and not the big box stores, you can find a higher quality brand.
