Split fuel hose, Echo CS4000

[BeePeeAitch]

Hi, first post here, not a professional, just a garden / firewood chainsaw user. New to chainsaws so please assume a decent level of stupidity on my part.

 

Whilst investigating a fueling problem I've found two tiny splits in the fuel hose between tank and carb. This is an oooold saw, so I think it's just perished. It looks like it's about 5.5mm OD and 3mm ID hose.

 

I see there are 'Echo' listed spare parts from the US for about £10 (and a million quid shipping), but this looks like pretty standard fuel line, it's about 100mm long, and has no special contours or bends in it.

 

- Is this sort of hose available on the real from Garden Machinery places.

- Would using a suitable sized silicon hose for R/C models be a bad idea?

- Anything else on the subject that I've missed or need to know?

 

Thanks!

Ben

As long as the pipe fills the grommet in the tank wall and doesn't leak it should work whatever it is made of (if it's fuel resistant)

Hi Ben

Try looking up "Tygon Fuel Line" I use it for many saws and mowers where its cost prohibitive to find the original and you can find a way to seal the tank hole around the new line you make up . You will find it in many sizes, I use the yellow one.

Thanks both!

 

I'm leaving the grommet and little plastic union thing in the tank wall so that shouldn't be a problem.

 

Found some yellow stuff as you say, 3mm ID, 5.5 OD, £2.40 delivered. Glad I asked!

 

Thaaaanks!

Just one bit of advice …try to get the filter in the tank in its final position lying on the bottom as the Tygon isn't as flexible as the rubber lines you get. You will pick up fuel better as the tank empties.

Ok thanks, I'll test it. On my saw the filter is on a curly bit of tube and goes into a opaque plastic union / adaptor thing. That adaptor passes through a grommeted hole in the tank body. The bit of tube I'm trying to replace with the Tygon goes between the plastic union and the carb, so I'm hoping there's no effect on the filter/pickup. Maybe. hopefully. maybe not! hah. We'll see. Thanks for the extra info nonetheless.

Ahh..right .. You should be ok then if your not replacing the hole line from carb to tank filter.

The pig tail lets the filter move about and sit predominantly at the best point to pick up fuel whatever position the saw is in.
