Is there a fuel line kit available to replace internal lines in outboard engine?

I have a '91 outboard V135.

The internal fuel lines are dried and cracked; i'd like to replace them before they become a problem.

I go on the mercurypartsexpress website to find the parts number and prices to compare with off-market. The problem is, some of these fuel lines do not have a price, indicating they are not available.

Where can I find all proper tubings for my engine? I am hoping a fuel line kit exists?

Keep in mind, I am not talking about the fuel line from the tank-to-engine with a primer bulb. I am talking about the fuel lines that are inside the engine cowl that runs along from the fuel line connector->diaphragm->carbs

not sure about that engine, i always used quality fuel line from auto store, with exceptions to the lines to ea carb where i use tygon because it allows me to see if there are bubbles. Someone may have a better answer, not suggesting you follow my lead, just sharing what i have been using for a long time.

Only use tygon and clear pvc lines on gravity feed systems as it will collapse under vacuum and swell and burst under pressure as it has no reinforcment. Sorry but there is no kit for fuel lines. Try a local hose/rubber supplier or a hot rods shop for the white or grey pvc fuel line or use fuel injection line that meets the new SAE codes.

Tygon works good for low pressure. (carbs) Get it at the local snowmobile or motorcycle shop. Use zip type fuel clamps (not regular zip ties) or snapper clamps. Don't use worm clamps.

If the lines are visibly rotten, it's be a real good thing to go through the carbs and clean them. Gasket kits are about 5 bucks each (3) and base gaskets are a buck or so each. A little chit in a needle valve or main jet will burn down a cylinder in about 3 seconds at WOT in that engine.

hope it helps

Just to update this thread with what I did.

I was able to find all of the internal fuel lines at boats.net. What I keep forgetting is that my engine is so old that mercury has changed part numbers/parts for many small not usually purchased parts. I have not figured out how retailers and mercury dealers figure out the cross-walk between old part #s and new; I would love to have that kind of information instead of bothering my local mercury dealer anytime I want to buy parts.

Anyways what was great about boats.net was that they had the old part numbers that I have for my engine (at mercurypartsexpress.com and in my parts manual for my engine) and they took the responsibility determine what those parts were superseded by if applicable.
