Oil injection lines and questions

[prairieboy]

I have a bunch of clear fuel line lying around from a previous project and was wondering if I could use them for my oil injection lines.

Also, my reservoir is 3/4 full. Do I have to drain it first? What about the oil filter. Is there a specific filter for oil or can you use something else.

Lastly, bleeding the oil line after replacing. I've read both arguments about having to versus just cranking for short bursts.

Thanks in advance!

If you don't know EXACTLY what they are made of... then DO NOT use them. You need something that is known to be oil/solvent/Chem stable. I personally like Tygon. I've been using it for a long time for oil hoses with no issues.

The oil filter is kind of low restriction for what it is. Just get the right one from seadoo (or other PWC) It should be around $8.

No... you do not have to drain the tank, unless you are getting rid of the oil in the tank. I would rig up the new feed hose, and pinch the end, and then quickly swap them at the tank. You may spill a little, but you should be able to do it with minimal mess.

Not sue what you are asking here. I think you left part of the "Vs" thought out. But... open the bleed screw on the pump, and fill the feed hose. Then... put a little oil down each carb (an ounce or so) and then start the engine, and hold the pump arm to full. It will take about 10~15 seconds to push the oil up the small hoses, and into the engine. Cranking the engine won't do a dam thing. You need the RPM of an out of water idle. (about 3000 rpm)

Thanks Doc!

The thing with the clear line is that it is fuel line. I know that for a fact it is cause I have the receipt for it still. So do you think it's ok for oil supply?

It may be. Don't know, since I didn't buy it. Normally... if it's OK for gas... it's OK for oil. But not all are. I know there are a few types of vinyl that are OK for gas (not great since it gets hard) but is a no-no for Kerosene, Diesel, or some oils.

Get the tygon line. Its like a yellow tint. the real tygon has their name on it and they do sell aftermarket tygon that works also. It is oil safe. There is not many aftermarket hoses that are flexible that hold up to oil. The cheap stuff will work for a short time get spongy and bye bye engine. The line is roughly $2 a foot. Cheap is you buy a box and you are set are the rest of your life.The most important lines are the little ones from the pump to engine. Those are the weak link. In the end you are talking like $15-$20 for the proper hoses.
