i did it , but im having trouble with the final touches . i cant seem to find an oil tank that would be suitable , and i dont know where to mount it . so i was just wondering if anyone who's done it can lead me into the right direction with what kind of oil tank to use and where to mount it ... thanx

check your local ATV shop. Most of the 2 stroke ATV's have oil tanks on them. you might also look for an oil tank off a jet-ski or motorcycle.

I know there was a website that mentioned an adaptor for this. Does anyone have a link?

Sorry, I can't help on the tank, but checking the ATV shop sounds good.

yeah i have that adapter , its installed . all i have to do now is get an oil tank , oil line , and a place to mount it . i know im not the only one to do this mod , so i was hoping someone can tell me what they used for an oil tank and where they mounted it .

Tell me more about this modification. What is involved?

Attached you will find how I installed the OPM adapter and used the former sub sero start fluid reservoir to hold the oil.

I discovered the oil will siphon out of the tank while the car is not being used. To prevent this I installed a vacuum operated valve between the tank and the OMP adapter. This valve is nothing more that a Chevrolet purge valve. I do not remember the year or model of vehicle, but it seems to me that it was a fairly recent pick up valve.

I used an oil level sensor out of an unused oil pan to make a sensor for the two stroke oil tank. I simply wired it into the existing oil level sensor circuit.

I cut a hole in the outboard end of the tank for the sensor. I then made a plate of aluminum to sandwich the tank between two pieces of metal. The hose attaches to a double male hose barb. This barb simply presses in where the original pump was.

This is a little hard to fill, but the convenience of not having to make a new tank outweighed the drawbacks. I may eventually make a larger tank to take its place. I can manage a couple of tanks of gas before the beeper starts goin off. The tank in made in sucah a way that there is no way to get the sensor on the bottom of the tank. It sounds off when the tank is enptied halfway. A bit annoying and that is the reason for wanting to bulid a larger tank. It is a very good installation though, and except for the sensor going off too soon is working well.

I have several more detailed photos. If anyone is interested just e-mail me at copandengr@yahoo.com and I will forward them to you.
