Richard Sohn Metering Pump Adapter Install
So a while back, I picked up an OMP adapter from Richard Sohn. http://www.rotaryaviation.com/oil_in...p_adaptors.htm
You will have to contact him directly at:
Richard Sohn PCV Technologies, Inc. 8029 HWY 1087, DeFuniak Springs, FL 32433. Tel/Fax(850)834-4905 email: RES12@fairpoint.net
Now for those that don't know, this device allows you to use a separate reservoir as a source of the oil for the OMP. This allows you to use 2 stroke oil instead of dirty engine oil to inject.
For a reservoir, I chose a Yamaha Razz/Riva oil tank. ( http://motors.shop.ebay.com/_Motorcy...1QQ_trksidZm38 ) It was cheap, the size I wanted, and when mounted would look somewhat stock. In addition, it was designed to hold 2 stroke oil and thus would not be dissolved like some plastic containers. The tank also had a level sensor. Its operation allowed me to wire it in parallel to the stock oil level light. This way, if either the sump or the tank runs dry, the warning buzzer and dash oil light will illuminate.
To mount the tank, I made a bracket out of sheet aluminum. It turned out nicely and is very strong. The hose I chose is polyurethane as it is oil resistant, but still clear, allowing me to inspect the line for air bubbles.
I also ordered a OMP rebuild kit from Lowe Performance ( http://www.loweperformance.com/ ) It uses Viton o-rings, and as such will last longer than the stock rings. Correspondence with the company took a while, but in the end was worth it.
Now I am just waiting on a second OMP gasket from Mazda. They have taken two months to try to get one in

Excellent mod Sgt. I was wondering about doing this sometime. Three questions.
How do the two pump pieces actually fit together? I've seen these before and assumed they bolt one on the other and one pumps from the reservoir and the other pumps up to the carb. Maybe a pict of the install would clear it all up for me.
Do the pumps utilize the existing OMP linkage to control the output of these or are they constant?
Last question where did you get the clear poly hose?
Thanks for posting this up.

In my first picture there is both a 12A and a 13B adapter. The adapter goes in between the front cover and the OMP.
The stock linkage is maintained.
I got the clear hose at a local industrial supply shop.

Awesome thread.
Good to see Lowe's site is back up after all these years. I still prefer calling them though, it seems to be the best way to get them moving.
I've been wanting to do this for a while, it's still on my to-do list. Thanks for the great post. It would be cool if you could snap a pic or two of the adapter installed

I have this same kit. I need to get off my *** and install it. Ive got a stainless oil can with a level tube. Its nice, but I actually think I like your tank better. Looks more stock and clean.
Nice work.
What premix are you using? I bought a case of Idemitsu from Mazdatrix.
Also, when I ordered my OMP rebuild kit from Lowes I just told them i needed another OMP gasket and they added it to the order. For like $2 or something.
I need to get another rebuild kit from them and then I am ready to go. The OMP I rebuilt I accidently sold with my old engine and the seller is taking their ever loving time getting it back to me, over a year.

Very nice install fox, I'm interested to see how it all works out (I'm sure just fine) as I was planning on doing this on my cars as well.
Edit: just looked at the site again and it looks like the 12a adapter isnt listed anymore, bummer...

Didnt I buy my RA OMP adapter from you wrxracer55? I swear I did. Its funny you bought another one. Mine's been working like a champ for a long time. Much easier than dealing with letting the fuel run real low and then putting a certain amount of premix in. This way you just check the 2 stroke reservoir and fill up the tank, or simply put 10 bucks in. Whatever you want to do - no need for doing the math and worrying about overfilling the premix in the gas tank.
