Sohn OMP adapter install
 

I am a new member, but I have had my 8 for about two years. Here are some pics of my sohn adapter and reservoirs. It had about 25,000 miles on the reman. motor when I got it and has about 65,000 miles now. Hopefully this will help it live a little longer. I wish that I had installed one the day I got the car. I premixed one tank at 1/2 oz. per gallon to be safe until the air works its way out.

How did you make that bracket got any more man I need one. mines is haging on the cover of the fuse box. -_-

I just took some measurements and cut it out of aluminum. I had a metal shop cut the basic rectangle, but I did the trimming with a jigsaw and drilled the holes.

Props! very very clean install! im working on finding a OMP adapter. but they are just so dam expensive

There not expensive.

Oil inject. Pump Adpt

rotaryman13 - what's the part number on the oil container you used? I am guessing it's from US Plastics?
Thanks

P/N's of both containers would be nice. :)

I'd worry about that clear tubing between the oil tank and adapter though. Tygone and Tygone-like tubing (clear soft-rubbery stuff) melts easily. It also might be a golden opportunity to but some kind of filter in the line to prevent any dirt from plugging the oil nozzles.

Overall, nice looking install though!

Looks good but I have had a SOHN adapter for a while now and I would rethink using that tubing, it won't last very long.

Yes, everything I used came from usplastic.com. The oil container is a 1.5 quart item #10040 with the 2.25" vented cap item #11489. The washer tank is a .75 quart item # 12067 with the 1 5/8" vented cap item #12068. I used a 1 1/4" spade bit to drill the hole for the washer fluid pump. I installed the same oil reservoir and an OMP adapter on my 1st gen. RX-7 first to try it out, and it works well. Working good on the RX-8 so far, used about 3 oz. during the first half tank of gas with easy driving.

The tubing also came from usplastic. It is Tygothane C-210-A item #56410 and is advertised to be good up to 200 degrees F and says that it is suitable for use as fuel or lubricant lines. I hope it doesn't give out on me. I will let everyone know if I have any problems with it.

Cool, the combo looks great. That tubing should work for a bit but I had the same tubing from them and it became brittle and hard over time. Nice work.

I appreciate everyones positive comments. I hope that more people will install this mod since there is an easy place to get reservoirs. I enjoy watching rotaries live long and prosper.

Hey 9k, what kind of tubing did you use after the Tygothane became brittle?

rm13: thanks for the #'s!

Has anyone tried putting a level sensor in the oil tank? I'm thinking a simple open/closed switch installed at a low level in the tank could be put in parallel with the windshield washer level circuit and thus give a dash warning light.

One danger with that mounting location is the possibility of dumping 1 qt+ of oil onto the exhaust manifold.

I went with a black high temp silicone hose. I just use the reservoir to check the level.

Rotaryman13 - Thanks for this. Ordered my container :rock:

Clean install..................thanks for the part numbers. :)

I've got in mind to use a sensor off a scooter or motorcycle injection tank. I've got a couple, they are like a rubber plug with electrodes on a stick. Many are about the same length as that bottle is deep, but there are all different sizes. Not sure how to wire up to stock windshield bottle sensor though since you'll have 2 circuits and want having either open trigger the light. Need a better electronics person to figure out how to do that.

A caution in doing that: one probably can't easily mix sensor types. It sounds like the motorcycle sensor is a capacitive or conductive type. I'm pretty sure (I'll have to check) that the ww fluid sensor is a magnetic on/off switch.

^.................correct, it is magnetic and a simple on/off.

I'd like to know what size the hose fitting is on the adapter
measurement in mm is prefered

It uses .25 inch or 6.35mm inside diameter tubing.

Well I got around to installing the Sohn adaptor. Not an rx8 but anyhow.
Note: Before you connect the hose from the oil container to the adaptor, let some of the oil flow through. I did not and the oil would not flow. I pressurized the container a bit and had little bubbles come up before the oil started pumping

Jim Bob is right, it takes longer for the pump to pick up the oil if you don't prime the hose first. It still takes a while to get the air out of the metering lines though, which is why its important to premix a tank of fuel and put some miles on it prior to the install.

beautiful setup! sub'd for future use!! thanks op!
