I've found a couple brands I like that seem well suited to my Rotax install.

www.aeromotiveinc.com
www.dymepsi.com
www.parker.con

Aeromotive has some nice 100 micron stainless steel filter options to place upstream of the fuel selector and fuel pumps.

Dyme PSI has several cool options:
- Dry break fittings (easier wing removal for transport);
- carbon PTFE hose;
- quick disconnect fittings;
- bulkhead fittings.

Parker has a high pressure Fuel Filter/Water Separator, which I think might be a more practical way to manage water in a tail dragger with a modern fuel injected engine (Rotax 916). It's called the Racor 110A.

I know none of these are aviation specific brands, but they appear to be quality and well received in the racing community. I'm hoping this crowd can talk me one way or another.

500+ hours on my aeromotive fuel filters. I use the 40 micron stainless steel filter before the fuel pumps.

Crappy answer but, "depends,"

A lot of the quality components you've listed actually beat the snot out of some supplied by OEMs, e.g. I gave away my EFII filters and replaced with an Aerolab (upstream) and an aeromotive (downstream). Each has u rating required by the pump/injectors. Each is reusable thus easily inspectable. Each has significantly more surface area -> fouling margin than the OEM supplied.

Make sure whatever you're going with exceeds that of the OEM EXCEPT the micron rating. That you want to match, not beat.

I personally would stay away from QD fittings or any other than utilize a soft seal. Suction leaks can range from a PITA to much worse. I know the aeromotive filters have options for 37 deg flare fittings.

Good luck.
 
Installed QD fittings on a removable auxiliary fuel tank installation. Was concerned about degraded fuel flow rate so upsized the fittings for that reason.
Be sure to test flow rates if you go that route.

I'm glad you mentioned that.

My thought was to step up to a 12AN dry break on 8AN lines to ensure the internal diameter didn't kill all the flow.

Same same for the inline 100 micron filter, upsizing to 12ORB fittings which gives a ton more filter surface area as a bonus.

Do you not find it restricts the flow being so fine on the suction side of the pump?

They claim very low pressure drop at much higher flow rates. I have not measured it, but have not seen any issues.

The device is pretty big, and has a lot of filter area. If you compare it to the filter Andair recommends, you'll see that it's pretty big:

Any thoughts on the Racor 110A fuel filter/water separator for use on the pressure side of the fuel system? 10 micron filter.

Seems like a decent solution to more actively strip water from fuel, rather than a gascolator relying on gravity/time.

Hi,
The gascolator we manufacture can be used on the pressure or suction side of the fuel pump. It has a PTFE coated filter which actively removes any water or dirt from the fuel allowing you to drain it from the bottom of the gascolator bowl during inspection or pre flight.

Thanks

Thanks for the info Toren!

Are you able to articulate how it differs (or doesn't) from the function of the Racor unit?

Obviously the filter micron counts are different (70 vs 10), which could be corrected with an additional inline filter.

Our unit unlike the Racor unit has a PTFE coated filter which is preventing the water from progressing anyfurther in the system, unlike the racor unit that is using multiple filters inside the unit to separate the water from the fuel. Our unit has modular fittings which allow you to fit your fuel lines direcltly to the gascolator, as with the Racor unit you will have to use 1/4npt adaptors to fit the lines. With an aero engine there is no need to filter the fuel down to 10micron. You can if you wish to but providing you keep your fuel tanks clean and dont drag the fueling nozzel through the dirt before dispening you will very rarley see any dirt in the system. With a 10micron filter what are you hoping to remove from the fuel?

Thanks

Hi Toren,
Great to see someone from Andair here - I’ve been ‘offline’ for a while & just noticed your posts. Say hi to Andy for me 😄 - Jake.

No comment on specific products, but I will say this..."aviation quality" gets thrown around a lot in advertising, and means precisely nothing unless the product actually meets the appropriate AN-MS standard. "Racing" is worse, a term with no controls at all. It is a meaningless label, so judge the product on its merits alone.

There are cases where a racing product may be good quality, but not be suitable for the desired result. Oil filters offer a good example. Many here use a Wix 51515 on their angle adapter. Wix also makes a racing version, the 51515R, same size, pretty label. The difference is flow capacity and filtration, the standard being 7 to 9 gph and 21 microns nominal, vs 28 gph and 61 microns nominal. In other words, the racing version doesn't filter as well as the standard version. It merely offers less flow restriction.

I disagree, Sir.

Aircraft that utilize "modern" electronic fuel injectors do indeed need 10u filtration; whatever the OEM calls for really but 10 is common. Relying on their integral "last chance" screens is fools play. The DOD created from the fuel pumps can easily fall into the 10u range of particulate; not to mention any that passed through the upstream 40u element.

Stick with the ratings called for by the OEM/required by the downstream componentry. That's the easiest requirement to hit when applying hardware.

If I remember correctly, Rotax specifies an 8-12 micron filter as a requirement.

Rotax specified a 10micron filter after the pump due to the fact they used a brushed motor inside the pump, as its running it breaks down and the particles are caught in the 10u filter. They also specify to use one of our high psi cracking checkvalves in parallel with the filter so when the filter is blocked the pressure form the pump opens the checkvalve and allows unfiltered fuel to flow past the filter to your engine.
We, Andair, do offer a 10u Gascolator.

Excellent info, thanks Toren!

Are you referring to Check Valve CK375-MM-14-BRP?

I'm looking at the breaking pressure of 12-17 PSI; what's to stop it from allowing unfiltered fuel to simply route through the check valve instead of the filter if the pumps are putting out 40+PSI?
