Rotax 5 Year Rubber Replacement?

[Dave S]

Andy & All,

Regarding the 912ULS fuel pump from CPS.........I see two pumps listed 1) 881-360 for $98 ; and, 2) 893-110 for $205

Any Idea what the difference is?

Didn't look but I suspect the lower price is for the bare pump only and the higher price for the pump with Rotax fuel lines pre-attached.

I think the 893-110 is the new/improved pump they came out with a little while back. Maybe the other one is the old pump?

I am not looking forward to doing the hose replacement. Where did you get your hose? Are you just using automotive fuel lines? I think my annual is do in March. Ugh

ive also been concerned about the damage that the worm clamps do to the hose . the rotax website mentions an oetiker hose clamp that looks interesting , ive seen them on cars but didnt know what they were . i may have to get some and play with them

I purchased an oetiker clamp tool and oetiker hose clamps on Amazon or Ebay. I was surprised how easy they are to use, definitely 2 thumbs up.

I got stuff from all over. Ordered the water lines from the UK as they had the same metric sized gates hose for WAY cheaper than the usual sources. I took the opportunity to replace the FWF fuel lines with new custom made teflon hoses that won't need replaced again! Had Tom at TSFlightlines make them up. Makes for a very nice installation. Then I got the rest of the parts from CPS.

The 881-360 is what I ordered. It's the new fuel pump with no lines. Just comes with bare slip on fittings and new Okiter clamps. I ended up replacing the in and out fittings with AN flares and put firesleved teflon hoses on the pump.

I have been trying to find the Service Bulletin, Service Instruction that says it must be done. Anyone know the reference?
