Hi List 

I had to replace my fuel pump today and bought the new fuel pump, part number 893110.  Anyone know what the third barb is for (looks like a fuel overflow) and how it should be installed? I can't find the manual for it anywhere on the web.

Regards

Sacha

Hello Sacha.



You are correct, it is a fuel overflow if the pump fails.

Thanks Johann

Does anyone have a pointer to some installation instructions? I have asked the retailer and Rotax so far but still waiting for a response.

Hi Sacha,



Attach a hose (it can be of the clear plastic type) to your third nipple. It is a drain. Run it down and out any where you want to the edge of the cowling or opening. Do not put it out in the air stream.

If it is a drain line for gas why would you put on a clear plastic line?  Better to use an aluminum line or if you are really pressed a Tygon (yellow) plastic line.  At least with the Tygon you know the fuel will not attack it and possibly cause a collapsed line; where you will loose your venting.  Why is putting it out in the air stream a problem?

According to Rotax that can change the pressure. And yes, Rotax does want a line connected to that nipple as opposed to not attaching a hose to it (to prevent fuel from dripping down onto the hot exhaust)

Barry,

You should'nt doubt what Roger says.  He knows more about Rotax 9 series engines than anyone I know.  I use the clear plastic hose from an oxygen cannula for the overflow on my Rotax carbs.  Works great and last for years.

It's just a drain hose if the fuel pump pukes any fuel. It most likely won't happen. It doesn't hold any fuel and it should just sit there for the "just in case" moment. It's just a way to route any dumped fuel away from the engine if such an event would occur.



If you don't want to use plastic tubing then use fuel line. It doesn't matter it should stay empty.

Only a fool follows blindly.  And why would you use such an odd ball undocumented item (your oxygen cannula tubing)?  There are clearly better items for the handling of gas; approved items..  All you have to do is read AC 43-13.  

     



Roger's knowledge in not in question.  His reasoning is. Maybe Roger would explain why he recommends non approved item for handling gas.

I just read Roger's response:  " It's just a drain hose if the fuel pump pukes any fuel. It most likely won't happen. It doesn't hold any fuel and it should just sit there for the "just in case" moment. It's just a way to route any dumped fuel away from the engine if such an event would occur."  

 This is acceptable to you!  If it is so benign why not use a paper straw?  It would be so much easier to use a proper item that is fuel approved.  It is not like it is expensive or difficult to obtain.

Barry, Here's Roger's original recommendation:"Attach a hose (it can be of the clear plastic type) to your third nipple. It is a drain. Run it down and out any where you want to the edge of the cowling or opening. Do not put it out in the air stream."

 I don't see where his recommendation is to use something that's completely incompatible with gasoline. Plastic takes in a lot of territory. I've attached McMaster Carr's Chemical Compatibility chart for just one type that I picked out, PVC. Some is recommended for gasoline, some isn't, and this chart is for tubing that will hold gasoline, not just sit there holding nothing but air, waiting for some gas to run through it.

 Pete didn't specify anything either, other oxygen system cannula tubing. No chemical formulation. Again, takes in a lot of territory.

How exactly is your wise council any better? Use aluminum you say. What alloy? What hardness? Work hardened? Heat treated? WTF?

 My ex-wife liked to leap to conclusions and start running her mouth. That was the primary reason I booted her fat butt out the door.
