 |
|
Just received a service bulletin from Rotax about replacement fuel pumps on the 912uls engine. When I printed it out, I learned that mechanical fuel pumps are considered to have a five year life. Oops... probably should have noticed that! Mine is a bit older.
This is a Pierburg (sp?) and I was under the impression it was bullet proof.
Am I the only one who has not been paying attention? Has everyone else with a 912 been replacing them at 5 years?
Gulp!

Dave W/Kolbers:
Did not know about the 5 year life of the Pierberg fuel
pump. However, last year my old Pierberg developed an oil
leak and I replaced it with the new recommended pump.

Spoke to Lockwood today. The Svc Bulletin starts out with the statement that all mechanical fuel pumps have a five year life span, then should be replaced. Then it goes on to describe a problem with Bing pumps.
The manual says all rubber hoses should be replaced every five years, and if the fuel lines are integrated with the pump, it should be replaced too.
Lockwood said if its an Experimental, the owner/operator makes the call
"on condition," which I take to mean, "if it ain't broke, don't fix it."
He went on to say Pierberg pumps are tough tough little muthas and he's seen them do fine well after ten years of service.
Never mind! Annual is finished, biannual flight review done, plan to go flying this weekend if the weather cooperates!
Don't worry, be happy!
