 Posted: Mon Nov 15, 2010 10:22 am Post subject: Is Facet/Purolator 12S Model 40106 OK on Rotax 912 |
 |

List,
I have a Kitfox IV Rotax 912 UL, w/ a Purolator/Facet 40106 pump installed down by the header tank. It specs 4-7 PSI. I'm guessing w/ a foot or so of lift to the engine driven fuel pump, 6 psi is getting up to the old Pierburg 7 20 971 55 fuel pump. after the p/n is "7/124" any translation to the last 4 numbers?
Is this ok or should I go down to the 40105 model pump that is more of a 2.5 to 4 PSI pump?
I only run the electric pump to fill the carbs before start and check for function.
Reason for asking is AD: FAA AD-2010-18-14. The TCDS for the engine lists my Pierburg pump or the Rotax P/N 996590, which do not seem to have an AD against them and are NOT in the above AD note.
Looking at the Lockwood parts list, it says for 892 230 (Subject to the AD) USE 892 542 (at) $176.23.
So, to sum up- Can the old Pierburg 720 971 55 pump be used safely (This is on an Exp/Am Build, but I'm trying to get the background) and does the 40106 elec pump at 4-6 PSI work safely w/ the Pierburg pump?
If the Pierburg fails, is the 40106 a good feed to the dual Bing 64s or will it cause venting/overflow?
Thanks!

Get the 40105. I have it on both my aircraft. Both have a long lift to the pneumatic pump so I run the pump all the time. It doesn't over power the float needle on either the 54 or 64 carbs.

Hi Rich,
The pumps that go to 6-7 psi is too much. Get the other pump at 2.5 - 4 psi. This is where the engine normally runs (3.1-4.5). Running 6-7 psi will over pressure and flood the carbs. Your engine only needs 2.2 to run. If you have a high wing then it could be lower at the pump with a little help from gravity in an emergency.

Thanks! Ordered a 40105 for $40 shipped from A/C Spruce, none locally available at the auto parts stores.
