Minnesota Mooney Guy Posted January 6, 2017 Report Share Posted January 6, 2017 The Dukes boost pump failed and my A & P has selected a new Weldon Pump supplied by Aircraft Accessories of Oklahoma. The new pump charge is $1,672.59 with a $500 core reimbursement depending on the condition of the old pump. Is anyone familiar with the compatibility of these two pumps? The Weldon is a little longer than the Duke. Any advice? I am concerned that the fuel pressure will be correct with the new pump. Advice anyone? Anyone have a spare boost pump?

The Weldon is the right way to go. It is a continuous duty pump and is pretty robust. I spent a lot of time talking to the poor Weldon guy at Sun N Fun. He didn't have one of those sexy booths.My Weldon was installed in the late 90s and has been going strong since. He reassured me these pumps are built better. Also mentioned something about the impeller blades being different (but in a good way). Sent from my iPad using Tapatalk Quote Link to comment Share on other sites More sharing options...
carusoam Posted January 6, 2017 Report Share Posted January 6, 2017 The big step was continuous duty. Most likely a materials or design change in the impeller that allows for it. PP knowledge or the info I gathered reading the MS threads. Best regards, -a- Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted January 6, 2017 Report Share Posted January 6, 2017 The pump you want is the 18006-A 1 Quote Link to comment Share on other sites More sharing options...

I believe manual turbos would be the RayJay turbo-normalizing charger with a manual wastegate installed on the IO-360. Quote Link to comment Share on other sites More sharing options...

Manual wastegate with a "second throttle" knob in the cockpit to engage the turbo when you wished...typically after climbing a few thousand feet.Sent from my VS985 4G using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

I haven't heard of that The company that now rebuilds them uses seals and other parts that permit continuous duty. I'll have to look up where I had it done but is in another thread here somewhere. AEROMOTORS did the OH. Bill Quote Link to comment Share on other sites More sharing options...
