Brian,
I that regard, I think that you are right.
On the other hand, I've never had a fuel pump fail either. Is there a verifiable history of this on M-14P's?

I have only flown (front seat) three different ones. All leaked in either the prime or fuel pump position. I suspect that if you really analyzed the hand-plunger type pump you would find it not particularly robust.
Regardless, does anyone here really think they can keep an M14P running on that primer pump used as an aux fuel pump? Really? At least I think you have enough volume with the wobble pump in the CJ to keep it going but I am not nearly as convinced that one could keep a Yak52 in the air on the "aux" pump.

Roger,
I like the idea as it adds a margin of safety. When flying certificated singles and twins, the boost pump comes on during takeoff and approach. Got used to the idea and seems like a reasonable practice if Barry's set-up can be used in the same way.

When it comes to systems a lot of stuff on aircraft is, uh, suboptimal. No, there doesn't seem to be a history of failure. But I am personally averse to any sort of single-point-of-failure where an alternative exists. I have contemplated how I would switch hands to fly with my left and manage engine power by pumping, or not, with my right hand. I don't like the idea.

Hello,
we mounted two Pierburg fuel pumps under the passenger floor in our 18 T after experiencing severe loss of fuel pressure in warm weather during the take-off run. And you just donĀ“t want to deal with that once again. I have to add that we run the Yak on leadfree auto fuel from the beginning for 5 years now - as most of you would do facing the price of avgas in Europe. With these pumps plus a one-way valve feeding into the standard fuel line pressure stays above 0.5 bar in all conditions and this is only used for pressurizing the carb before engine start and for take-off. I canĀ“t see how to manage an electric primer pump replacement with good control so we keep the manual pump for our starting technique. No big deal to keep that sealed as the critical parts can be accessed from within the cockpit. It is true that the action of the plunger is not really smooth with an o-ring acting on the steel plunger in non lubricating gasoline. So we made up a set of seals from teflon and nylon/polyamide plus o-rings as elastics - no more problems.
I can think of a setup feeding fuel into the primer line going into the induction chamber in case of a carburettor failure. All youĀ“d need is a T fitting and an electric/mechanic valve and some flow-limiting valve which you set up on the ground for about half power to get you to an airfield in emergency.
I remember a story when the seal between the oil pump and the fuel pump failed . The consequence was that the oil pump fed oil through the fuel pump to the carb at 2-3 bar and the pilot was lucky to make it to the airfield - just - with minimal power - and oil - left.
Cheers
Vic

The vane type aircraft engine driven fuel pump is indeed a very reliable unit. But, like any other mechanical device, they have been known to fail on occasion.
It is good practice to overhaul or replace it at the normal engine TBO even if the engine continues in service beyond that.
Of course about the worst time for a primary fuel pump failure would be right after take-off.
Both the Yak and the CJ have the emergency fuel supply on the wrong side of the cockpit. Both the location and the pump type in the Yak virtually guarantee a bad outcome.
The CJ is better but a good outcome would be a function of luck and awesome dexterity.
For me it will be an elec. aux. pump as it was in my Harvard even though the hand wobble pump was correctly located for the left hand. Always on for take-off and landing. A primary pump failure on T.O. would not be noticed until you kill the aux. pump at circuit altitude. Ho-Hum - turn it back on and land!

When I put the M-14p in my CJ, I had a big concern about the wobble pump and my arm keeping up with running the M-14. I replaced the wobble pump with a 24v Facet electric pump. I had a local machine shop make up the fitting conversion I needed. One day right after takeoff, I got smoke in the cockpit! Big time smoke, acrid and deadly. I switch off master switch, alternator and canopy open than made a hard turn 180 for the field. By the time I landed (:45 seconds) most of the smoke had cleared. What I found was the Facet pump had an internal short (I donāt how) that burned though its casing.
All of us here on the list, have ideas (great ones) that are colored by our life experiences. We tend to judge new ideas by those experiences. Old farts like old things (sometimes), and old farts-to-be will be more accepting of new stuff of the ānew ageā. This is my perspective, I am a cheap SOB. If I can fix it with a āOā ring, I will. If there aināt no more of them there parts, Iāll replace it with something new. I like Barryās mod, but I hate depending of electricity for my fuel. Once I kept the M-14 running with just the primer. Now its like an old friend, soul mate and guardian angel to me. (Well I guess thatās a little over the top). But when the parts wear out, his system will most likely get put in.

I suspect you are attempting to cast aspersions but I will treat your question as serious.
No, I am not an expert on absolutely everything. I am just more familiar with more parts of physics and engineering than most people I have met. I also tend to test things by experiment. I do a lot of test flying of airplanes to see what they really do, not what other people tell me that they do. I tend not to trust "conventional wisdom" until I can understand its origin.
For example, I was told from a very early age that one should never turn back to the runway after an engine failure on upwind. OTOH, the turn-back to a downwind landing is normal in a glider after a rope break above a certain altitude. I wondered why it isn't the same with a powered plane. So I went out and experimented. I did several attempts in different aircraft and determined that the turn-back is a viable maneuver in some aircraft from some altitudes but not viable in other aircraft. These included actual turn-back to a dead-stick landing. It is one thing to do it at altitude but it is also very helpful to do for real where the visual cues are different.
In addition, one of the things I am really good at is systems analysis. I have an uncanny ability to look at a system a quickly deduce its points of weakness and the ramifications of failure of various components. I tend to then go about redesigning systems in aircraft I own to eliminate single-points-of-failure. FWIW, the CJ6A presents an AMAZING number of areas for improvement. I have never owned a Yak52 but suspect that its systems would respond to similar analysis.
I guess you weren't around here 10 years ago.

Here is what I did in my CJ. I placed the fuel pump and the primer solenoid in the forward, right hand lower access area. I removed all lines out of the cockpit to include the primer and wobble pump. Now the complete fuel system is operated by a single switch on the right hand panel. This switch activates both the prime and fuel pump function. No need to pull the prop through when priming now. As I turn over the engine I hit the momentary primer and the engine starts every time. If needed I can hit the electric pump with the same switch that will lock in position with a center off. You can see the switch in the picture. It is the guarded switch in the yellow stripped area with two lights that indicate primer, boost pump, or primer and boost pump. Just another way to skin the cat..

Subject: Re: Re: Electric Fuel Pump
Here is what I did in my CJ. I placed the fuel pump and the primer solenoid in the forward, right hand lower access area. I removed all lines out of the cockpit to include the primer and wobble pump. Now the complete fuel system is operated by a single switch on the right hand panel. This switch activates both the prime and fuel pump function. No need to pull the prop through when priming now. As I turn over the engine I hit the momentary primer and the engine starts every time. If needed I can hit the electric pump with the same switch that will lock in position with a center off. You can see the switch in the picture. It is the guarded switch in the yellow stripped area with two lights that indicate primer, boost pump, or primer and boost pump. Just another way to skin the cat..
