For the first time I filled the fuel tank to the brim on my classic monowheel and the fuel smell became apparent. Tracked it down to the 2" rubber piping between the tank and the plastic fuel filler intake. Just replaced it with a piece of the piping I had for the original fuel intake from the center ceiling without the baggage mod. as I heard other builders doing that with success. Is that correct? Any other good ideas? Will check it next time I fill it up. Found the total capacity to be 67.17 litres not 70 as quoted. 9 litres was left in the Reserve.

All Europa aircraft have doors which progressively bend up over time at the rear due to the constant force of the door gas strut mechanism. Our doors fit perfectly and we do not want that fit to deteriorate. With the standard strut mechanism It is also difficult to ensure that the rear shoot bolt is correctly engaged, due to the twisting force exerted on the door by the gas strut. This modification changes the way in which the Europa provided gas strut holds the door open. The gas strut is enclosed within a pair of hinged aluminium levers as you describe. We have made a prototype and the result is most satisfactory. The door is opened and no immediate opening effect is felt until the door is about twelve inches out. The strut then gently and progressively takes over to produce a slow and even opening speed until it reaches the stop at the top. Advantages:- 1. The lever pivot point on the door is moved further away form the hinge line. Thus lower forces are involved in holding the door open. 2. The line of force exerted by the lever is almost in the same plane as the centre of gravity of the door. 3. The gas strut is totally contained within the folding levers and exerts NO FORCE IN ANY DIRECTION on the door or fuselage when the door is in the closed position. The forces that distort other Europa doors are completely removed. 4. The force that the levers exert on the door increases progressively from zero, when the door is closed, to a maximum when the door is fully open. 5. The levers are designed to reach their fully open position at about 160 degrees and are held in this position by the force in the gas strut. As a result there is no necessity to unlatch the levers to close the door. We are in the process of completing the paperwork for an application to the PFA for mod approval. If it is of any interest we can post some pictures on the Photo Share site.

I just ended up using a steel tube bent to the right shape. It is heavier than aluminum, but not as much as I expected. I would be happy to change that out for a welded tube if it were available.

Karl I just looked up polyurethane tubing on google and called one of the manufacturers. They only sold in hundreds of feet but were happy to send me a sample for nothing. I told Andy where I got it and of my tests. I don't know if he followed up. It has a slight curve and is flexible so I think it will fit fine. Tim I would suggest you do as I did and test the factory supplied rubber tube. Plug both ends with auto gas inside. It shortly smelled so bad that I had to get it out of the garage.

Cut it to match the angle required to mate up with the filler and made it about 1/2" short at both ends. I then used clear PVC flexible tubing (I got at my local Home Depot) and slid a 3" piece on each end of the tube. When I placed it in position and slid the PVC outward over the tank and fuel filler ends, it closed up the system and allowed for me to see if any fuel was in the area by looking thru the clear joint. I used the existing clamps and added the two needed with this arrangement, I've had almost no smell. I also replaced all the Europa flex piping with the local automotive "fuel injection rated" fuel lines. This would be less likely to let fuel vapor release thru the tubing. The US fuel has a lot of additives in it so I needed the best. There was a bit of conversation on this several years ago and that is when I made my change. The PVC clear tubing is easy to replace when necessary.

I bought a mandral from Wicks Aircraft it is $10 cheaper than the unit in AC Spruce. This is not a recommended tool as noted in the AC Spruce catalog it is a required tool if you are to install the fittings right. The fittings go in so tight to the hose that it really inspires confidence in the integrity of the joint. I was originally told that the 914 pumps had check valves in them. Upon obtaining them and investigating by pumping gasoline from one backwards into the other this was found not to be the case. So make sure you account for this and install some check valves. Just don't buy them from Wicks. I got a pair and they have been sitting around since 1959! (just about as old as me). These things were real relics. I now know how things were packaged befor plastic was real popular. There was no problems with Wicks taking them back and crediting me. I even gave them the opportunity to send me some newer ones but they said all of the ones they had were that old. They must have gotten a good deal from some govt surplus sale. Using this hose and fittings is indeed not cheap. Its easy to burn a C-note and just get started with the job. I was talking to Erich Trombley who just launched his plane recently about fuel systems and he has come up with a novel way to implement a fuel totalizer without having to have a flow sensor on the return line. If I understand it right He put a "T" upstream of both pump inlets and hooked the return line into the supply line. Then he put a check valve ahead of this so that the fuel can't be pumped back into the tank. He's got quite a few hours on the plane now and says the fuel burn indications are right on the money. I may try this out after getting a heads up from him after some extended usage.

Probably not a big deal as long as the latter part of your flight is not real turbulent! -----Original Message----- From: owner-europa-list-server@matronics.com [mailto:owner-europa-list-server@matronics.com]On Behalf Of Troy Maynor Subject: Re: Europa-List: Mounting fuel pumps --> Europa-List message posted by: "Troy Maynor" Subject: RE: Europa-List: Mounting fuel pumps I'd like to see a diagram of this.

When Rotax, the PFA and Europa all state that the return line should go back to the tank to prevent vapour lock, I for one take that as a strong recommendation that the return fuel should go back to the tank. Tony ________________________________ Message 21 ____________________________________ Time: 07:18:09 PM PST US Subject: RE: Europa-List: Mounting fuel pumps From: "Peter Zutrauen" --> Europa-List message posted by: "Peter Zutrauen" I wonder if the temp of the fuel in the 'short-circuit' is still kept low enough to avoid vapour-lock on hot days (versus taking the cooler fuel from the tank)? Curious, Pete -----Original Message----- From: Steve Hagar [mailto:hagargs@earthlink.net] Subject: RE: Europa-List: Mounting fuel pumps --> Europa-List message posted by: "Steve Hagar" Kevin: Yes the 303-6 hose clamps up nicely to the pump outlet. I bought a mandral from Wicks Aircraft it is $10 cheaper than the unit in AC Spruce. This is not a recommended tool as noted in the AC Spruce catalog it is a required tool if you are to install the fittings right. The fittings go in so tight to the hose that it really inspires confidence in the integrity of the joint. I was originally told that the 914 pumps had check valves in them. Upon obtaining them and investigating by pumping gasoline from one backwards into the other this was found not to be the case. So make sure you account for this and install some check valves. Just don't buy them from Wicks. I got a pair and they have been sitting around since 1959! (just about as old as me). These things were real relics. I now know how things were packaged befor plastic was real popular. There was no problems with Wicks taking them back and crediting me. I even gave them the opportunity to send me some newer ones but they said all of the ones they had were that old. They must have gotten a good deal from some govt surplus sale. Using this hose and fittings is indeed not cheap. Its easy to burn a C-note and just get started with the job. I was talking to Erich Trombley who just launched his plane recently about fuel systems and he has come up with a novel way to implement a fuel totalizer without having to have a flow sensor on the return line. If I understand it right He put a "T" upstream of both pump inlets and hooked the return line into the supply line. Then he put a check valve ahead of this so that the fuel can't be pumped back into the tank. He's got quite a few hours on the plane now and says the fuel burn indications are right on the money. I may try this out after getting a heads up from him after some extended usage.
