In fact, I've rediscovered the fun of navigating with a chart and pilotage instead of relying on the GPS. I flew down south to Belen, NM a few weeks ago and that trip is actually a little bit technical. You have the Albuquerque class C and the Double Eagle class D's to deal with. I'm transponder-less so I went around it using only the chart and landmarks to navigate my way there. I'd forgotten how enjoyable it is to do a trip the "old-fashioned-way" like that. I did cheat a little with the GPS as I approached the Belen airport, but otherwise I did it completely with the altimeter and the sectional. And never had to flddle with a fuel pump switch the whole way there and back.

I know that in a GA plane, they use a boost pump on take off and landing. I suppose that there is a reason for that, but I can think of no reason why the facet (rated at 3-5 lbs of pressure) has to be turned off when I am flying level? It certainly is not going to over power the mech. pump. I only have about 500 hours on my plane, and when I leave the airstrip almost no where that I could put down is a "good place". I am sure that the mech. pump on the HKS could supply me enough fuel to limp to somewhere better, but I can find no reason to spare the facet the function that it was designed for. Will I use less gas if I leave it off? At $28.00 I am pretty sure I could afford another one if this one went belly up. Don't get me wrong, it really doesn't matter if you turn it off after you get airborne, I am just curious as to why that is necessary.

Here are mine on the positive: Like John says it gives you another chance, it also will keep a vapor lock problem at bay when it is put near fuel supply as a pusher, a small air leak on a fuel pump pulling fuel could be a big problem but having a boost pump pushing with the same air leak will give you plenty of fuel, I know from experience where I had a small air leak that did not leak fuel but put allot of air in fuel line and turning on boost pump cleared the air bubbles. I like the idea of having a second chance more than the complicity of the extra pump in line. If your fuel filter clogs enough to not let you get full power the boost pump will give you enough you probably will and can make a safe landing. This is my take, I am sure it will get picked apart.

To the OP I'd say it's ultimately a matter of personal preference as my reasons for not liking and thus not using an electric pump (unless it's specifically called for by the installation) tend to be just matters of my own personal opinion. I personally prefer the simplest possible systems in critical areas like fuel systems because they're easier to maintain, less stuff for me to worry about in flight, easier to catch goofs on and yeild the simplest possible checklists in the plane. I.e. fan stops turning: - go to landing spot - land fan gets rough - go to landing spot - land without having to hit extra switches, etc. etc... Though I will admit that some of the terrain I've flown over in a couple of my recent trips did once or twice cause backup systems like an aux. fuel pump to pop into my mind for a moment. It did prompt me to go hug a road, which did quite enjoyable extend a flight I made the other day.

My facett is mounted below the fuel tanks and the pulse pump is mounted above the engine , HKS. The facet is wired through my master switch and is on all the time. I have never thought to check to see if the pulse pump works , I suppose it would be easy enough to check , as the mags are not wired through the master, so If i turn off the master the engine still runs. Think I'll do that about once a month from now on. Because I had a large in flight fuel leak due to a rotten fuel line that was about a year old, I do always turn on the facet and check for fuel leaks as part of my preflight. My friend in the insurance business ,once told me that it is impossible to buy enough insurance to cover every possible event , buy enough so you can feel confortable , then relax and enjoy life. I try to apply that thought to my flying.

Hart" Subject: RE: Kolb-List: Re: 582 fuel system Tom, There is another consideration. If you use a facet pump, you pressurize the whole line from the down close to the tank and up to the engine. If you are using a Mikuni pump close to the engine, all the line below the pump is sucking. If you get a leak below the Mikuni where it is the only pump, you will get bubbles and if it gets bad enough the fan stops. If the same happens to the line above the facet, the fan may keep running, but you may have fuel in the cockpit area and or spraying on the engine. Luckly, the probability of this happening is somewhere around the failure rate of the Mikuni and/or facet pump. But I believe I would find it less stressful to put the plane down with a silent engine, rather than have to turn off the engine and put it down with a smelly cockpit or an engine fire. Jack B.

(& it's cheaper than Tygon) I use Tygon only to connect from the aluminum tubing to the Bing itself, and that is easy to see and get to & change it annually. Use Gates rubber fuel line to connect from the tank & fuel pump to the aluminum tube, etc. Pad the aluminum tube throughout its runs with standoffs and short sections of rubber tubing everywhere it comes close to structure. Do it right the first time and that part of your system ought to last the life of your aircraft, with only the need to replace the rubber sections annually & inspect the rest. Fuel lines are one area where the traditional ultralight/dirt bike techniques are just not good enough.

There were always twice as many connections to have to pull tubing off of - one at the carb/fuel pump etc. and the other at the metal tubing. Also I somehow always managed to damage or bend the tubing trying to get the little pieces of line off when I changed them. I was going to try regular steel line next but just decided to go back to all tygothane. That was about 9 years ago and havn't left that method since. If I ever get an ASTM compliant motor with the fittings and such I'll definitely go with ASTM fittings and aeroquip line. That's really the right way to do it....
