Both have beenused sucessfuuly. Your choice. I don't have any experience withfiberglass but I believe Brian Kenny has and I think he used polyester.Tom Bowdler is also using a nose tank. He used galvanized steel and hadit soldered. My engine is also a corvair, but Iremoved the mech. pump.Since I've used the center section (3 piece wing), There is plenty offlow if you use 3/8" OD aluminum fuel line. I measured the flow with thetail 3 feet below the ground level to simulate take-of attitute at 2Min.and 18 seconds.

Order just enough, and no more.Seriously, there is no way anyone can tell you. For one thing, there aremany different sizes required, and vastly different amounts depending onwhich landing gear and which engine you are using. Whatever you calculate,double it. Steel is cheap - shipping it is expensive, and screwing up apart and then having to wait for more steel to arrive because you orderedjust enough is very frustrating.Many of the parts are made of .090" steel 1" wide or 3/4" wide. You can buy4130 strips that are slit-sawn to those widths and that vastly simplifiescutting the parts.Jack PhillipsNX899JPRaleigh, NC-----Original Message-----

If you don't live too rural, you may be able to find a metals supplier nearby.It doesn't all have to come from AC Spruce or Wicks. Usually cheaper too. I founda great source in St. Louis, MO, Shapiro Metals on Natural Bridge. They recycle,deal in used materials and also have a great selection of 4130 sheet andtube and 6061 & 2024 aluminum.If you live out in farm country, check with your local tractor and farm equipmentshop for materials. If they have it, they can probably tell you where to findit. Counting shipping, I save over half the price compared to Spruce or Wicks, andI can pop in whenever I need to restock.

Since the Stromberg has no effective mixture control, a recommended way to do engineAND fuel shutoff is to have a cable operated valve close to the engine.The theory is that if you use just the ignition to shut down the engine, theunburned fuel can cause flooding/hard starting issues during a quick restart.Also, the float seats can be a source of leaks so an easily usable fuel shutoffof some kind is almost mandatory. A fuel shutoff at the wing tank is alsoa very good idea just in case something catches fire. That eliminates gas asa source of fuel and also isolates the fuel in case of a forced landing. Hookingboth valves to one cockpit control is going to be my choice.Dave AldrichRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: fuel tanks

Both fuel tank locations have worked fine. Here's why I went with a wingtank and like it.1. The fuel is farther from the hot engine and electrics in most"unplanned attitudes" such as upside down or on it's nose, or in case of anengine fire.2. I have heard of too low fuel head pressure/fuel starvation issueswith fuselage tanks, but not with wing tanks. If you're building a big fusetank, it can be tricky to design it so you get the head pressure you need.It can certainly be done, just watch it in all attitudes.3. Fuel overhead or fuel in my lap can both be bad situations, but it'sall dependent on the incident and there's probably no way to foresee.4. zero CG shift from full to empty.5. I like the storage area up front.In view of WW's accident and the very real potential for forward wingdisplacement during a sudden stop, I strongly recommend flexible fuel linesto the tank. When 799B went over, the wing DID move forward about threeinches and my hard lines held fine, but when I rebuilt her, I was sure touse flexible lines.There are certainly pros for fuselage tanks too, but these are the reasons Iwent with a wing tank.Douwe________________________________________________________________________________Subject: Pietenpol-List: Re: fuel tanks

I can add to several of Douwe's points (his #1 and #2)-1. My airplane has been upside-down. Carb ice, power loss, precautionary off-fieldlanding on rough terrain... a weld broke on the landing gear leg and it wentover on its nose and onto its back. There was no fire, although there wassome fuel loss through the vent on the fuel tank cap. What I'd like to emphasizewith this is the point that William makes about providing some flexure inthe fuel lines and for making the cabane brace connection rigid rather than adjustableonce you've set the wing angle. Examine the photo of my cabane bracesafter the roll-over and you'll see why:http://www.flysquirrel.net/piets/incident/PB130010.JPG2. The final couple of gallons (about 2.5) in my 16 gallon tank are unusable inthe 3-point or climb attitude. I demonstrated that fact on a x-c where I landedwith about that amount of fuel in the tank and as soon as I eased the taildown, the engine quit. It's simple physics and geometry... liquid doesn't liketo flow uphill ;o) Examine a side shot of my engine, like this one:http://www.flysquirrel.net/piets/engine ... JPGPicture where the carb float bowl is relative to the bottom of the fuel tank (aninch or two above the horizontal seam in the firewall). So Mikee is right...I don't fly it down into that last 1/4 tank or so.Two more things and I'm done. First, that seam in my firewall was intended tomake the bottom portion removable to provide access to the underside of the fueltank, the front rudder pedals, and anything else up in the forward cockpit.Unfortunately, I forgot about the engine mount bolting on and being in the way,so it's not removable. Sometimes good ideas aren't ;o) Second, I have neverfueled my airplane without using a ladder. I like to be able to see downinto the fuel tank because it's too easy to flood the tank and cowling if I letit get up to the top. It sometimes happens even when I can see down into thetank. So don't think that using a nose tank will eliminate the usefulness ofa ladder for fueling, unless you're a lot taller than I am (5'-9" in high heels).--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Adding Tank to Wing

It's been mentioned a bit in the past, but surprisingly hasn't come up in theserecent discussions at all.About point #2. Dick put a 4 gal (or so) header tank in the nose of 2RN. Hisreasoning was (and I'm a big fan, think it's a great idea) that it prevents prettymuch any chance of the engine quitting because of sloshing in the relativelywide and flat wing tank. At 4 gal, it's an hour reserve of fuel if necessary.I got to thinking about it, I've got a shutoff right outside the cockpit wherethe fuel exits the wing tank. If I were to lose my engine and was in the midstof deadsticking it in, wouldn't take but a fraction of a second to reach upand close that, which would be even more insurance against free flowing fuel inthe event of a fuel line rupture due to wing displacement.Like everything, it's a compromise. It does complicate the fuel piping somewhat.However, as 2RN needed some nose weight due to the relatively light A65, thatwas absorbed. Just more food for thought.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 26 Mar 2014 17:47:45 -0700 (PDT)

It does complicate the fuel piping somewhat.However, as 2RN needed some nose weight due to the relatively light A65, thatwas absorbed. Just more food for thought.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 26 Mar 2014 17:47:45 -0700 (PDT)
Pietenpol-List: Re: It's FINALLY a hangar...
Original Posted By: "AircamperN11MS"
N2RN got her tailwheel, horiz and vert stabs, elevators and rudder, WING, and anaileron reinstalled today. FINALLY...For the first time, a big structure is holding an airplane, so it's technicallya hangar I guess.Tomorrow is lots of adjusting wires, controls, cotter keying and safety wiringturnbuckles. Hopefully get the motor running. Early next week should be in annual and ready for flight. The runway finally seemshard enough to fly upon. Been a long haul on this one.[img]https://us-mg4.mail.yahoo.com/ya/downlo ... x&inline=1[/img]Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: It's FINALLY a hangar...

I'm not sure but you may encounter some icingproblems. I'm using a stromberg carb off an 85 Continental. It's aboutthe size to use since at 2800 RPM the engine H.P. will be about 83.5.My intake (with lots of help from Jack Watson, another builder) consistsof a couple of brass tubes (sink...P-tubes) avail. from the Home depot,an aluminum 'Y', a couple of 90 degree electrical thinwalled conduittubes and a couple of 90 degree elbows. A bracket holds the carb. andconnects to the oil pan (2 exixting pan screws on each side). The'P-tubes are soldered together so that the 1st curve of the 'p' comesout of the carb./bracket and the 2nd changes direction to aft and up.Then the 'Y' is put in place. The thin walled conduit is fitted to the'Y' with conduit connectors(screwed and epoxied in place), then the 90degree elbows are welded to the conduitand screwed down to the intakewhere the original carbs were. This also helps to keep the frontalprofile down. It's the shortest distance posible if an aircraft carb. isused and placed under the engine for safety. This way if you get gasoverflow it will drip down into the cowl and out the bottom instead of posibly causing a fire. BothJack and I have not used the original cooling fan. A presurized cowlshould work nicely if made properly. It's not like we have deserttemperatures here in Canada. The only time you would need to worry aboutengine overheating is when the ambient temp. is so high that theexisting cooling fins cannot disapate enough heat. That is the spreadbetween the engine temp. and pressurized ambient air. Are you also onthe Internet? I'm not flying yet, but I will be in the Spring.Regards, Domenico (VE3SNV)________________________________________________________________________________
