There are right angle tach cable drives (which also can be used to reverse the direction the cable turns) which could be used to allow the cable to run outside the tank.- The cable will have to be outside at some point, unless you make provisions to have a tube through your front seat passenger as well as the fuel tank, to allow passage of cables and wires.-Jack PhillipsNX899JPRaleigh, NC-

The problem is not where the low spot is, the problem is having the topsuface of the fuel in the tank lower than the carburetor in a steep climb.Even if it is slightly higher than the carburetor, with only an inch or twoof head there may not be sufficient fuel flow to maintain full power. Thepressure "head" is measured from the top surface of the fuel to thecarburetor inlet.Jack PhillipsNX899JP "Icarus Plummet"Raleigh, NC _____

A couple of sources I have not seen referenced on here . . . EBAY has tons of sellers with very good prices on 4130 of all sizes and thicknesses. Also=2C McMaster Carr sells the stuff on its website=2C which is the most user-friendly and useful site I have ever seen. They ship same day and are always very helpful. Both have more than competitive prices.Gene Ramborib stitching wing as we speak!! ________________________________________________________________________________Date: Wed, 17 Nov 2010 08:04:45 -0800 (PST)

Not necessary to actually run the engine for the flow tests. During these testsis a good opportunity to calibrate and mark your level indicator(s) also.AC 90-89A (Amateur-Built Aircraft and Ultralight Flight Testing) section 10 givesgood directions for fuel flow testing and FAR 23.955 (for certified aircraft)has good standards to shoot for:(b) Gravity systems. The fuel flow rate for gravity systems (main and reserve supply)must be 150 percent of the takeoff fuel consumption of the engine.This flow must--(1) Be shown with the airplane in the most adverse fuel feed condition (with respectto altitudes, attitudes, and other conditions) that is expected in operation;and(2) Be automatically uninterrupted with respect to any engine until all fuel scheduledfor use by the engine has been consumed.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Fuel Starvation

Gene brings up an excellent point... examine systems that are proven to work (asis the J-3) and emulate that setup. Well worth studying the geometry of theCub setup... the carb, gascolator, and fuel tank positions relative to one another....copy that setup and no calculations or engineering will be necessary.However, not even Mr. Taylor nor Mr. Piper can suspend the law of gravity, nordo they trump Archimedes' principles. The relative levels of the fuel in thetank and the float in the carb have to provide sufficient gravity head to flowfuel from one to the other or you'll need a pump. Stuff don't flow uphill onits own ;o)--------Oscar ZunigaSan Antonio, TXAir Camper NX41CCRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Jerry,Your gear looks great! I am playing with an idea to pad my axle with somestuff used to pad horse stalls (see attached). I have a lifetime supply andwould be happy to cut some strips for you, or anyone else who may beinterested.Gary Boothe-----Original Message-----

Jerry,Pads are going out in tomorrow's mail. I would be very interested to see howyou end up attaching them. My first thought is to just use a wood screw anda large washer. Maybe wrapping them with string would be moreaesthetic...now I'm starting to think about it...how about wrapping withleather, then wrapping with string and varnishing? That's how I'm doing allmy thimbles. The attached shows the first wrap. After that I decided to wrapthe entire sleeve and varnish all.Gary -----Original Message-----
