Attached is a visual of what the problem is. Essentially any fuel trapped in the vent side of your sight system above the fuel tank fuel level adversely affects the fuel level in the clear sight tube. Not to insult intelligence of anyone, but the only way to keep the sight tube vent side clear is to run it uphill all the way to the vent. I personally don't like the overhead vent because the low pressure area over the top of the aircraft creates changes in the sight tube level also. To remove some of that problem, I prefer folks to put a tee in the fill neck to allow the tank and the sight tube to be the same air pressure. That said, running the sight tube vent side so that fuel can never be trapped in the line on a mono or trigear is very difficult. At times for a tail dragger, it is impossible. I have a sight gauge in my trigear that works flawlessly. But it runs above the tank, downhill from the top of the fill tube. But it still can get fuel in my vent side. I know mono owners that have very accurate sight tubes but took great care not to trap fuel in their upper line. Following Chapter 30 of the build manual, it shows a method to run the foot mounted sight tube and it works well normally at cruise speed. Most government regulations on aircraft require some means to visually determine the amount of fuel in the fuel tanks by the pilot during preflight because electronic gauges and senders are prone to their own inaccuracies. I have a sight gauge, a fuel quantity gauge, a fuel totalizer, and a wrist watch and knowledge of my engine's fuel usage per hour. I also carry a small piece of tubing which inserts into the inside of the fuel neck on to the tee to blow out any trapped fuel that some line boy fueling my aircraft injected into my sight gauge line. Talk about the department of redundant redundancy. In the analysis from years of tinkering on quite a few aircraft: The Europa electric fuel gauge works pretty well for a resistance unit. The capacitance types work OK unless you change fuel from 100LL to auto fuel as the capacitance is different leading to inaccuracies. Fuel flow senders work generally well. On my 914 I have a JPI. If I set the fuel on the totalizer accurately, it is dead on accurate. The Grand Rapids dual flow are OK but require a bit of setup tinkering then are quite good. The 912 and 912S do not use a return flow meter and are OK but no system on these engines works perfect, but it is close. Dynon newer systems like the Skyview use dual fuel senders and seem OK, but all the older units can only use one sender and are fairly accurate on the 912 series engines. Sight gauges are a necessity to assure you that you have sufficient fuel to complete a mission unless you always top off before any flight and land well before a fuel low situation. I just never find myself in those circumstances...

Trust you have had a good xmas and are looking forwards to 2013. Mr father in law and I have been trying to figure out what fried my Narco com earth terminals. Think we found the cause but have some questions for any avionics knowledgeables out there. The most likely current path was battery +ve to external charging point connection (no fuse in that wire) and across to the aerial earth (quite possible that a metal aerial interconnector could have touched the charging point +ve terminal as they are in close proximity). The aerial earth is in connection with the radio case and radio/transponder tray. The radio/transponder tray is not earthed so the current returned to the battery via the radio earth terminal - which fried. I will be looking closely at the siting of wires and insulation to try and ensure no contacts can occur - but should be ensuring that such contact will not do any damage. You won't be surprised to see that the questions are about earths and fuses; 1. Should the metal radio/transponder tray be connected to earth? 2. I cannot find a fuse protecting the main bus bar. The master switch works through a solenoid which connects battery direct to main bus bar. Is it advisable to have a panel mounted 25amp circuit breaker between battery and main bus bar? If it tripped I could then turn off selected circuits and reset this 25amp circuit breaker and attempt to diagnose the fault. 3. What fuse amperage would suit the requirements of an external battery charging point? Is it best connected directly to the battery +ve terminal? Hope the weather where you are is better than it is where I am William Bliss ________________________________ Message 4 _____________________________________ Time: 12:41:26 PM PST US Subject: Europa-List: Filling/Painting Classic wings & Tail. SUPERFIL? SP106? From: "G-ODTW" I thought it a good idea to get my tailplanes balanced before I put my top on. They needed filling (I used Ampreg21/Expancel as per Europa manual) & then will need painting. But I am now finding it a heck of a job to sand the filler. After 2 days of it, I have had enough. The sandpaper constantly clogs, and it is bl**** hard work - And my Classic wings are much bigger than the tail! Some people seem instead to use Superfil. But I am also told that SP106 is the resin many people use for the surface filling job, which sands without problems, presumably with the supplied Expancel. Many folk have trodden this path before me, using many methods. 20 years on, is there now a "best practice" for filling / sanding / painting? All advice greatfully received. Thanks.
