I've got wings on with 10 gal of fuel in each tank, and I have the 15 gal tanks. I put 5 gal in each tank and the gauge needles were both showing empty, but they did move. Put 5 more in each tank and they read just over 1/4 full. They should be reading 2/3 full. I checked with Zenith that they had sent me matching senders & gauges, & they confirmed both are the 70-10 ohm type. I have not checked the this yet with a multimeter. I did some internet searching and found the VDO gauge I have has an adjustment screw located on the side of the barrel. Have those of you who have been down this road before had to adjust the gauges using this screw to calibrate what's actually in the tank with what the gauge shows?

I made the mistake of buying them and they are just plain junk... ok for a VW car, but not for an aircraft! My VDO junk is for sale now cheap! I have replaced them with ISS gauges and Senders made by Stewart Warner! I found them at Van's which are standard in all of Van's kits. They also have them at Aircraft Spruce and sold under the ISS brand. I bought the gauges at ACS... as Van's(branded) gauges are calibrated in gallons! Van's Senders are the same as ACS... left and right. At ACS the Senders are $33 and $39 and I don't know why. Anyway I bought the Senders from Vans for $27 each L and R! Van's supplies full instructions on how to bend the float arm to fit your tank... it's very easy, I don't know about ACS! http://www.aircraftspruce.ca/catalog/inpages/issgauges13.php http://www.aircraftspruce.ca/catalog/inpages/issgauges11.php ISS FUEL SENDER RH 6-12 TANK - $39.75 ISS FUEL SENDER LH 6-12 TANK - $33.00 http://www.vansaircraft.com/cgi-bin/catalog.cgi?ident=1339704419-84-258&browse=ei&product=vans- fuellev - Part Numbers = IE F-385B IE F-385C Price = $27.00 I compared them to the VDO junk and it is like night and day.

I took Ron's advice and purchased the all the parts he recommended. Best recommendations I ever received. Robert In case your worried about the holes in the tank sides ( if you made them ) don't, since they can be used with the new senders, however you will need to tweak the sender wire to get a correct reading. fly safe ----- Original Message ----- From: "cdnch701builder" Sent: Thursday, June 14, 2012 4:34 PM Subject: Re: Zenith701801-List: VDO fuel gauge question > > > Hey Jimmy > > Get rid of that VDO junk!

They also connect to fuel flow senders. http://www.mglavionics.com With regards to capacitive probes be aware that they give different readings when you switch between leaded and unleaded - basically anything that changes the dielectric constant of the fuel. -- Craig ________________________________ Message 6 _____________________________________ Time: 06:32:47 PM PST US From: cdnch701builder Subject: Re: Zenith701801-List: VDO fuel gauge question --- MIME Errors - No Plain-Text Section Found --- A message with no text/plain MIME section was received.
