Hey Everyone! I know this topic has been beaten to decease because I merely spent an 60 minutes going through various posts. Here is my state of affairs I hope someone can help me with. I have a 1973 Campmobile with vibrator setup. -New tank, Sender and vibrator has been installed during resto. I think my next step is to ground the gauge to run into if it goes to full, if it does then I probably have a sender issue but if it doesn't and so it's probably a judge result. Am I correct in saying this or would a poor ground cause my sorrows? I'grand kinda scratching my head on this 1. Thank you for whatever and all help!

Begin unhelpful mail� Mine does this as well. For me, information technology ways my needle shows R when I accept a niggling over a quarter tank left. When I get to R, I become gas when convenient. I prefer information technology to my Jetta, which shows full when full, and sputters nether a quarter tank�� _________________ www.airschooled.com

what type of sender are you using? If information technology is the lever bladder style the float arm has to be bent until information technology reads correct. I ran long wires to the bus when the tank was empty (no fuel or fuel odors were in information technology otherwise put some dry ice in the tank for awhile and then it fills upwards with CO2 so a spark doesn't set it off). Then I used a wooden yardstick (no spark) to lift and lower the float arm. Picket the gaiuge until it reads correctly or close to information technology. If it is the hollow tube with the float inside the tube manner I don't have an answer.

SGKent actually? Y'all accept to bend the sender arm to suit the approximate? That seems bizzare to me and why wouldn't the instructions tell you lot to do this when you install the new sender. Everything is neatly tucked away behind the firewall and the engine is back in and has been running for months. I'd detest to have to pull everything to do an adjustment or practice the forbidden and cut an access pigsty.. There has to exist another way. I work at a dealer and I can borrow our Resistor Decade Box http://vw.snapon.com/specialtoolsdetail.aspx?itemid=1270013 to apply varying resistance to the gauge to see if it'south the issue. I Actually don't want to pull the sender once more that'southward why I replaced it in the first identify... _________________ 1973 Campmobile rustoration in progress.. 1700 Type 4 engine Manual Transmission Pertronix Mechanical advance benefactor Pertronix Flame Thrower scroll Weber Progressive Come visit our Facebook page! http://www.facebook.com/pages/Freedom-the-Campmobile/158775277473211 Click to view image

I hope that article helps you out Wasted, every bit for bending the sender, I think I'll go on diagnosing the upshot. _________________ 1973 Campmobile rustoration in progress.. 1700 Type 4 engine Manual Transmission Pertronix Mechanical advance benefactor Pertronix Flame Thrower curl Weber Progressive Come visit our Facebook page! http://www.facebook.com/pages/Freedom-the-Campmobile/158775277473211 Click to view image

Wasted youth/adulthood wrote: Hmmm....bending the sender arm....if the cuff once worked accurately with the aforementioned sender, merely now reads off past a big percentage, I would recollect the event would not be resolved crorrectly by angle the arm. It must be an electrical issue of some kind. If your sender is the arm kind, there is a possibility that the resistive wire that the arm scrapes along has been worn out at the top. At that place's a thread around here chosen "Fuel sender 3$ refresh" or something, and the pictures in there will clear upward any disruptive details I've muddled in. Can't post much more from my telephone.. _________________ www.airschooled.com

SGKent is correct, y'all need to bend the arm on the new units, fifty-fifty on the new VDO ones. 2010 thread hither: http://world wide web.thesamba.com/vw/forum/viewtopic.php?p=4576662 When I replaced my old VDO sender with a new VDO i, I but lined the round cap of the sender that slots in the tank up with a shelf in the garage, remember of the superlative of the shelf as being the top of your fuel tank, when you heighten the float on the newly fabricated modern units, information technology levers to above the peak of where the fuel tank will exist. (Switch your multimeter to Ohms, it will testify that there is yet 1/four of a tank total of travel left on the windings when the float is hitting the top of the tank). What y'all need to do is bend the arm then that when the bladder reaches the end of how far the arm can travel, it is level with the underside top of the tank (i.e. only beneath the line of the top of the shelf / sender cap - hope that makes sense?). Why do yous have to do this to these new units? I call back poor quality control, they are't fabricated in Frg anymore, and they don't make them like they used to! Making small-scale adjustments to electrical instrumentation is quite a normal occurence, even with the best stuff. Also, you need to compensate every bit the onetime floats had a flat top, the new floats cylindrical all the way effectually. Here is an paradigm of an old VDO sender, and a repro Flotamex sender posted by Pearl the party bus (which he sent back as it would not lock into the superlative of the tank): http://world wide web.thesamba.com/vw/forum/album_page.php?pic_id=250881 Here is a new VDO unit that you demand to bend the arm on, otherwise 3/iv tank is the max yous will e'er read on the gauge: _________________ 1965 Type i Deluxe (1200cc) 1976 Type two T2b Microbus L (1800cc Blazon 4) Previously... 1972 T2 Camper (Devon), 1988 Golf, 1972 Type i, 1984 Polo, 1972 T2 Camper (Danbury)

Like chimneyfish and sgk said, There is no other way to adjust the bladder without bending the arm if both 'cease tabs' cannot do the "empty to full range" Even the new cars with in the tank pumps and tank floats are inaccurate when replacing with Bosch,Pierburg and Siemens products. Just rule out the dash gauge and vibrator first earlier putting the tank unit back in. _________________ V.Westward.owner since 1967

Bend the stops until the gauge reads full (it may be and then poorly made information technology tin can't be made to do this) and then go back and bend the arm so that the float pretty much is at the same superlative as the plate on the send when the sender is sitting upside down on a level surface. Measure the depth of the tank and cheque to run into that the float drib is about the aforementioned as the depth. Putting a crook in the arm to shorten information technology volition sometimes give better readings over the whole range. Adjacent fourth dimension I accept to supercede a bad sender, I think I will just buy some wire and rewind the erstwhile i. Information technology'due south the $hits to pay out the a$$ for 2nd class parts. If anyone knows a source of accurate senders information technology would exist nice if they would post.

From ratwell.com, based on the tardily coach which has the bayonet twist style to fit into the hole. Before you lot install it, measure it with your ohm meter as follows: y'all should top out at 13Ω when the Tiptop of the float reaches the imaginary horizontal line fatigued across by the bottom of the sender plumbing fixtures. _________________ "Consistent maintenance with quality products is the cheapest warranty you'll ever need." 1977 CE1 Transporter Deluxe, Subaru EJ22, Skills Cooling, Steedle HD 091 westward/ GuardT .81 4th Click to view prototype

They show what I long suspected from the parts diagrams. The original style floats saturday higher when full. The late float can't come up up as high considering the float rides on the top of the arm instead of the bottom. I've had 2 new VDO units and they all were the late style - all read 3/4+/- when full and had almost 1/4 left in the tank at empty. The skillful news is that I have a spare from the episode.

Touch forest, the needle has non bounced, it's been steady and reliable so far, and adjusting the arm before installation as described above has enabled accurateness. _________________ 1965 Type 1 Palatial (1200cc) 1976 Type 2 T2b Microbus L (1800cc Type 4) Previously... 1972 T2 Camper (Devon), 1988 Golf, 1972 Blazon 1, 1984 Polo, 1972 T2 Camper (Danbury)
