Fuel Sending Units - What to do when they don't work?

[RoadsterRich]

Okay, I am back with yet another of my gazillion questions.<P>I just pulled the fuel sending unit from the tank of the 1930 Chrysler 77. It has been repaired in the past, which it appears didn't hold up. There appears to have been an arm attached, I would presume with a float on it? It is no longer there, also the unit does not register resistance (well registers infinite resistance) no matter where the arm is set. Are there companies that rebuild or repair these, or is it better to find a source for a replacement?<P>Rich

Rich, can you post a picture of the unit? There are some replacements being made and one might work. That would be a lot easier than fixing what you have which is probably corroded inside too.<P>I have fixed and/or replaced several in GM cars. Replace is easier and I think better if you can find one that will work. ~ hvs

Howard,<P>For the help I get here I'd even post a picture of myself. Then again better I don't, I'd like to keep getting help <P>Below are a couple of pictures of the sending unit. The portion that goes inside the tank (from inside edge of the round portion to the tip of the other end) is 5 1/8", the top is 2 3/4" diameter, there are five holes which the mounting screws go through in to threaded collets in the tank itself.<BR><BR><BR><IMG SRC=http://www.1930Chrysler77.com/pics/fuelsend1.jpg><BR><BR><IMG SRC=http://www.1930Chrysler77.com/pics/fuelsend2.jpg><BR><P>As always, thanks!<P>Rich

Oh Boy ---- I've never seen one like that before. I can offer no further help, but the picture may bring in someone with more knowledge that I have. Sorry.<BR> ~ hvs

I sent one just like that to Wolfe in Cleveland(actually suburb, but brain fade has set in) along with the dash gauge and got it back with new arm,float and calibrated, only took a couple of weeks and looks like original installed. He advertises in Hemmings I believe. Think its Willoughby,OH, John Wolf. In services under fuel gauges

To add to the description:<P>The center 'shaft' has a gear at the lower end. This gear is turned by a second gear, to which the float(?) arm was attached. As the float(?) moved up and down, the arm would move up and down, turning the shaft. I presume the shaft attaches to some sort of variable resistor in the top unit.<P>Thanks,<P>Rich

cmj, this is the only John Wolf I found in Willoughby, OH. Sound right?<P>John Wolf<BR>4550 Wood St<BR>Willoughby, OH 44094-5867<BR>(440)951-3728

To follow up on this, I will most likely be sending my unit to John Wolf, Co. However, I am contemplating purchasing a modern universal unit from J. C. Whitney. It is $14.95 for the one that works with Chryslers. I have heard from a couple of folks that these work well. The URL for them is:<P><A HREF="http://www.jcwhitney.com/productnoitem.jhtml?CATID=65164" TARGET=_blank>http://www.jcwhitney.com/productnoitem.jhtml?CATID=65164</A><P>Rich

Rich, you might want to double check the resistance range you need....<P>When my sending unit failed in the 1970s I used a Stewart-Warner replacement. Before doing so, I got some resisters and used them to determine what resistance I needed to show full and empty on the gauge. My memory is not what it used to be, but the range listed for the Stewart Warner sending uint on the JC Whitney page you linked to seems closer to what my 1933 car needed.

Will double check that, thanks for the heads up!<P>Rich
