The front and rear springs are now on.  Emergency brake release being cleaned up.

Does anyone have an extra fuel tank sending unit/float 6volt for sale?  I will start looking for a NOS one or a good used one if possible... 

Please chime in with any thoughts on who may have one

thanks!

There is a man in CA named Bob Gunthorp who has some old parts for sale. I bought from him before.
His Email is badwrench7@cox.net
He usually posts on the ponton site.

Are you missing it all together, or is it just in need of repair?
When I was having my gauges restored by Palo Alto Speedometer, the question came up regarding calibration of the fuel gauge.
In my case I was able to repair my sending unit and do my own calibration but he did mention that they have some options available.  I believe one of those involved using a newer style sending unit, but you'd have to get details from them if you want to go that route.  Somewhere in the past, my float had been altered.  I believe the original floats were cork, but mine is now plastic.  I'm not too concerned about items like that which are not visible at all and increase reliability.

Charles, just checked with Bob but he has no 52 220 parts.  Scott, I think I still have it but it was pretty rusty as I remember.  I had the gas tank cleaned out a couple of times and it had sat in the car for years before the float was removed and pretty much was dead.  I think there might be some chasis in Germany on ebay and I seem to remember the tank still intact so perhaps they may part...  I will have to send an email.  I have a few emails out to some of the german parts places and ebayers but so far nothing. 

thanks for the help!

It's just a simple, wire wound rheostat.  I think it reads about 1-10 ohm when at the empty range and around 135-140 at full.  I tweaked mine so that it read "empty" at the point the shorter pickup tube stopped.  That way, I was more comfortable that I had "reserve" if I needed to switch the flow lever. I thought I had taken some pictures of the inside of mine, but all I found were shots of it when I was adjusting the calibration.

Scott, thanks and great photos!  I am looking for my float and hopefully will find it.  I took some photos of part of my dash where the radio normally goes.  I have a sun tach there.  I would assume this is not factory?  Any thoughts?

[John Ellis]

Not factory .... no such option,  but that is really an old Sun tachometer.  It is called the football tach due to the red emblem on the face.  It was made in 1950's to early 1960's era and is worth somewhere between $200>300.  Sun was "the" tach for race cars, muscle cars and hot rodders.  Retro and popular now for rat rods.

Do you have the transmitter also?  It would be specific to the voltage and number of cylinders.

[yan2947]

Ellis, I do have it in a box with rest of my parts.    It had always been installed but I never had it working.  Once the motor is rebuilt I will try and get it working or see if the hole in the wood dash will fit a radio.

Hi,

If you are interested I have this dash part for sale.

[John Ellis]

Yan2947 .... your wood trim was a blank before drilled for the Sun tachometer.  You will probably want another blank or fit for a radio like Lars has offered.  The original radios can be quite expensive .... up to $1,000 US.

Lars ... is your blank for a Becker Monaco?

[yan2947]

Thanks for the photos and offer.  Still quite away from interior install but will keep all in mind.

Thank you

The fuel tank level sender is MB part no. 1815420004.  It is available from mercedes new and the best price I could find is from the following vendor:

I have no experience with the Parts.com store so can't endorse their reputation.  Here is a MB on-line dealer with the same part for a few dollars more.

John,  what is the difference in the parts manual from the part number you gave just under part 7 of table 34 in group 47 and part 8  1875420104?

[Scott Montoney]

If I read it correctly, one is for the early cars that had a 48 liter tank, the other is for cars starting with 01017/52 that have a 65 liter tank.

[yan2947]

Scott, so my vin is 1870110858352  which means serial number 8583/52?  So I would be the second part, 1875420104?  Would it be correct that either would work if I can get my hands on one and it can be changed to work in some way?  Both would be 6 volt?  I have an email out to classic parts to see if they have either.  I will try the other people that John suggested as well.

thanks!

[Scott Montoney]

I hope others can confirm or correct, but that is my understanding.
My guess is that the main difference in the two is probably the length of the float arm. But that is pure speculation.

[yan2947]

I think you are right.  Mercedes is out of both.  None on eBay but I will keep looking.  There are a few 6 volt ones on eBay that I am sure will work with some adjustments.  I had the tank dipped a couple of times in the 80's and it looks like it could be done again.  I would rather split it open and sand blast it and powder coat in and out, then weld it back.  Any thoughts on that?

[Scott Montoney]

Yes.  My tank was done by "Gas Tank Renu" in 1999.  They were in Detroit, MI.  I believe they split the tank open and coat it inside.
I'm sure there are others as well.
