Left gas tank - modified with SW fuel tank sending unit $175

[boss-tiger]

Restored left gas tank, very good condition, inside looked like new before coating (hot tanked, muriatic acid cleaned, coated inside with Red-Kote, spray painted outside). Has been modified with Stewart Warner gas tank sending unit (included). I restored with original tanks because this modification was done very well previously and thinking someone with V6 or Alger swap may be using Stewart Warner gauges. Pulled out of Tiger I have now and didn't know it was even converted, car had multiple challenges so never paid much attention to gas gauge (probably only drove it 100 miles before pulling out the engine and non-op since) but from memory the gauge worked (have no clue re. accuracy). Looked up Ohm's on SW which are different than stock Sunbeam so assume you already know that. These sending units show up on ebay often if you ever need to replace the sending unit (new one now listed for $46 FYI). Hope of value/help to someone - FYI, also have a reconditioned right original tank I could sell also.

Will accept offers, trades, ? has anyone seen this done before. Would assume a perfect solution to convert to SW gauges

SW fuel sender additional info: seems this is called a universal 5 hole sending unit mount and there are lots of different sending units that fit this mount FYI. What is installed is a Stewart Warner sending unit that web search results indicate it opperates in 30 - 240 Ohm range. Our Sunbeams I believe use 22 - 228 ohm range BUT opperate backwards compaired to American standards back in those good old days. I.e. the US gauges show empty with max Ohm, vs our English sender/gauge function to show full at max ohm (hope I translated the web search results correctly). Would guess using non stock gauges such as Stewart Warner, Autometer, other you can work with this gas tank sending unit If anyone catches a mistake here (or thinks I am nuts) please post an update/correction. Also - tank is in VERY good condition and needs a new home (and I need the shelf space). FYI web search shows there are 5 hole sending units available that shold opperate correctly for our britsh gauge Ohms.

On the series 3 to 5, high ohms from a temp or fuel sender is the low end of gauge and low ohms from the sender is the high end of gauge.

Still have this 'unique' gas tank for sale- if any interest let me know - very good conditoin inside and these SW senders show up new on eBay often. FYI, I do have a good stock sending unit mount (patch panel cut off another tank that was rusted) if someone is in for a project.
