Has anyone tried putting a fuel gage or low level indicator on the older B models? I have a 1979 B7100 I would like to either add a fuel gage or low level light. The tank is so discolored, you can't see the fuel level without lifting the hood and looking in the tank. I have replaced a pricey sender with a marine generic fuel sender on one of my Wheel Horses. It cost less than $20 for the sender, but was fairly easy since the standard VDO flange was already in the top of the tank. So, if I go this direction, I will have to cut a hole in the top of the Kubota tank for the sender flange and mount a compatable gage somewhere on the dash. Does anyone have a better idea?

u could find the fuel gauge thats built in the tank cap.
You mean like the lawn tractor type. I would still have to raise the hood. I'd like to have indication without lifting the hood or fuel cap.

u must be a young fellow.LOL yes lawn tractors, outboard tanks, aircraft,
model t fords, ect had them. that was before the elevtronic age. the L series
of bota,s have a hole in the hood so u can fuel up without opening the
hood. make a hole in your hood. as a side note, if y have rust in your tank,
check the cost of a new tank. ouch u say, even worse, they tell u no longer availible. my L1500 tank same as L175 is $700 and no longer availible. see my first post as to what i did. POR brand makes a motorcycle tank repair
kit that will stop the rust before it,s to late. i used it after i welded a new
bottom on my tank to stop rust on the rest of the tank. the japs aloy
all there parts with gold, and the price reflexs it. :D:D:D

LRP, if being born in 1947 is young, then I am guilty. LOL No, the B7100 has a plastic tank. I have the level indicating caps on my older Wheel Horses and I don't want to raise the Kubta hood or cut a hole in it to see the fuel level. I would really like to clean my old plastic tank so I could see the level, but I don't think it will clean. I will probably adapt a fuel level indicator of some type.

if the tank used to be clear enough to see the fuel level when new,
u should be able to use 600 up to 1000 grit sand paper on the inside and outside. the will no give u optical clarity, but u should be able to see the fuel
level. another option is to drill 2 holes on the vissible side of the tank and install 2 90 deg bulkhead fittings with a hose. or check the hydralic shops,
they have oil level indicators that bolt on the side of the tanks. how to install
one of these my be a chalange.:)

Simple fix. Just fill it up every time you use it. It's hard to sit on a B model long enough in one day to run a whole tank out.

Thanks for the inputs. I think I will try scouring/sanding to see if I can get any view of the level. I'll let you know how it goes.

to optical clear.

I fill my B7100 after each use. I have never had to refill during a day of operation. Even under load brushhogging, after 3 hours I don't think it took a gallon. My tank is so dark I can't tell the level even with a light shining down the fill hole. I am just going to keep filling it after each use. I have seen one painted blue with the frame paint and thought it looked nice, planning to do that to mine when I paint it this spring.
