Fuso fuel sender
- Thread starter boostin
- Start date
possibly not . i use a short length of copper pipe with mu two tanks . just dip them .
saves alot of bother .
i did at one time play around with the sender . lengthen it etc and adapt it . that was on one tank i fitted ,but on the tanks i have now i give in . in fact one tank i use is a mercedes tank it doesnt have a sender at all.
after about 800kms its time to fill the first tank.
about 1200kms on the second tank . but by then i have found a fill up.

So I just used the factory fuso sender in the tanks you installed?

I replaced the stock 33 gallon tank with a 50 gal plastic tank from Northern Tool and Equipment I used the old sender. The tank is plastic, easy to drill new holes in it... I did have to do some bending on the float arm to get something close to an accurate reading but the sender was calibrated for a cylindrical tank and the new one is rectangular, so sometimes the reading seems a bit funky. After mounting it I poured the 9 Gal of diesel back into the new tank and nothing showing on the gauge. I guess I didn't bend things enough. If you are going to have an error on your gauge, I would rather it show empty and you still have several gallons of fuel in there. Fairly common on fuel injected vehicles now to read empty while there is still several gallons of fuel in the tank. Of course, I had to run a ground wire so the sender would work. I've thought about mounting the old tank with the proper valves and return lines somewhere on the vehicle, over 80 gallons of fuel on board would be nice until you had to hit the gas station. You are going to be burning that fuel anyway, so it just means you can get to a place with a better price, hopefully. I complain about fueling, A friend drives over the road in his semi. Two 150 gallon tanks so that's got to put a hurt on the old wallet. Sorry about the rambling,, lack of sleep does that.

If you want to use the stock fuel gauge you will need to use the stock sender... I have the stock sender but since the tank is deeper than the stock one it takes a while to come off 'Full' and start dropping.
Mostly I just pay attention to how many miles I've driven.

Not 100% true, but definitely easier if you can do this.
The standard round 110L OEM tank is 400mm deep. If you have the same depth on a replacement tank that makes things much easier.
However... when I had custom stainless steel tanks made the depth was 500mm. Initially, I replaced the sender wire that holds the float with a length of stainless steel TIG welding rod. That worked okay, but I was never really happy with that solution. The final solution, which I am happy with, was to get a custom fuel sender manufactured that had the correct flange and ohm range.
As mentioned previously, the OEM sender and fuel gauge are calibrated for a round tank. If you want the gauge to read correctly at full, half and empty then you need to use the same ohm settings at those points. For a Fuso, those are zero ohms at full, 50 ohms at half and 150 ohms at empty. As should be obvious, this is not linear, but there is little you can do about that if you want to use the OEM fuel gauge in the dash.
The image below shows both of my senders.
The problem is I have a rear in the frame mounted to the side but it leaks at the seam so I wanted to at least install a side mount fuso tank.
None in Canada so this will get expensive..found a w5500 tank which looks the same as the fuso but with a isuzu sender.
Guess my in frame tank sender is different then round tank.
Not trying to be cheap but I am on a budget.

Given that many of the specifications are different between the US and Ozzie trucks, that does not surprise me. Kinda stupid, but understandable.
Why would they be different?

My only answer to that question would be... because they can be different.
The image below is out of my FG84 manual.

interestingly, I also found this. The 4/135 may be for in tank testing and the 0/150 could be for out of tank testing?
