I got the factory drawings a while back for the fuel tank on my 1987 SR357. I scanned it and will email file if it will help anyone--it's too large to post.

That is a great resource.

I think my fuel sender in my tank is going bad. I looked at the sender (VDO) but couldn't determine the part number.

FYI--If you can replace the VDO gauge then you replace sende that would be a good thing. VDO gauges and senders are different that everyone else in that world and there is no way to interface except by changing sender and gauge.

I found that out after genset was installed over sender and needed to replace after it took a dump.


I'll email you diagram and part number when I get home tonite if it will help---

Great. My gauge is "pessimistic." I went to fill up the other day, gauge showed near the red. When I got to 3/4 tank on the gauge the tank was full, couldn't get a drop more in there.
