Fuel sender and speedometer

[imported_alex_G]

Hello all,

It seems that fuel sender does not work in my boat.
Does any one know part number?
What would be the replacement procedure? Is it straightforward?
Also speedometer doesn't work. I didn't check for a voltage to the gage but if it is 0 where should I look for sensor?

Boat Info
Bayliner 1985 Capri V8 5 liter

Thanks

Alex
