2000 Bayliner 1850LX. I need a fuel level sender so I don't get stranded in the middle of the lake again. Where do I find part numbers for stuff in & on the boat itself?
Engine stuff--no problem. Outdrive--no problem.
I can't find squat on hull parts.
Clue me in where to look.

Fuel senders are pretty universal. It should be easy to find a replacement. Tank height is usually the only variable, and there are ones that can be cut to the correct size.

Other hull parts are not universal, so you need to get measurements etc., and match something up.

First make sure that it is not a loose wire. Then test the gauge. If both are good, pull the gauge. Kiekhafer, the owner of Bayliner, often uses Faria for their gauges and do not make their own. The fuel sender is also an off the shelve piece of equipment that can be replaced by another off the shelve piece.

Well if senders are kinda universal then maybe the smudged marking on it reads UMW 6½
And there are 6.5 senders. Should work?

This forum won't let me attach a photo.

This is probably what you are looking for,but you should pull the original one and compare.

Hmmm.
Most the ones I looked at... Sierra, Seasense, etc on Amazon, eBay or most parts websites were 240-33ohms. I ordered one from Amazon that came up when I searched UFW-6.5.
I found this same sensor (with clearer markings) used on similar sized & powered boats.

For $30 I'll find out at the end of the week.

Right now I'm a little more baffled why I ran out of gas at all. All the specs I've seen for my boat say it has a 30 gallon tank. After I got towed back to dock I put all the gas I had into the tank--2 5-gal cans + maybe 12 gallons in my gas caddy. Total 22gals at most.
After cranking a few seconds it started. I went for a quick spin.
When I pulled the sender I found the gas level tickling the top of tank.

What else could I look at to explain running out of gas with possibly 8 gallons still in there? What kind of fuel pickup is (was) used on a basic carbureted engine in 2000? Should/could I suction ALL the gas out and carefully measure how much it takes to reach the top of the tank?

Could be the pick-up tube has a hole in it above the pickup itself . Which is just a 2" -+ round flattened funnel attached the the tube with a wire mesh over it . Fuel pump from motor draws fuel out .Or you're off in the capacity, which may be listed ,imprinted , close to the sending unit sealing plate . Rule of thumb is 10% of capacity listed is not going to be picked up because of it height above the bottom of the tank and where it's located in relationship to the running angle of your boat . So that could be 3 - 4 gallons . Carrying a 3 + gallon gas can't hurt to be tucked away ,if you have the space . At least until you get it figured out .

Boat manufacturers publish very little information for serviceability (as you know).

My approach on boat specific parts has always been to access/remove the part and grab the mfg. name and any numbers off of it as much as possible, then go Googling.

The manual link is to a small supplement to the OM. The actual manual isn't available *anywhere*.

The sender I received today looks identical to the stainless one rolmops linked to in an earlier reply.
I swapped it in and tested the float/gauge operation before mounting it in the tank. Gauge now responds smooth & linear to float movement.

Tank depth is 7.5" from gasket to bottom of tank. From what I've read it's standard to leave that extra inch at the bottom--tho I never found a reason why.

My recollection on fuel tank (and other tank) senders is that there are 2 ohms scales . . . USA and European, so you want to make sure you are matching what the gauge is expecting to see for resistance.

Google/AI states:
"For the standard American version sender (240-30 ohms), you will have between 232 to 252 ohms @ empty, and 28 to 36 ohms @ full. For the standard European version sender (0-180 ohms), you will have between 0 to 2 ohms @ empty, and 171 to 192 ohms @ full".

You would not want the sender touching the bottom of the tank as it will create a 'wear point' due to vibrations, so the 1" short is a preventative thing . . . plus when the fuel gauge reads "E', that would stand for 'enough' (to get home).:LOL:
