99 ultra 150 help
I have an early model 99 ultra 150, I have a question about spark plugs . It calls for R6918C-9 spark plugs, is there an alternative plug that doesn't cost $25, or a plug others use that work good. The previous owner has BR9ES installed, is that that an acceptable alternative?
Also I have a question about the fuel sending unit, it's suck at 3/4 of a tank, I pulled it out an did the resistance test per the manual an the resistance stays the same no matter where I put the float. I bought one off eBay for a 2001 an it did the same thing, but it did the same thing, and the guy says they worked when pulled from the ski, but I also read somewhere that 99 only works with 99. Is there any way to repair them or are they garbage. Any help or advice would be appreciated.

The expensive plugs were required on hull number 41803 and below, assuming your 'Ski has the original igniter. I use them because they came with all the '99s and they seem to resist fouling. When you sent in your warranty card for a new 'Ski, they sent you a spare set of plugs. I'm still running the original two sets of plugs, just clean them every season.
My fuel gauge failed, so I replaced it. They certainly don't give them away, now they're about $328. I took my old one apart and tried to straighten it with a heat gun (they warp with age, probably because of ethanol and all the other crap they put in gasoline these days). Mine worked until I heated it, then it wouldn't work. My nephew just bought a 2000 and we pulled the sending unit yesterday, it didn't work. For grins, we dug out my old sender and checked it, it DID work. I don't see any difference in the '99 and '00, though I've heard they are year-specific. The engine is out, so we can't test it with the gauge to see if it works or not.

'99 has a different part number from the '00-'01.

Didn't know that, maybe 00-01 are updated? But cant see why they wouldn't work. I used one from a 00 in an 02, worked perfectly fine.
