Gas tank sensor

So I pulled off my tank the other day to get to my carbs for cleaning. I am also going to re-paint the tank so I stupidly turned it upside down to drain my storage fuel and as I was tilting it I ended up getting something clanging around in there. I'm assuming the low fuel sensor came loose.

My Haynes book says to go to someone certified to work on gas tanks for repairs. I see a 'manifold' on the bottom that looks to hold the sensor. Would I be alright popping that open and digging around in there for this loose piece or should I bring it to somebody?

Thank you.

I had something clanking in my tank. It was a metal part of the sender unit guess its some kind of a cover for the sender wiper. Not sure how or why it came loose.

I was able to get it out but turning the tank upside down and then tilting it forward to get the piece up into the shallow part of the tank. With the tank up on its front edge I used one of those extendable magnet pick up tools and was able to get it out.

Pic is the piece I'm talking about.

Yes, don't bring this to a pro for nothing. Remove the back plate with the sensor attached to it, and pull it out. You will then be able to assess what's loose in there. It will also be much easier to get it out through the back plate hole.

IIRC the original stock sensor has a sheet metal plate attached with a couple of fasteners. The new stock parts do not have this plate. As Jack said pull the sensor out from the bottom of the tank. you should be able to fish the loose part out if it has come detached completely from the sensor. If I were you I would replace the sensor now as the tend to go bad with age. Plan on replacing the O ring seal while your in there. Also make sure you put the petcock vac line back on wrong nipple so you can come back and post about how the bike doesn't run.

LOL, already been there Xeris, but luckily read PVLR thread before making an *** of myself. Great advice.

Update: so here is what was clanging around in my gas tank. And yes, I labeled all of my hoses and read how ppl screw that up. I'll be repainting, changing CCT's, and removing the PAIR system so I'll prolly b back for more help. Thanks for the affirmation that I should look into the tank myself.

How does that nursery rhyme go? "The fork jumped over the spoon to shove the knife into the tank"? Or something like that.

Yea actually I should now that I think of it. I found one of the PO's crescent wrenches on the brake pad after I bought it. Had the rubber nipple cover holding it on.

I agree just remove it from the bottom. Its a pretty simple setup. I pulled mine and grafted in a CBR600rr float and sender to work with the dash from the same bike. Not a big deal just check for leaks.
