332 fuel tank grommet replacement

I tackled the 332's fuel tank today. Since I have owned it I have not been into the tank for any reason. I decided that I would go ahead and replace the 2 grommets (fuel line & return/fuel sensor line). Getting the grommets out is not too much of a problem but you do need to make sure that you do not tear up the fuel level sensor when you take it out. As others have found, the pickup line on mine was rotten and brittle. It broke off as I was removing it and after I got the last piece out the hose itself just fell apart in my hands.

Assembled pickup. Note that you do not need or want a real long piece of fuel line. If you look on the bottom of the tank the reason becomes obvious; there is a square recess that is the lowest part of the tank, I believe that the intent of the design is that the pickup should rest inside of that recess.

Assembled fuel level sensor. The orange grommet is the new one. Getting the old grommet off is straight forward - it will either fall apart or you can cut it off. I ended up cutting mine off.

Getting the new grommet on the sensor is trickier. The hard part is getting the new, tight grommet past the sensor without tearing up the sensor in the process. I ended up using a 7/16 deep 1/4 drive socket and a vise. I put the socket into the vise with the bolt end facing up and then forced the new grommet face up over the end of the socket. I used some vaseline to make this a little easier. Once I did this I was able to put the end of the sensor into the socket and then slide the grommet over the sensor without tearing up the sensor. I don't know if this is the approved way but it worked for me :)

So far, so good - I went back out and mowed a walking path for my wife around one of the pastures.

Thanks for the idea on the sensor grommet. I ruined a new sensor trying to get it over the bulb on the bottom. I called GreenParts and asked them if I bought a new sensor from them would they put the grommet on for me and they said NO.
Thanks Frank. Your tip will help a lot of folks with that delicate job.
I had to replace both grommets in my 332 fuel tank today and although I did not have a socket that was deep enough for the hole probe to fit into I did use an aluminum tube that was about the same size. I cut and squeezed the end of the tube so that it became a point and then greased the heck out of both the grommet and the tube and was able to push the grommet onto it. The squeezed in was at the other end and did not come into play. One final thing to remember is to put the grommet onto the tube in the correct direction or you will have to pull it off and do it over again. I also greased the hole in the tank and the grommet to help seal it and work it into the hole.!
