    Posted: 16 Jul 2017 at 11:56am
Dang, took the D15 II out on its maiden voyage the other day.  All went well except the seep at the bottom of the fuel gauge.  it bubbled the paint overnight.

So i got a new/another gasket on order and a new vented cap.

i am going to yank the tank today and will be checking for straightness of the gauge and mount on the tank and also for any cracks in the mount on the tank.

So if i get all the above done, what would you recommend when reinstalling.  Permatex on both sides of the gasket or what.

thanx

I'm not big on sealant, but of course sometimes you have to use it. On the paper type gaskets I usually work some grease into them to soften them and helps them compress so they fill small low spots and if you have to take them off in a few days for whatever reason they most likely are reusable. Hope it helps.

The gas gauge uses a larger o-ring for a gasket.  Snug your screws up first.  If not then find a new o-ring at a parts store.

MB, are you sure about the O ring?  My parts book shows 0228119 as a fuel tank gauge gasket.  That is what I have on order.

I think the gauge rubber gasket has a square cross section, that's how mine are.
I think an "O" ring might work though.

No Permatex required.  I got my gaskets from AGCO and never had a problem.  Make sure the threads in the tank are clean and the screws go in all the way.

I cleaned up the threads with a tap.

I ordered the gasket from Sandy Lake.

We will see what it looks like when it gets here.

Any decent size welding supply shop should have petroleum rated material you can make a gasket out of, for less than 10.00. Never had one leek where I have used it.

DSeries4 and Scott

I think I found the problem.  Long time ago i musta put a gasket in there that was from aftermarket.  It was disintegrating.  So I got the thicker neoprene type from AGCO.

What is your technique on tightening up the screws as far as how tight they should be?

thanx

repeat SEVERAL times( like 1/2 turn each)
until LITTLE 's'nug

NOT big 'S'nug
NOT little 't'ight
and
NOT BIG 'T'ight !

You want even pressure all around.

Also gaskets are not all the same, you need one rated for gasoline ! Some aren't and gas WILL 'weep' out so you think, hmm..not tight enough, SNUG them down and oospy, things break....sigh ... yeah I found out the hard way......

I need to change the gasket on mine, Anyone have any tips for removing the bolts holding the gauge on without breaking them off?

PATIENCE !!
I used a big slot bit on a 1/4" socket set. You NEED to have the bit FIRMLY in the slot and tight. Try a quick twist to see if it will release, if so THEN 1/2 turn out, 1/4 turn in.
You may need to move the hard plastic 'trim' piece, the key is to have the bit firm and straight in the slot, magling the slot isn't allowed...
Just be sure to NOT allow it to 'bind' up('dirt' in threads) otherwise you're in BIG trouble. One of mine wasn't in good shape and I had to use baby vice grips, 1/16 of a turn at a time..sigh..that took a long time to undo....
I think they are 1/4-28 ( fine thread) bolts. If you mangle one and NOT a purist, replace all with socket head cap screws.

I double checked are D series gauges.  One does have a o-ring, the rest are a flat rubber gasket (much like a mason jar ring).  Any rate it is rubber rather that paper material.

Mine are all mangled from someone else trying to fix it, looks like it's the vice-grip method.

Travis, if you have it take a look at using a die grinder with a small cut off wheel and kjinda straightening up those screw slots.

Mine have already been changed over to Allen head screws.
