I'm trying to get this Bobcat 250 running, I got it for a good price its sat on a service truck most its life. Only 100 engine hours on it.

Anyways the issue I've got now is the gromet that seals around the fuel suction line cracked and started leaking gas. I got a new one that fits both the hole and the line, but the tank wall is almost 3/16" thick plastic and the gromet wouldn't seat properly and it leaked. I also notice that its now turned into like a hard plastic instead of a flexible rubber, is it possible the rubber gromet needs to be rated for gas or oil? Or isn't that the reason it turned so hard.

Miller doesn't have a part number for it, I can only order the whole fuel line, I don't know if I want to order a $100 part and hope that a $2 gromet comes with it...

Any help much appreciated!ImageImage

Try this outfit ? http://www.servicerubber.com/rubber-sil ... ommets.php

If you have no luck with a grommet, maybe use this style bulkhead fitting with Dowty washers ( Stat -O -Seals )

if you've got access to the inside of the tank.

Search for "bushing, Tank Fuel"
Older bobcats used a 124253 part number.

Looks like a bulkhead bushing you could pick up at Harbor Freight or any auto parts store.

Thats what I tried, that's what the bushing on the brass sleeve in the picture is. It lasted a few hours are turned completely hard and brittle.

If can't get the Miller part number, I'll try a pack of these off these fuel tank grommets off Amazon. The measurements all match so it might work.

And after 2 weeks of covid slowed shipping, I got a set. Thanks for the part number, I don't know why my LWS couldn't find it.
