Repairing a Mantis tiller that hasn't been used in 20 years. Used to be a real little tiger and now I want to use it again. Bought new fuel line parts: in tank filter with hose, fuel line hose to carb.. The existing tank vent and hose still good and in place.

These hoses are 7/32 dia., soft and flexiblel and supposed to go through a hard rubber snap in plug in the plastic fuel-tank wall. How can I stuff the oversize flexible tubing through the smaller hole? It has to fit snuggly to not let gas leak out. How do the manufacturers do it? The plug is reasonally flexible, though fairly hard and should seal well when snapped back into place...did not buy a new one and did not see a ready-assembled repair assy..

I have tried spit and oil but there is no way I know of shrink the hose to push? it through the plug.

If you have ever solved this problem (other than sending the tiller to your repair buddy) I would be grateful if you told me how you did it. This system is an almost tweeser tool size deal.

IaLeo thanks you.
 
Cut the end of the tube off at a slant and then you can slip the end in and then pull it into what it needs to fit in. Trying to think of how to explain it better but not sure how to do that
 
Thank Mr. OLD, that trick worked! Using a needle-nose pliers, I crush gripped the tubing just outside the entry point after the little bevel-cut end got inside the bore. With spit lube, crushing and pushing and twisting, it got through far enough to be able to grab the bevelled end and pulled into position easily. I really appreciate your advice. Can not get it started yet, supposing the old carb may have problems, but you helped me solve this problem!

That is the way I do it. Works fine. I also have some long nose curved . Needle nose pliers they work great on getting around curves in the tank.
 
Always happy to help if and when I can. The place I use to buy my mower parts form would always cut the gas line that way so as to make it easy for the customers to install the stuff
 
I did the new hose and filter on my echo
weed wacker , by remove the plug from
tank put new hose through plug , then
push the plug back into tank

You can get a new carb from Amazon. I replaced one for my parents, and then my brother's mantis a few years ago. A year or 2 later my parents tiller seized up. Same gas run in everything else so not sure why. It had always been extremely temperamental so I'd be lying if I said I was too upset.

Air leak probably. Causes a lean condition and seizing.
 
Cut shape of the hose is the secret. Think about cutting it off square but don't do that. Angle your cut say to 45 degrees rather than 90
degree square cut off, then 45 of the 45 and so on till you have cut a long wedge angle in it (like ? inch long or so) such that only part of
the nose of the hose goes into the hole initially.

Push it in with your needle nose pliers and then from the other side grasp the end of this wedge and pull it a little with the same pliers, get
another grip on new material showing, pull a little more, choke up on it again etc. till you have a full tube diameter showing and pull all you
want; cut off the angle square and you're done. I have one of those little boogers and a real trucker. This may seem overly simplistic but I
have no idea as to your mechanical abilities so I made it simple so one can pick and choose what they want to retain.
