Poulan plastic tank
« on: April 23, 2017, 01:39:54 pm »
Poulan plastic tank seal repair. 

Tank I was getting ready to ship. I like to plug them off and check for leaks.
There was a hair of seepage in the corner.  Not a leak as drips, just seepage making it moist over time if you know what I am trying to say.
So I went ahead and used the sealall tank sealant inside and out on that area.  I usually do the outside but was able to get to the inside corner too.
Going to let dry and test again after it gets set.
If you look how they are put together they are to pieces of plastic melted together by heat.

I always allow 24hrs before I check it after applying. Have used it on metal gas tanks etc in past years.

3.3 type 2 tank. Pulled and stripped bare.

This is the later type 2 ones with tank vent on side and only 1 line for fuel out top. 1997.

This one also excepts the big intakes like used on 330 380 3750 3450 without modifications to tank hole.

Setting with mix testing.


Day 2  I figured it would pass setting over night. It did no mix leaked.
