I have come up with a plan to repair my leaky 450 tanks.....there is an aluminum seperator plate between the bar oil side of the tank and the fuel side of the tank..... What happens is the tank will begin leaking and the fuel will begin mixing with the bar oil.....
Now the problem with attempting to repair the tank is the fact that the aluminum separation plate will get damaged to the point of non usability..... Mine was glued together with some kind of sealer and it was damn hard to split, even after the screws were removed..... Also on a side note, a lil heat from a propane torch will help get those screws loose....
What I am doing is working on making new separation plates , so far I have made a paper template, now I have to transfer the template to aluminum and cut it out and drill the holes.....

Heres a pic of the bar oil side , notice the divider , the upper section is for bar oil , the lower section is for fuel..... I plan to drill a couple 1/2” holes in the seperator plate so that fuel will be able to fill the lower cavity rather than cut one big hole.... Attachments:

I will most likely use Permatex Anaerobic gasket maker..... Its available through NAPA.... Its resistant to oil and gasoline... Its possible I may use the Homelite tank sealer.... Im undecided at the moment....

I have to measure the thickness of the original, then go pick up a sheet of aluminum.... Its gotta be close to the original thickness , otherwise some bolt holes may not align properly.... Just a quick guess, im guessing the original plate to be about .030 thick.... I will get an actual measurement and post the results....

Heres a pic of a partial piece of the separation plate, notice how it is bubled outward away from the oil reservoir.... My replacement plate will be flat, which will reduce bar oil capacity slightly Attachments:

Apparently I forgot to add the pic on my last post...... Anyhow in this pic you will see what remains of the original plate/separator.... my finger is pointing to the open, lower section, which is for fuel.... My new plate will be completely flat with some holes drilled, probably make four holes to allow fuel to fill into the chamber below the bar oil chamber..... I figure a flat plate will be stronger , especially on the lower portion of the fuel tank..... Attachments:
