Miller 2009 302 airpak fuel tank removal

[hammertimes]

The interior rubber of the gas cap disintegrated into my fuel tank. Keeps clogging my fuel line. I need to clean it. Trying to figure how to remove the fuel tank it looks like I need to disconnect quite a bit. It would seem you could lift off using the frame of the machine to to contain the guts but the Engine mount bolts,Air compressor lines and some wiring need to be removed? Anyhow, anyone ever have to do one of these?

Can you just substitute a MUCH larger fuel filter, or add a large filter to the line right out of the tank?

A better filter might be WAY better than risking disassembly of the welder,,
A large filter will easily capture the bits of rubber, and never have an issue,,

It’s clogging the inlet at the bottom of the pickup . No fuel gets to the filter. Pretty good sized chunks. But yeah I would rather not tear it apart

I was going to say use a shop vac but then I remembered that the fumes would be going through the fan motor with brushes arcing!

Siphon the fuel out. Let the interior get dry, then try to blow/sweep the crumbs to the fill side to get them. If you have a vacuum pump you can draw a vacuum on a container, then use a hose and valve to suck up the crumbs.

Yeah I was thinking about trying to suck out all the pieces. But don’t want to go kaboom. There is a similar question for a trailblazer 302 on the miller forum. Answer was unbolt the bottom tray and the tank can be pulled out after lifting using the lift eyelet. I stared at it long enough to figure that’s not how it works on the airpak.

I think this is really the only solution. I don’t see another way. Maybe tilt the machine somewhat and let gravity bundle up the debris, drain it and on the accessible side try to suck it up

There are air hose powered portable vacuums,,

Good to know. I will google. Thank you

It is called a venturi vacuum,, $36 on Amazon,,

I like the cute little black bag on the vacuum,,
Toss that, and let it spew the rubber bits wherever,, OTHER than inside of the tank!!

In a pinch you can use a length of 1-1.25" hose and a tube tipped blowgun, cut a small slit in the hose about 8" from the discharge end and insert the tip into the hose in the direction you want the junk to flow. Makes a pretty strong vacuum, used to use that trick to suck metal chips out of the bevel gear case on big dozers and other equipment. We would tape a burlap sack to the hose to catch the chips.

That’s a good one. I can totally see that working. I have the fuel drained I am going to remove all the goobers tomorrow and hopefully be back at it.
