Came up with this after reading and seeing how easy rust will settle into the fuel line.
Cheap and easy to make. A bit trickier to install! But do-able.
Two pan magnets from automatic transmissions, and I cut open and old automatic transmission filter, for the fine brass mesh.
Any transmission shop will have this stuff laying around and probably give it to you for five bucks.
Cut the mesh to fit, put it between the thin magnets, push it up with your finger to create a “hill” so rust won’t settle and clog the screen. Hope it helps someone.

What a great idea and thanks for sharing. Now I will have to go find a auto trans shop and see if I can get the items. 

Is sure would work good in my 45 2A.

Have a great Holiday weekend,

Frank

How will this work better then a servicable filter located right past the tank? Summit racing and others sell 40 micron stainless steel mesh filters that can be opened up and cleaned. I have one in my fuel line with a valve between it and the tank that allows me to service the filter with minimal loss of fuel no matter how full the tank might be.

If your in tank filter were to get plugged up how would you service it?

It probably wouldn’t work better. But, if you tank is pretty rusty, it’s fairly likely you’ll create a leak attempting to install the 40 micron filter ( that will likely need service often if your tanks pretty rusty)
But for five bucks and five minutes, maybe someone’s  jeep will stay running long enough to plow the driveway or whatnot.
Not trying to reinvent the filter to make a million. Just an idea.
Happy thanksgiving

A creative idea for sure, but I don't see an advantage in placing a screen inside a rusty tank where it will be difficult to service.

I would address the rusty tank first, either by cleaning and sealing or replacing. Nothing more problematic than rust in the fuel system in my opinion. 

I would also have at least one good filter that is accessible for maintenance. I like the Carter glass bowl filters with the ceramic element and I mount them at the carburetor. On my CJ5 I have such a filter, with an additional canister filter mounted behind the floor riser. 

I used to fool with cleaning out old tanks, but after mixed results, and a long walk home a few months ago, I prefer to replace a questionable tank, especially if it is rusty inside.

New CJ2A gas tanks are cheap - under $200 and easy to install. I'd much rather just put a new tank in and be done with it. 

1948 CJ2A - It goes nowhere fast, but anywhere slow.

  I can see that it has good qualities and bad, but it is an ingenious idea. I have had fuel delivery problems in the past (that’s how I learned so much about them) and can see where this might be a good solution, even if temporary. I missed a day of FCT years ago because of a rat-turd sized piece of silicone sealer that kept plugging the outlet when the fuel level was low (you all know damn well that I was not responsible for it being in there!). This screen idea would have allowed me to enjoy the day’s run. I can see where if one had flaky rust in his tank this would allow him to enjoy his jeep, and if he cleaned the screen on a regular basis he would eventually collect up all the junk. The problem as I see it is as has been mentioned- How do you install it, and how do you service it?

So obviously, it would be way better to buy a new tank. And for a lot of Jeep’s, that means new straps, some anti squeak, likely new lines if original,maybe cutting out the seat bolts if rusted solid. and etc…so likely not 200$ and an hours work.

I’d originally tied to come up with a nylon thimble type that sits in the I.D. Of the drain hole. (Think any “modern” motorcycle tank) But couldn’t make it happen easily. So I did this.
My tank is new. So if you were to do this on old rusty, I’d put a magnet in a sock, affix it to a flexible stick (tent pole perhaps) and run the sock magnet around the tank to clean up the loose stuff first.
To install, I had some some old plastic bed liner pieces cut into strips I had used for a project long ago. One down the tank neck made for a nice ramp to slide the magnet deep into the tank.
I then used a large speaker magnet to drag the “filter” home.
    The mesh screen, although fine, isn’t likely so fine as to clog up, and the 1/2” bump the screen makes, should keep it clear enough to flow what the pump asks for.  
I get crafty out in the garage, and figured what the heck!
    So this isn’t better than sliced bread. No.
But it is better than burnt toast!
