The Stovebolt Site Forums The Shop Area Engine Shop Can you have too many filters?

So I am working on getting my 49 set to start up and break in my newly rebuilt engine. I know that my gas tank is not in pristine shape. So my question is this can you have too many fuel filter in between the engine and the carb? So here is what I am thinking of running. Right after the down tube from my tank I am planning on running a G2 fram Gas filter (Clear Plastic so I can see the major Crud) and then on my Fuel pump I have a filter. I also have glass bowl filter ( but have never used it) that would go right in front of the carburetor. Am I being too crazy about keeping the junk, that I know is in my tank, out of the fuel pump and Carburetor?

Better have a spare to change the one closest to the tank when it clogs.

Don't use a known cruddy tank. Get a new tank for something like an outboard boat motor or even just a plastic gas can, and plumb the fuel system to it. Old gasoline residue and varnish will be dissolved by the fresh gas and it will go straight to the valve guides. The SECOND time you start the engine, you'll have a bunch of stuck valves and/or bent pushrods. Enough crud will get deposited in the valve guides during the first run to trash the engine on the next attempt at starting after the engine has a chance to cool down. It's happened many times to several stovebolters.

You need to address the tank issue sooner or later so either replace the tank or clean and seal it. A new tank from Classic parts is only $209 plus shipping and that eliminates the issue. That way the only filter you need is the one by the carb.

To just get the engine running, do as HRL suggested and run an external tank.

During a break-in run, the last thing you want is to be shutting it down to keep cleaning and replacing filters. Once running, let it run for the duration. Also keep water hose handy to cool the radiator, same thing applies here, keep it running! 3 gallon plastic fuel tank/jug and some rubber fuel hose, problem solved.

Why wouldn't you spend $200 to buy a brand new tank? Seems like you're stepping over a dollar to pick up a dime.

I installed a new tank from NPD in my 1950. It's made in Canada and is better quality than the original.

Well I really appreciate all the feedback. I learned something new today. I will order a new tank and if I have everything else complete before it gets here I will run a temporary tank to break the engine in.

Buy the new strap set to go along with it. You'll also need a new outlet/petcock valve and sending unit.

There is a new sending unit available on ebay that JonG recommends.

I should mention (as I've done many times here), if you need a new sending unit the most accurate and probably the most long-lived one is sold on eBay by a seller whose ID is renbusan. About $30. I think he may also be selling the sender on Amazon. Made in Taiwan and extremely well designed. I mentioned it on page 1 of this thread, but I mention it again in case anyone needs it. Jon G

Yes, that's the one made in Canada by Spectra. Less expensive than the same tank from NPD.

Thank’s Otto. That is good info!

After you get the new tank and shutoff valve installed, you might consider plumbing in a glass-bowl filter immediately after the shut-off valve. That will catch water and keep other nasty things out of your fuel pump which eventually will probably be electric. If there is water you can see it and dump it. Check occasionally. You can get water from condensate in the tank or pick it up from storage tanks at the gas station. If you live in a humid climate, keep the tank full if you're not driving it daily.
