Despite a Fram G-2 gas filter on my car,(about to be changed out again) I'm having a problem with dirt in the carb. (previous posting) My duel diaphragm pump is the type with the glass sediment bowl on the bottom. If my memory is right (it often isn't!) these originally had a filter in them, possibly a ceramic one? In any case, are filters and gaskets available for these pumps?..Thanks.

No one can help me with the fuel pump sediment bowl filter question? Any info appreciated..

I will give it a try, my 55-56 parts book lists the following

1955/56 Pass car fuel pump B5A-9350D

1955/56 Pass car Strainer B5A-9365A

1955 Thunderbird Strainer B5S-9365A *

1965 Thunderbird Strainer B5Q-9365A *

*not part of fuel pump

Concours parts Car (not Thunderbird) 2008 catalog lists 8A-9365 as  "Filter-Fuel Pump"

The catalog picture shows a paper element filter and looks more like the larger Thunderbird filter that was located at the top of the engine just before the carb, not on the pump as the pass cars.

The car shop manual also calls it a strainer but does not show a picture. I have never seen a pass car pump with a filter in the bowl but both the shop manual and the ford 55/56 chassis parts book say "Strainer"

A Google search on B5A-9365A gets 2 hits only 1 having a picture but it also looks to large to fit the pass car bowl.

So does it exist, it did at one time but I am not sure if you could find one today.

The only filter the original Ford pumps had was a fine meshed brass screen or strainer above the sediment bowl . The later Ford pumps had a rockwood filter. The early 60's had a metal canister below the pump with a cartridge filter inside. Some of the after market pumps such as Carter had a paper cartridge filter.

What make of pump have you got.

There are a few issues going on, here.

What year is your engine?

Why do you have so much dirt in your tank?

Why not use an in-line filter (or two in parallel), so you can see the dirt.

I don't understand how all this dirt is getting past the screen IN YOUR TANK, unless it is coming from your steel gas lines.

Notice, we keep getting back to your fuel tank.

My '55 Customline tank yielded FIVE heaping handfulls of rust.  Rather than messing around, I bought a new tank with the proper tin coating, and installed stainless lines.
I opened the old tank with a torch.  It was a mess.  Witness marks revealed lots of varnish from gas left in it for many years.  The sides looked like the Grand Canyon with different levels of varnish.  The liquid level sender unit was shot too.

Whether you take the tank out or not, you need to flush it clean.  I would use a garden hose to keep the junk in suspension, and a pump.  If you get all the fumes out, you could use a shop-vac.  Do it in the middle of the back yard, in open air, far away from buildings.
When you are done removing the water, pour in some alcohol and slosh it around.  Alcohol sucks up water faster than Scotch, and it is easy to remove.  Even if you don't get all the little dropletts out, alcohol mixes with gasoline.  It WILL come out.

Hope this helps.  - Dave

I buy repop gas tanks. It saves a lot of headaches.

I can't believe you are still around to write your hints if you opened a gas tank with a torch!!!!!!!!!!!!!!!1

There is a glass bowl filter for Flat Head V8's.  I bought it by accident once, it looked like a mini air cleaner filter.  It fit inside the glass bowl on my fuel pump.  I couldn't find any literature on it, and it didn't seem like it was supposed to be there so I never used it.  Might have been from MACS.  I've always just used a steel inline after the pump as a safety precaution.

I would be concerned about where the dirt is coming from.  I used to have so much junk in my gas tank that it would clog both the sediment bowl and the inline fuel filter, and the car would stall out while driving.  Even with all that, I never had any dirt or rust get to the carb.

John, there ARE safe ways to do this.  Yes, I used a torch with NO consequences.  Old tanks can be welded and modified. 

I fabricated and installed a 'dish' inside mine for my (Mustang) EFI fuel pump.  Some guys do this outside the tank, but I prefer the modern method using a bayonet ring and a seal.  The pump works fine and the tank has no leaks.  If the pump ever goes bad, everyone has one for a Mustang.  It's a 10 minute replacement on the car.  - Dave
