sediment bowl filter

I just took off the sediment bowl on my new to me 74 vintage a4 and it has a filter in it in bad need of replacing. The bowl was nasty too. I thought all they had was a screen. Anyone seen these filters before and know where to get one or what should I do? It also has a gram water separator filter on the bulkhead that was recently installed before I got it.

Sorry about my spelling. Darn not so smart phone. I meant fram filter. I can't find anything online looking like the one in the bowl. It is about an inch deep and has a gasket on top with holes around the edge and the basket dia is about the same as the bowl gasket. I just left It out and put in a new bowl gasket since so much junk was in it. There isn't a screen in there that I can feel. Do you think I am ok since it has that big fram filter? It now runs like a scalded dog after cleaning all that gunk out so I'm happy. The bowl had not been cleaned in at least 8 years I'm sure.

Smile 2 filters??

Do you have 2 filters. I'm not sure if I understand you correctly. If you removed the one closest to the carb and it had debris you should change all filters. If you cannot find the same type put an in-line filter in just before the carb.

Pics would be very helpful if you can put a couple on here so that we know exactly what you are up against.

It has a new in line big water separating filter under the tank then inside the original fuel pumps sediment bowl there was another filter instead of a screen. I just changed the big filter last week and it was clean. This week I decided to clean the bowl on the pump and found that filter in there. Never seen anything like if before.

rrranch...I have seen a few other reports of A4's with a little filter in the sediment bowl of the manual fuel pump. I dunno where to get them either. I think that Moyer's solution is simpler, personally. I tried for a while to get a little filter to fit the bowl, and gave up and with the tried and true small self contained canister filter that Moyer sells.

Someone else can probably help you with the Fram....there are a few guys here running the Fram filter.

(Psst..I think you can turn off the auto-correct on the spelling thing on your phone, except unless it is an iPhone.. )

I think that fram is working ok. The filters are easy to get. I. Want the one sold here too though. I use that brand on my tractors and it is great. I'm using a Droid phone and never thought about turning off the spell checker. Thanks for telling me.

I have a A4 with a glass sediment bowl with a filter inside.
Are these still legal and is there a replacement filter. Everything looks good but filter is discolored.

rrranch, every Android phone is a bit different, but mine is in the "Language & keyboard" section under settings for the device itself. There are separate check boxes if you have real keyboard & an on-screen keyboard.

New sediment bowl/washer, screen and Bale. Not good !

Today I installed my shiny new parts to replace an original old set of same.
I could not get the thing to seal properly and it leaked gasoline dangerously. Tried every combination of re and re you could imagine and it made no difference. The new rubber seal is thicker than the original and the new bale has trouble staying centred on the bowl bottom and this may be exerting uneven pressure around the rubber sealing ring.
Have I done something wrong - can someone show a cross section of how the parts should be assembled ?

Fuel pump sediment bowl issues

Shrek, we see this quite a bit on older fuel pumps. The housing just above the sediment bowl bows down a bit from years of over tightening the bowl bale. If you dry fit the bowl with no gasket/washer you'll probably find that it rocks back and forth a bit over this low point on the housing. If the housing doesn't drop down too badly, you can pick up a coarse 2" sanding disk at your local hardware store with adhesive on one side, stick it on top of your bowl and work the bottom of the housing till it's flat. OR, you can smear a bit of JB Weld on the housing, then install the new washer, then install the bowl but only tighten the bale a little bit until the JB Weld sets up overnight. OR, you can buy a new upper housing from the fuel pump section of our catalog that is much stronger over the bowl than the original housings.

The original brass screen is not too important as long as you have a proper primary filter and an inline polishing filter between the pump and carburetor. The tiny filter you found in your bowl is an aftermarket device that is also really redundant as long as you have good primary and polishing filters. Don

Sediment bowl

Shrek, a finessful step to the above procedure would be to cut a disk out of wax paper and slip it between the JB Weld and the washer during assembly. This will usually enable you to change out the washer in the future without disturbing the JB weld layer. Don

Thanks Captain Don

Thank you for this timely response, and for this forum of wonderfully supportive members who have given me much help and confidence to assist me as I continue to renovate and upgrade my Columbia 30 (1972) #036.
I think I struck gold in finding one member, Neil Dutton, who actually worked on the production line, next to the one where my boat was built, in the Costa Mesa plant in CA.
Have you ever thought of trying to bring all of the members together for a weekend event which would allow us to "actually" meet one another, and perhaps showcase your business and its products first hand ?
I wonder how many members would like to respond to this idea?
I will heed your advice re. the sediment bowl as I continue full steam ahead with my Atomic powered sailboat ! Who would have ever imagined, an Atomic powered sailboat !

Those Fram filters are from an old style sediment bow that Fram supplied to the aftermarket it was called a 1/8" sediment filter as I recall and had a glass bowl. It is virtually the same size as the filter/sediment bowl on our A-4's the only difference is the depth is about double on the A-4.

There are still filters available, what you described is an old style. The newer style looks more like a "bunt cake" pan in miniature.

Gordon, as a bit of insider information and for a little fun, keep your eyes open for a Coronado 32 center cockpit. It is the same hull as your Columbia 30 with a 2 foot bustle added to the mold and of course a different deck. Look carefully and you'll see the vestigial seam line on the hull side where your transom is located.

At least one member has modified his mechanical fuel pump to do away with the sediment bowl, drilled and tapped a new fuel inlet into the pump body.

to clarify!.........................

I never had anything inside my sediment bowl when I opened it up. I seem to have caused some confusion by adding to a thread already started by someone else. I believe Don has given me the likely solution to my problem.
I have now discovered I have water in my fuel. Ran fine for 4.5 hours and now will not idle. Emptying the tank and main 25 micron separating filter today. This is all I have, at present for a filter and would like to replace it with a 10 micron and a polishing filter between the pump and carb.
