Sintered brass fuel filters. Good or bad?

[ebinmaine 70,735]

Mods, feel free to move this if it isn't in the right section.. 

 

The Kohler twin that I have here had a sintered brass fuel filter with a sediment bowl. Just wondering I want the ups and downs of that type of fuel filter are? I know that they are far from common nowadays. Did we switch to paper simply because of cost savings?

Eric,

   Most likely cost.The one thing good about a sintered filter is that it can be back flushed and reused.When common they were just chucked.

Sintered brass fuel filter with sediment bowel frequently used on commercial grade applications while the paper element types of fuel filters are aimed at the domestic crowd.

Sintered brass in the carb bowl? Eww!! I would chuck them. It sounds like someone didn’t flush them..

I don't see where anyone got brass in the carb bowl.

 

I think we are talking about sediment bowls like this one:

 

 

They commonly screw onto the bottom of the fuel tank and have a screen and brass filter in the upper portion.

How would one go about doing this and what chemical might be used?

@adsm08 is correct.

Take a peak at my thread about the K582 in the engine section. It shows the assembly.

That would make some sense.

This one was on a K582 which was likely on a commercial generator.

I'd think it would be a simple matter of hooking it up to a pump and running some gas or mineral spirits through it backwards.

Or carb cleaner.

Oh, I have one of those. Ok!

Eric,

    When your genny was built there were very few if any paper fuel filters on the market.Commercial or homeowner was not an issue.You had a filter or none.Today even commercial users have paper filters.Check any commercial application and you will be hard pressed to see anything else these days.Think about oil bath air cleaners.You don't see many modern uses of that technology except heavy trucks or construction equipment

When you purchase new equipment the buyer goes over the spec sheet, want a radio add or delete from list of options, want and oil bath air filter add to the list.

 

Buy used equipment then you settle for how the previous order was made when it sold or look for aftermarket options.

Eric,

   I guess you are stuck with what the PO checked off on the spec sheet 40 years ago.When you buy the next genny make sure to check off the metal fuel filter.it's option is on all lists!

Personally if sintered bronze were on the options sheet that would be my preference.

 

Fuel injection has changed the landscape.

Eric asked a simple question I gave a answer applicable to his aged equipment at the time of manufacture sintered bronze was an option.

 

I've also seen plenty of sediment bowels in use with out the sintered bronze, both Carter and Holley carburetors used a sintered filter which is hidden inside the fuel inlet.

 

And I believe these bronze filter used by Carter and Holley were eventually replaced with paper elements not necessarily because the were more efficient but based on manufacturing costs

Eric if the bronze filter is clogged with old gasoline turned to varnish, poly stripper is what I use on gummed up carburetors to remove varnish.

In 1977 I purchased a new 650 holley carb with a street dominator aluminum intake manifold for the 70 Chevelle SS and the carb did have that brass filter as noted by @bcgold, that brought back some memories for sure. That model carb had small primaries with large secondary's to try to squeeze a little more MPG. @ebinmaine I was not aware of the term sintered thank's for the info. The original carb was a Rochester quadrajet or what we called a Quadrabog, did you guy's use that term also?

Oh... We sure did...

When they were running good they were great... But then if they were in need of a tune or rebuild. Awful.....

[Stepney 2,350]

Acetone, mineral spirits, carb dip.. anything that will dissolve varnish. Blast it real good with air. Motor on for another sixty years.. 

I use sintered bronze sediment bowls on everything. Seems we often have issues with water in the gas, so the bowls help catch it.
