The Stovebolt Site Forums The Shop Area Engine Shop In line fuel filters: are they really necessary??

My 63 c10 had fuel starvation problems, Upon pulling the fuel tank sending unit, I see the fine screen intake filter clogged with very very fine fine particulates.
That looks to be the culprit.
However, it made me wonder, with this lower intake filter, is an upper inline filter doing much? I mean, it would have to be a very very fine particle to pass thru and make it up to my simple old one barrel carb.

Really, I think that carb will never be affected by anything the intake filter passes on.
I don't like add on filters, they never look original and on this motor, placement - with original fuel line configuration- isn't that simple.
Opinions?

I run one on my '65 C10, cheap insurance against a simple issue.

dunno what the setup was on an original one tho'.

The fine particulates you are finding on your fine screen may very well be deposits. This means that some of this material is actually getting past the screen heading toward the carburetor. This material may currently be coating the inside of the tank and continue to be an issue in the future. An inline filter will give you added security, and a good way of discovering whether what I just suggested is actually occurring.

In my humble opinion, an inline filter is absolutely necessary in our old trucks, and offers cheap insurance against costly repairs. Even though a carb rebuild kit isn't expensive, my time certainly is. And you can't put a price on loss of performance either. Only possible reason for not using one would be if you had a brand-new fuel tank and new fuel lines, and even then I would still have an in-line filter just to be on the safe side.

Just my two cents worth.

Carbs aren't cheap but a filter is. I don't have a filter inside my 52panel tank but I have one coming out of it, and one between the fuel pump and carb.

....my 37 stopped on me while on I-85 one hot summer evening. Pulled the filter and was on my way in 20 minutes. Put them where you can get to them easy. Also never know what you get at the gas station anymore.

Agreed.

agreed x2

I have a new tank and lines and I still run 2 filters 1 before the pump and 1 at carb. root

"Never look original"? If you hide them in the frame, then you get the look you want. DADS50 has a cool filter that threads onto the carb as sort of original. WIX 33081 or equivalent.

The period correct filter would be a glass bowl type

Lonniec has a thread with good info and pics


I run a filter under the tank,
Was having flooding issues so added a second at the carb
A recomendation from a member here

Hid one of my filters to the flex line on the chassis.

...I plan to stop at O'Rielly's tomorrow for the Wix 33081 for my 261 in the coupe. I checked online and think they have it for $4 if I remember right.

Where was the period correct filter mounted?

The nice part about the original style glass bowl fuel pump was it has a screen that prevents alot of particles from getting through to the glass bowl fuel filter at the carb. If you have those to items, I do not see a reason to have another filter between the tank and the pump.

If you don't have the screenage at the pump, it's a very good idea to use an inline filter before the pump.

Thanks. It always seemed that the filters mounted right above the hot exhaust manifold was not the best idea. They do look nice though. I have a few, but do not have the will to cut my fuel feed line.
