Some of the inline metal filters have a paper filter element inside, blowing
compressed air through them can open voids in the paper making them useless.
But in a pinch and your stuck I guess there nothing you can do. Russell makes
a very
nice billet aluminum inline fuel filter that has a brass filter that easily
cleans up in the parts washer.

Subject: Re: [oletrucks] re: tune up
Patrick,
The other afternoon I was driving my '55 1st (Original carb.) and it
started to buck and would'nt go over 45 or 50 mph. When I would let up on the
gas it smoothed out, but when I tried to go faster it started bucking again. I
got it home and checked the points, plugs, and all the wires. I had rebuilt
the carb about 2 years ago so I know it is o.k. Then I took off the fuel
filter, and sprayed carb cleaner in it and gave it a shot of compressed air
and a bunch of crud came out of it. I made sure it was clean and put it back
on. Now my truck runs just fine. Try that on yours, or get a new fuel filter.
It might just do the trick! The filter on mine is the inline metal type, not
the glass bowl type.

Barb asks: I am trying to fine tune my 49 GMC 228. It runs pretty good but
while
idling every once in awhile will backfire thru the carb...
I too experience some carb farts every once in a while. But not while idling.
Only when accelerating hard. Its usually when the engine hasn't fully warmed
up
to full running temperature and I hit the pedal. Usually backfires through
the
carb are an indication of a 'too-lean' mixture. If you backfire through the
exhaust, your mixture may be too rich. Mine is a Rochester carb. I haven't
pulled it to do a rebuild or check the size of the jet(s). I don't even know
if
there are slow and main jets in the thing.
The other condition I have experienced is that it runs much smoother from a
stop
and when accelerating out of a gear shift if the choke is out a little. I had
the throttle hooked up but the pedal kept getting stuck and I'd have to reach
down and pull it back, so I dis-connected it. So I wonder if the carb back
fire
and the general smoothness of acceleration are connected symptoms of a overly
lean mixture.
To top things off, for the first time in a year I was driving home when the
engine started to stumble like it was running out of gas and quit. I sat for
probably no more than 30 seconds, started it back up successfully and drove
home
without a problem (about 12 miles). This has happened twice. Plugged fuel
filter? Faulty pump?
