Sooo was this costing me power?

I changed the fuel filter yesterday on my 88. It was just part of some maintinance I'm doing while it's put away for the winter. I never changed it after the fuel pump swap when I rebuilt the motor. There was some gas left in the old filter so I poured it into the tank for my snow blower (I wonder if it'll run better on 93 octane lol). I noticed that it came out really good from the inlet side of the filter but the outlet side was noticeably slower. Do you think some fuel tank gunk clogged the filter and I wasn't getting full fuel flow? Car ran great all summer. I'll have no way to compare the feel in the spring since driving the 95 all winter will make the 88 feel like it's got a 428 CJ in it:hick:

Yeah, the filter being plugged bad enough will make a definite noticeable difference in power.
My 92 F-150's filter got so gunked up, it would idle, but run really rough, sputter, overheat, and generally act like it was about to leave me stranded.
Bought a new filter, and presto, acted like it had a new engine, lol.
Some will say to replace the filter ever time you replace the fuel pump...might be good advice...

I kind of don’t recommend this cause it taste nasty but put your lips on it and blow if it comes right out it was fine. If you turn red you’re blowing too hard so it was clogged.

Gotta say I have tried that before I now some will comment

i always experienced with a new filter , it was harder to blow one way than the other.

I never knew why but I do know there is an arrow indicating fuel flow direction.  That being said,, if it was just a simple filter screen system, why would there be an arrow?

so...... theres gotta be something else to this.

is there a one way flap or check valve perse'?  I might be on drugs but i swear i remember a new fuel filter just feeling different one way compared to the other.

If I remember correctly, there is a valve inside that allows fuel to bypass the filter if the filter is actually clogged. That may be the reason it is directional flow.
It's Gumby's fault.

I got one that I bought for some dodge car that I will NOT drive anymore, I may take my dremel and cut it open to see what is inside.
It's never been used...
