Whats the general consensus on locating a inline fuel filter?
Before the fuel pump or after the pump.
I would think before to collect any gunk before it gets to the pump!

if you use the glass bowl filter it has a suction screen already in it. I used one of the clear filters with the cleanable screen in the suction line up until I replaced the entire fuel system though.

I always put one in the line between the tank & pump. Like you say its best to catch particles before they get to the pump. Its a good idea to have some kind of filter right at the carb also. It will catch anything that came off the lines or pump.

If you still got buggers gettin' thru all that, then
you got some real problems and need to seek
professional help.

Thanks looks like a trip to the flaps is in order.

I added a WIX filter a few years ago after I was having a flooding issue. One of the members here recommend adding at filter at the carb.
It involved making a new Fuel line , but that was Not an issue since I had the tools and left over line from the brake job.

Also have one under the tank ...pic...
Before the pump

My setup is the same as Denny's and I like having a clear one there to monitor any crud that comes out of the tank. I've never changed the element in the one in front of the carbs...it's more decoration than anything.

For a short time I used one of those clear marine filters under the tank

I could see the particles it was picking up
...pic...

But after a short while it starting leaking at the seals on the ends so I quit using it.

Here is the filter I tried

As did I Gus, and they are quite effective as you can see from
the sediment here:

Those are all made by Moeller and sold under a bunch of
different names:

I installed it soon after I got the truck in ’05 and had the
same issue with it that you did. Had to fight the leak every
time I cleaned it out.

I have to stand on Curt’s side of the line on the clear vs.
solid filters. If you’re running an old tank then it’s going
to continue to shed and you really need to monitor it. So this
spring, in fact just yesterday, I replaced the Moeller with a
clear NAPA 3002 inline filter. They’re not expensive, you can
tell for sure when it needs changing and it only take a few
minutes to change it:

You can already see it doing its job:

Thanks Curt and Denny, clear filter under the tank it is.
