tried to do some searches to see what people are using for fuel filter upgrades specially with boosted carbs but cannot seem get the info I wanted. I still have a stock fuel filter for the 12a on mines and I think It should be upgraded since my fuel pump and carb along with a camden are aftermarket . how bout a K&N? such as this

Good idea. I'm upping to a bigger fuel pump and was wondering if I had to switch filters. Although, I'm not opposed to using the $3 filter mazda uses. Seems to get clogged a bit, but that just means it is doing its job. It is cheap and easy to replace.

That's all you have to do is add another inline filter before the carb for extra protection. :-)

I presented this as an option a while back, using dual filters in parallel. It turned into a pretty long thread, and a lot of other options came up. Lots of information on aftermarket filters, specialty filters, etc. Check it out....

I'm running two stock filters, one before the pump which is a 7Lb Carter, and one before the regulator. If the first one lets go, The second will catch all the debris before it goes through the reg and my Sterling. I also change them every April before I get the car back on the road.

interesting. So the stock fuel filter is good enough for upgraded fuel pumps

In my experience, the stock fuel filter is just barely adequate for a stock pump and carb. That's why just a little bit of a clog will cause issues.

Running two filters in line might help protect your carb, but will only increase the restrictions. That's why I ran mine parallel, meaning I split the line into two directions and installed a filter on each line, then joined them back up again. That way each filter only has to flow 50% and I still get 100% flow to the carb. I haven't had to change my filters in two years now (although they will be changed this spring just as a preventive measure).

Some of the other filters in that link I posted are actually high volume filters, which would achieve the same objective with less work (but more cost).....
