let's talk fuel filters

What do you guys prefer? Paper element or screen? Canister style or log type? Any flow better than others? Any suggestions on wether carbs are more sensative to particle contamination than fuel injection? Does it pay to filter down to 10 microns if the carb won't care until say 100 microns? I know everyone has their favorite brands for fuel systems, but what are the generalities when selecting parts? I am considering adding a fuel cell and redoing a section of my fuel system including the filter.

Well I use a canister type with a replaceable paper element which is rated at 40 microns. As far as microns go I've seen them from 100 on down to 8 microns. The significance other than extremely clean fuel and bragging rights from a markets standpoint I ve personally seen no difference. Most of the people I see run between 40 and 80 micron filters with out any problems. The best advice I can give you is make sure the filter is rated to flow the same or more Gallons Per Hour (GPH) than your pump. In other words if your running a 140 GPH pump make sure the filter is rated to flow 140 GPH or more otherwise it will become a restriction. I think the shape is a matter of perference but if space is restricted this may dictate the shape. IMO the Log filters make for a cleaner looking install though, which is why Im switchin to one this year.

What Doc says makes sense....

I always buy expensive filters...I think you get what you pay for...so buy the good ones.

Right now I am using a new factory tank and a Russell filter with a Holley Blue pump. I was having fuel pickup issues, but I fixed them today. The puckup tube was a little too long and was sucking tight to the bottom of the tank. I also have all new braided stainless hose. I am still concerned with the -6 line coming out of the tank to the filter. The rest is -8.

Your backwards, you need to run -08 from the tank and 06 up, using a small supply line to a big feed line slows the reaction time of the fuel demand and can lean you out.

Here's a nice set-up for a mechanical supply system to about 400 HP, the billet filter flows at about 120 GPH with a lifetime, cleanable, SS, 40 Micron Screen. They run about $50 but it's the last filter you'll probably ever buy.


100 Microns are chunks, 8 microns are almost undetectable by the human eye and would only be used in a clean room at Walker Siltronics. Be very careful of those little, glass, screen type, inline filters they flow very little, they're for a stock Honda....not your American Muscle V-8

WHAT WOULD BE A GOOD SET UP FOR A 400-500 HORSE MOTOR WITH A MECH. PUMP. I JUST GOT A RACE DEMON TRING TO FIGURE OUT A NICE SET UP WITH A FUEL LOG, PRESSURE REGULATOR, GUAGE, EXT. SHOULD I RUN NEW LINES FROM THE TANK TO THE PUMP? WILL THE STOCK LINES BE TO RESTRICTIVE?


THANKS FOR THE FEEDBACK..
