I use this one on the vehicles that take 5/16, or 33033 if it's 3/8" line. I would never ever ever use one like is pictured in the first post on this thread, no matter what it looks like inside.
Ok here is whatI use first is a carter inline that has a cermic filter. the second is a wix inline those i always mount between the fuel pump and gas tank. the lastis the factory sintered bronze that mounts inside the carb at the fuel inlet. This i what works for me. watch one of those clear plastic filters when it is mounted between the pump &carb. the pulse of the fuel pressure will make it flex. Ive seen them rupture.
So what's the difference in the inline ones I posted and this one..... Besides people over tightening them and killing the threads. I've used these also, but sometimes they're too heavy for the span of the line.
My inclinations are to go for overkill on fuel filters after having, and seeing others have, problems with half ***ed fuel filters, and the inline plastic and cheap screw together gl*** ones were usually the culprit when there were problems. Although once when I had bought a new Holley 4bbl near the end of a racing season(dirt ovals) I installed it without discovering it had the sintered bronze filter slugs inside the fuel inlets. They dried out and varnished up over the off season and I had all sorts of fuel starvation problems till I found them! I used a large aircraft surplus filter with a cleanable SS screen that had both a cone and a cylinder shape combined for lots of filter surface area and capacity in my dirt cars due to the dirty conditions in the pits where you were refueling, etc. My hiboy has a trunk mounted tank with a large AFCO Racing SS screened cylindrical filter before the Carter elec. pump and afterwards is a frame mounted Fram Racing HP filter with a replaceable paper cartridge filter between the pump and pressure regulator, then on to carbs. Any filter using a paper or cellulose filter element should be on the pressure side of the fuel pump, as the paper particles can be ****ed into the rest of the fuel system if they are on the suction side of the pump and for some reason the filter element breaks down and disintergrates.
That filter wasn't made to be used inline in the middle of a span of rubber fuel line, it was intended to be rigidly mounted to the carburetor float bowl inlet using a pipe ******.
Curious as to how a careless move by a self-promoted expert could actually slice its own O'Ring upon tightening. Next move was to dub himself "MISTER GASKET"...
The difference is that carter is a high quality part made back in the day here in the USA. Its not imported junk. And i still dont mount it between the fuel pump and carb.
