I'm trying to find a way to run the fuel lines through the frame without usimg the fuel line, anyone know of any fittings I can use so rubber line don't have to go through the frame, I'm looking at something 3\8" for a fitting.

When aircraft fuel lines go through a metal firewall (frame), a firewall fitting is used. it has a hex shape flange on one side to butt up against the firewall, and threads on the other side for a nut to tighten up against the other side of the firewall. each side of the fitting has a male flare, which connects to a female swivel on the end of a fuel hose.

here's a pic. there are a variety of styles and male ends. They come in straight, 90 degree, and 45 degree angles.

Ya that will work, so I wonder if they make the ends barbed instead of threaded? Anywhere you know of to buy locally?

Just for those that might not yet know, JIC and AN fittings are the exact same thing, with the exception that AN, which means ARMY-NAVY, are of air-craft quality, whereas JIC is not necessarily so precise.

For all practical purposes, JIC is more than sufficient, with no real reason to pay ten-times the cost for AN. ;Really

For these bulkhead fittings im kind of confused on what size I need, do the sizes shown show the thread size or the opening size. Im not sure how my fittings are measured, I bought a 3/8" Barbed fitting, is that the thread size or the barbed size?

3/8" denotes the ID of the fitting, and in the case of a barbed fitting I guess that would also be the size of the barbed ends.

The actual ID of the hose and OD of the fittings can vary by manufacturer. As far as what size hole you'd need to drill...1/2" is most likely what you need, but you probably should wait until you have the fitting in your hand.

JIC fittings are labeled in sixteenths; thus an 06-JIC = a 3/8" I.D. fitting; 08-JIC = 1/2; 05-JIC = 5/16, and so forth and so on. ;Really

If you're going to work with flare fittings, keep in mind that aviation fittings have a 37 degree flare, and fittings used for most everything else have a 45 degree flare. A good mechanic doesn't mix the two. Of course, I've seen it done before, by guys who pound a square peg into a round hole, and are proud of it. IME, mismatched fittings eventually leak, and retightening the nut only delays the next leak.

Aviation fittings are aluminum to shave weight, not really needed in your application.

I've heard of these goldenrod filters before, what makes them special exactly? Prefiltering out sediment? 10 microns is pretty good so is this an additional filter or to replace the kit?:dunno

The bulkheads are those the size I need?

Wont I also need a coupling since one side of the bulkhead is a male thread and the other end is female end?

BOTH AN "aviation" and JIC are 37* flare and will mate properly as I already stated, just so we don't confuse any of the un-educated. :)

Standard plumbing flare-fittings are 45*. ;Really

So I saw mentioned earlier that galvanized fittings were a no-no with diesel...what about zinc plated steel, are they ok?

I can't state scientifically either way whether galvanized and diesel are compatible or not; but, many is the underground tank that has underground galvanized lines feeding the fuel-pumps, plus the vents and such are always galvanized. :dunno
