OK I didn't search as long as maybe I needed to... Are you all whacking the stock lines off at the top of the fuel pump assembly and installing bulkheads? Or are you simply adapting the big line to the end of the stock hard lines that come off the pump? (You know the big 90* ones.)

On my metal tank sending unit, I cut off all the stock stuff, flattened it out. Installed a -10 90* bulkhead and a -8 90* bulkhead, all new 10 gauge wires for the fuel pumps and sealed everything up with a special 2 part epoxy. Still uses the stock sending unit and had the hanger welded to the top of the sending unit. I run 3 walbro in tank 255's.

Three? Holy dang. This is in my 94 so it's all metal. I will take the assembly out tonight and get a game plan. I was thinking the whole time I would be cutting of the stock lines but never saw anyone do it in pics. What do you think of brass/copper fittings from the plumbing store (they're about 1/3 the cost)?

AN fittings look like pipe fittings to me. I'm not sure on the flare part. It looks identical to me.

AN is 37*, common plumbing flare is 45*.
As for the other end:
AN fittings can be had with either straight threads, used w/ o'rings seals, [IE: fuel pumps, regulators, fuel rails, etc], or with the common tapered threads, such as used in hardware plumbing.
If you are referring to the threads on the flare end... the AN fitting may screw onto them, but the seal surface won't match.

I'm pretty sure Old Geezer is correct about the brass fittings being 45 degree. However, I've seen people use them with the 37 degree AN fittings. Myself, I like to do things right the first time. I'd just go ahead and get the correct AN fittings for the job.

I'm not quite sure what you're saying here, but AN thread does not = pipe thread.

I was saying the threads themselves are the same. I just wasn't sure about the flare part but just looking at them, they look the same to me.
