99-04 fuel tank question

[flight_83]

My return style fuel system is almost here from Lethal Performance so I’ll finally be installing my fuel tank. Since I’m using the 99-04 style tank I’m assuming the single fitting is the vent. What is the double fitting? Should I just cap those?

Not familiar w/ your set up, but the single fitting is the vent and the double fitting next to it is typically the fuel pick up/hanger with your supply and return lines.

Yeah, the 99-04 has a fuel hat in the middle which is being replaced with a return style pictured below. I’m pretty sure I’ll just be capping those vents off.

Hey guys, I posted this a month ago but because of the holidays I haven’t followed up on it or been in the garage much. I’ve been trying to figure out what to do with these fittings but haven’t been able to get find the answers. Again, I’m using the 99-04 fuel tank that has the fuel sender and level all in the middle. As you can see I already converted it to the return style but I’m not sure what to do with the 2 hose fittings circled in yellow? Should I just cap them off? I’m assuming the one circled in red is my vent fitting.
Secondly from my digging around the filler neck size is different from the earlier models. Logic says to just get the filler neck from the 99-04 and cut it similar to the manual but what are these lines coming off of it that I don’t see on the earlier ones? What would I do with them?
Any help is appreciated, can’t believe something so small is holding me up this long.
