Default Large fuel line exiting fuel bucket ideas

Ok guys, what do you have or what have you seen in order to get large fuel lines out of the stock bucket? I'm running twin in-tank pumps and upgrading the entire rest of the fuel lines, but it seems pointless to upgrade all of that and still have it sipping out of the tiny straw connecting the fuel pumps to the top of the bucket.

I'm trying to come up with a way to run two -6 lines (one from each pump) through the bucket bulk head, then on the outside connect them in a Y and on to the -8 feed line I'm running. I need to keep the stock functionality of the evap system, as well as the stock return line. I would also not be opposed to running the Y inside the tank and doing a single -8 out of the bulkhead.

I have seen a few pictures of these setups but they seem to have different bulkheads than my bucket does.

Saw a post by trtturbo with this setup


From another thread over on ls1truck, I saw this setup

The problem is, my pump bulkhead looks like this


Ideas?

I'm not real sure where the evap goes...that looks like two feed lines and a return, with no evap. I need all of them.

Could you just vent to atmosphere?

I want to keep the evap system on here for this reason...this was posted in another one of my threads.

I could only fill it at a rate of ~ 1 tank an hour because it would keep burping out. For a temp fix I put a AN bulk head fitting into the top of the tank and a AN check valve and run a vent hose high up into the quarter panel. This still sucked and caused burping issues. I then hooked up the evap line straight to the intake with no evap valve and when I'd fill the tank it would burp fuel into the intake and flood the living hell out of it. It took ~2mins of reving it to be able to move and gagging everyone at the station. So I hooked the evap solinoid back up. If I was to do it again i'd use the bulk head fitting as the return and don't touch the evap. Just causes issues.

Have you looked at the surge tank ideas? I like the idea of leaving a stock type pump in the tank that keeps the surge tank full (1 gal?) and still getting to run a huge inline from the bottom of the surge tank. Unless you are doing 1 minute WOT runs I don't think your surge tank would run out.

The Evap/Purge System actually pulses a predetermined vacuum to the fuel tank to check for leaks.

That's what's next for me.
