They still have to send me the pictures of the fix, but here are some pictures of the OEM swirl pot removed from the tank:





It's just a little metal basin with a slit in the bottom. So if you "toss" the gas out of the basin, it has to refill from that little hole. The basin also is flared outwards, contributing to the ease of throwing gas out of the surge tank.

The fix was a taller basin welded into the tank with check valves in the sides. The top is also flared inwards to help contain sloshes.

Factory fuel gauge fully operational.

Has anyone found a 'simpler' fix (i.e. one where you don't need to remove the tank)? I've installed my suspension, upgraded my rear this year...... no way can I go through that again, plus more, to get to the tank.

Someone mentioned a small surge tank and an external fuel pump - anyone tried it?

I run into this problem on hard left-handers when my fuel level is just 3 gallons short of full. I have to tank-up after every session, at this time.

I read the previous thread on this, and quite honestly it's above my skill level. Do not know of any local race shops in the area (NE Maryland).

The super easy fix is filler foam blocks like they use in motorcycle racing. But I've heard that stuff can break down over the course of a few years.

Just buy a surge tank & external fuel pump. You can route all the lines using your OEM fittings to/from both tanks. My entire setup, using this method, cost <$300. No welding required.

Care to share where you bought the parts? Which fuel pump did you use? Where did you put the surge tank? Got any pics?

Thank you!

Luckily, I've kept records of what I bought for this setup. Looks like I spent close to $450

CX Racing Fuel Surge Tank ($109)
Aeromotive A1000-6 Regulator ($135)
Walbro Inline 255 fuel pump GSL392 (115$)

To interface with the OEM fittings, Russell makes these inexpensive great adapters
Russell -6 male to 3/8" female p/n 640850 ($16)
Russell -6 AN male to 3/8" male p/n 640940 ($12)

I did this all on a MY06 which uses a returnless fuel system. Basic setup is that the OEM in-tank fuel pump fills up the surge tank. Then Walbro sources fuel from surge tank and feeds the motor. The 'overflow' fuel from the surge tank is directly dumping thru the OEM fuel tank plastic cover (which I modified with an extra hole).

Here's a quick diagram of the setup.

Since MY00-05 doesn't use a returnless fuel system, you wouldn't need a regulator right? The return would just feed back into the surge tank the same way the aftermarket regulator is feeding into it?

I saw in the other post someone was recommending this:

I like this solution because it is one contained unit, with the fuel pump housed within the surge tank. But is the Bosch 044 pump overkill for my use (AP1 with an exhaust)? Is there any downside on using a heavy duty fuel pump?
