I appreciate all the ideas, but other than Ricks idea (which no one has done with a older Mopar tank yet), the small external sump tank, double pump system, I haven't seen a reasonable priced system and I would not use that on the street! With all the Auto X members I thought you would have solved this issue. Ricks tanks has this tank called a Vaporworx tank. It is stainless inside and out, lots of baffling, and get this multiple fuel pickups. In the Vaporworx ad Mary Pozzi (Auto x driver) tested this tank with much success. But it is stupid, silly, crazy, expensive!

I wanted to re-visit this post instead of starting a new one (I don't mean to hijack).
What is everyone using for a vent system?
I currently have a Hot Rod City Garage aluminum baffled tank (now out of business?) with an external electric fuel pump. I originally had a vent line routed into the frame rail and it just pissed fuel out (NOT GOOD!) So for the mean time, I've just capped it off (not good either!).
I've been doing some research... want an operating vent as to not cavitate/blow out tank seams with sealed filler cap so it doesn't spill fuel out the back, and I don't want the garage to fill with fumes.
Current plan is to run a vertically mounted in-line roll over valve to a II Much vent mounted in the truck (under the package tray?) at a level higher than the filler neck, with the inlet/outlet mounted externally. Other option is to run a Newton TPV6 valve. Should have about $300 tied into it when all said and done.
Thoughts?

Boyd welding has a slick little adapter plate that allows you to use a factory Ford vent on a custom tank. You could use the Boyd vent plate on a custom expansion tank. Build a one gallon expansion tank and plumb it to the existing vent on your tank and then use the Ford vent on the expansion tank. Or if your existing tank has a vapor dome in it then you could use the Ford vent right in the vapor dome. https://fueltankparts.com/collectio...ucts/ford-oem-vent-weld-in-bung-aluminum

Hotrod city garage, picture 4, of internal baffling. I don't think going to a external efi sump tank in California is legal. I don't want to go with a fuel cell either. This had a lot of features that some of the real big buck tanks have and are cheaper. It is also is made of aluminum. What issues, if any, might a aluminum tank might have? Any more thoughts about this tank? hope i'm not too late for ya - i have one - first the seal leaked as they used the wrong seal for gas (go figure) - would not send me a new one - had to make one up from the local parts store and cut out my own gasket - then had nothing but fuel issues spilling out of the tank - problem is the fuel pump is below the the top of the tank so it always wants to siphon - I had to weld a bung on top of the tank and on the filler neck and install a one way valve in it and add a seperate air vent with a filter on it - the tank is cheap and for these reasons...I bought through some one else (mopardan?) but it was built by hotrodcity garage I should also mention I used a hydromat when I last took out the pump

I'm going to check out the components that GM uses for their E-ROD packages. Since those are a retrofit to older chassis, that may be an easy route to take.

I use to design fuel tanks and tested them.. the first EFI car was the Imperial the group that did the injection didnt pay any attention to being low on fuel.. once they seen this issue we were given the project to fix it.. after a few weaks we came up with a can inside the tank.. over time we came up with a plastic reservoir in ALL production cars and trucks... still in all.. we called it a swirl can that would use the return fuel to keep the can full.. the pump is inside the can and will drain the tank to about 250 cc or less.. just look at the inside of a newer car or truck EDIT I also did a few company road race sponsored tanks.. they use to have a issue of running out of fuel so we put 4 pick ups in the tanks we built(one in each corner) being that these were carb system they never had a problem.. these tanks HAD to look like a production part.. we had to seam weld the seams on them

If the tank doesn't have a vapor dome then you will just have to remember to not fill it full. Or only fill it full when you are driving somewhere. The gas comes out of the ground tank at 60 degrees so on a hot day the gas will expand once it gets into the tank. Without an expansion tank the gas will just push out the vent. I ran into this same issue when I had a fuel cell in a race car. The fuel cell was just a box with no expansion area. I filled it up on a cool day and then on the next hot day I had a mess when gas started to push out the vent tube. This is what I’ve come up with to solve my vent issue. 1 gal fuel cell with built in roll over valve, plumbed using -6an PTFE hose. Should provide some sort of expansion for the fuel coming out the main tank vent port. Mounted on top it the IIMuch vent system. The vent system will then route to a sintered filter mounted to a bulkhead fitting. I haven’t finished mounting the 1gal cell yet but you get the idea. I’ve used body plugs as I didn’t want to drill any unnecessary holes in the trunk. Trunk will eventually be finished with removable panels. The IIMuch system came with a stick on thermometer that I mounted to my fuel tank and it definitely shows how hot my fuel tank gets here in Southern Georgia. [img]http://[/img]
