Gas Tank vent

[Thomas Gayer]

Dennis or Steve,
Can you tell me how to vent the Lone Star Gas tank on my cobra?
I did not use your lemans type metal filler with the screw on the side. i used a mustang filler. Basically i need to know how to get gas into your big mother tank without it boiling back out like a volcano. I'm going to do my darndest to have this puppy running with a 427 by March for TCC meet in Round Rock? i have a 302 in it now with a 600cfm Holley Double Pump and it runs ok. i will have an 800cfm Holley Double Pump on the 427.
also can you recommend and external EFI pump for the GT40 I'm building in the garage, it will have a little over 400hp. I will put your lemans type filler on the GT40.


thanks
Tom

There are two vents on top of the tank. They are Brass inserts.

One is for the pressure regulator return line and the other is the tank vent tube connection. I recommend using the one close to the sending unit mount as the filler neck vent.

Did you install an access port in your trunk? If you did, all you need to do is run a piece of rubber gas hose from the brass fitting to the small tube on the side of the fill tube. If you did not install the access port, drop the tank and connect the 3/8" hose that way.

If you do not have a vent tube on the filler neck, make one,

Hope this helps.

i had the small vent tube at the top of the filler neck and ran a rubber hose from it to the top of the tank, but now that i think of it that would not vent anything. i guess that other barb was for a fuel injected return from the motor. i will plug it off and run the hose out the back or should i run it to a charcoal box. i have a couple of those laying around. thanks for the reply, the tank does not have foam in it but i plan to get a few blocks from Speedway Motors.
