Thanks!

Thanks! Any thoughts on what folks are using specifically for gasket material?

What are folks using these days for a gasket on the pickup tube? I've called four places and looked online. Are folks cutting a gasket from material? If so, what material are folks using? If the solution is making the gasket, I'm not worried about cutting out a good gasket shape but I want to be sure I'm using a good gasket material. Thanks!

Ha! That's interesting. All the fuel pump cares about is whether there is fuel in the tank, and not how much. All the carb cares about is whether the float bowl is full. So, if you have fuel in your tank and the pump can keep the float bowl full, you are good to go. The question is, What pump will it take to keep that float bowl full?

If the pump won't flow enough at the pressure it is pumping then you won't have the fuel to make your power! The question is whether the pump will deliver the volume you need at the pressure needed at the pump to create the pressure expected by the carbs. 30 GPH is more than you will likely need (depends on how much power you are making). However, as you can see from the chart, this Holley 12-428 pump, which is rated for over 30 GPH free flow, delivers less than half the flow at 4 psi which very likely is enough for about 130 HP in an engine with a 0.5 BSFC but not the almost 400hp that the free flow rating implies it can feed.

Hello all, I have done some searching on how to seal the air box and the door in the air box. What I am curious about is how long these solutions lasted. http://www.classiczcars.com/forums/open-s30-z-discussions/25172-changing-out-heater-core-1971-240z.html#post208917 For the door (in the thread above) folks recommended self-adhesive weather stripping for doors and windows as well as gluing a mouse pad to the door. http://www.classiczcars.com/forums/interior-s30/21508-how-seal-cowl-vent-blower-motor.html For sealing the box folks were recommending plumber's putty, dum dum, A/C tape, and foam weather stripping. Can anyone report on how long these fixes have lasted? I like the mouse pad idea. I just wonder how well the neoprene will hold up to the heat. Thanks in advance for the help!
