Fuel Vaporization Using Eddy Carb -- In-Line Fuel Pump Question

cudaracer said
Here is what I know for sure. I previously had a clear plastic filter between the pump and carb, and after running the engine to temp, even on a cold day, I could come back in 15 min and that clear filter was bone dry and I would have to turn the starter for 5-6 sec. Happens every time, not just once in a while. Then someone suggested I should put the filter before the pump. So I got a new plastic filter, and put it about 10 before the pump. Nothing changed. I keep thinking I will soon have to replace my starter motor.

And I too question the carb design of a Holley. Does not seem to matter in my case. And that would be an expensive mistake to only have it recur again.
The vent back to the tank kind of makes sense, but I dont understand the physics of it all to argue against it.
Also,
Mancini Racing out of Michigan claims they sell a lot of the one way switch that has a reservoir that they claim is popular as a fix. Thought I could find it on their website, but I cant . I have to call back to find out what it is exactly. Anyone ever heard of anything like that?

Sounds like your tank isn't vented enough and when running the car your building up a vacuum in the tank causing the fuel to be drawn back into the tank from the lines when the engine shuts down. Check you fuel filler cap. If the cap is really old or original, it's worth the $10 for a new one.

Also, I'd like to address the few that are persistent on swapping "the Edelbrock clone" to a Holley. First, The Street Demon carb is not a clone, it is a completely new design. Second, Holley owns Demon Carbs, and has for the last decade, so if your shitting on Demon Carbs, your also shitting on Holley. That is all, thank you!
