No overflow tank for fuel. Options

[Downerman]

So, after restoring this 73 and having a blast with the Renegade aspect (love the way it drives).... I have a bit of a problem. Never paid any attention until I started to drive the car and getting this gas smell. Well it didn't take but 5 seconds once I actually looked at the line off the filler. The guy (PO) had just looped the line back through the 1/2" nipple into the fuel spill area. So, here's my question. What are you conversion guys doing/running on your rides. Are you using the stock overflow and charcoal unit with all the vacuum lines? Some modified versions?? Would love to know.

Attached is my current setup. I'm embarrassed that I never caught it. Oh, and for those who care to know, I replaced that old line and fitted a new line and bottle catch to see if that was my source of gas. It is.....

Not sure that little guy will move enough air for you. It's spec'd for .57 CFM at .18" H20. Might be enough for a microchip in a laptop, but it's just gonna make noise in your car. Not sure exactly what kind of CFM you're going to need, but I'd shoot for something in the 2-5 CFM range. And 12 volts for sure.

I know..... .57 was exactly (or near) what I was wanting because I don't think the original fan push was much either. I bet I don't even hear it. Yes, getting from 12V to 5V is super simple and yes I checked my favorite place (Digi-key) and no I did not like the 12V blowers I saw. To much flow, larger and I would bet noiser.

For the record, with everything in place except the tiny blower, I filled her up. Ran it through the tests... (Left turn sharp, left turn sweeper and hard aceleration and stops and guess what? Not one wiff of gasoline.

Man I don't get this 12V thing. taking a device that runs 4-5 volts from 12V is nothing more than a tiny voltage regulator. There's a zillion sizes, types and brands. Oh well, to each their own.

No need to get your panties in a twist. Sounds like you are going into this with eyes wide open and have considered your specifications. We are simply trying to offer some advice and point out possible pit-falls later you could run into. There are many ways to skin a cat and you are certainly correct that a simple voltage regulator would allow you to run that fan off of a 12 Volt source. Please let us know how things turn out.
