I need to vent the fuel tank I just built.
What is being used for a fuel tank vent? Something that allows air in, but won't let fuel out in case of a roll-over.
Is there a standard device? A line to a catch can? Coil of tubing?
Thanks!
Jim.

Fuel-Safe makes a roll over check valve. Several others also I'm sure. Check the advertisers in the back of the rule book.

Take the end of the vent line to an area that is protected as well as any other fuel line. not in a low pressure area, drains well, and ends up above the tank in an upset. A little baby filter on the end will keep out the same stuff you want to keep out of any other fuel line.  |

Jack, had a hard time doing this because we couldn't decide if the car would be on it's top, right or left side.  So we spent the $10 on a vent check instead of plumbing all the possibilities...  |

Check valves are a good start but ff you route the vent line out the top, around to the right and across the bottom to the left, what part is not on top above the fuel level in any rollover upset ? Even if you stand it on it's nose, with the line routed from front to back as it goes around it will work where a check valve won't. |

Yep, that's pretty much the way the line out of the check ball goes, except for the front to back thing, not expecting it to stand very long on the nose or tail... It's the belt and suspenders mindset that helps get you older |

'The belt is just to show off your buckle before "DUNLAP", but it is the suspenders that keep you pants up." We will let Sum report on my full race adaption. DUNLAP defined: When your belt line is bigger than your Acura and it "DUNLAPPED" over your big gold buckle anyway, suspenders are indicated. |

Thanks to all who replied. I'm going to use a combination of line routing, check valve, and end filter.
Thanks!
Jim.

Make sure your filter, vent lines etc. are big enough. you can run out of fuel pretty easily.

Richard is sho nuff right on  At higher flow rates of fuel use, the vent, filter and lines needs to supply air above the liquid level at an equal or greater capacity or it has the effect of changing the fuel delivery curve.  Regards to All, HB2  |
