If I use the 1/4" from the pump to the carbs, is the engine going to starve, I can't see the 216 using more fuel than this. I realise though, the stock line is 5/16. But I like shiny stuff, and well, that's about it. Just general maintenance, and putting a better filter on.

Stock should work, but I definetely wouldn't undersize it. | | | | | Joined: Jul 2004 Posts: 5,708 'Bolter | | 'Bolter Joined: Jul 2004 Posts: 5,708 | YIKES...it does say 'carbs'.  While I still think 1/4" might work, I'm going to side with the Swingdaddy and say don't go smaller than stock size. It's my understanding that two carburetors does not equate to twice as much fuel, but actually almost the same amount, but better distributed on the intake. This is why it's important to reduce the venturi size on the dual install carburetors. They are now flowing at half the CFM each (of the engine), which means half the fuel each...does this sound correct!

He may have used 5/16", but never any bigger on any of his rides. I really doubt youd have any problems with 1/4" on a 216.

All of the gasoline has to pass through it. | | | | | Joined: Jun 2008 Posts: 1,388 Shop Shark | | Shop Shark Joined: Jun 2008 Posts: 1,388 | Ahh, that's true isn't it! It has to go through that tiny little hole. I think I'm break out the NeverDull. | | | | | Joined: Feb 2009 Posts: 26 Apprentice | | Apprentice Joined: Feb 2009 Posts: 26 | Not trying to steal this thread, but i have a similar question. Will 1/4" line starve my 454 w/4bbl carb? I want to use an old elec. fuel pump and thats what size the fittings are. Don't really want to use adapters.

It appears to be a great improvement. I also put in an inline filter using rubber fuel ine connectors that I hope will deal with the vibration as well.
