I'd like to know what you used for the petcock bung. I just ordered one of those glass filters and I'm thinking about fabing up my own tank.

Thanks Allen

hepcat - if you ordered the same as I have, the NAPA one - it's got a built in petcock that works really well (lil T-handle on the back/top of the filter)... if you mean the fitting to the tank, it's all stuff ya can find at your local plumbing/hardware store

That bike is SWEEEEET... definitely a looker. Missed this thread somehow, and found it while googling for the glass bowl fuel filter.
Cheers

I'm looking to do something similar on my bike, temporarily nick named "The Rojo Mofo"...But the frame of the bike necessitates that this style tank ends up sitting lower than the engine. Not so good for fuel delivery.

Anyone have any ideas on fuel pumps or is there enough vacuum from the engine to just suck it up?

Pete

There's no draw from the carby to suck fuel into the float bowl - only from the float bowl through the jet via the venturi effect, so yer lookin at some kinda fuel pump... which I'm not entirely sure anyone has done bfore w/these engines. Maybe? Probably? *shrug* I've not seen one anyway...

Still, if I hadta do it I'd consider something like a vacuum powered diaphragm pump, common on many small engines.

You'd need to tap off the crankcase or intake manifold for a vacuum fitting, but that'd be a heck of a lot easier than tryin' to keep power going to an electric pump... and while I'm sure they're out there - I've not seen a 'letric one that lil.

Here's some more vacuum fuel pumps... but I dunno the rep of the company: http://www.scootsusa.com/fuel-valve-...les-p-109.html

Those are some great links,

Yea thats what i was thinkin too, the electric pumps are ganna be a hassle. If I could rig one of these vacuum pumps up thatd be a lot better. Thanks. If I decide to go this route I'll def post some pics and such to show how it goes.

Can you weld a tank like this this with an arc welder? (with the sticks I mean)
Or do you need MIG?
