Check valve needed...

[GNSteve]

I'm running a JC alky kit. I have a problem with my alky being siphoned back into the motor via vacuum. I e-mailed Jay who said he no longer sells the kit and referred me to Dan at OGS. I e-mailed Dan and haven't received a reply yet. If Dan doesn't come through, does anyone know where I can find a check valve?
The valve in question comes after the pump and before the braided line going to the jet on the up-pipe. It's made out of brass, and is threaded on the inlet and outlet sides.
Can anyone help here? The engine will drain my tank dry in a day or two. It doesn't help that I'm running a .045" jet, either.
Chad, any info here? TIA!

I have the JC kit that I bought through OGS, a couple of months after I bought the kit, Dan sent me the check valve as a retrofit. Keep emailing him, I had better luck calling but that was a couple of years ago. This is a brass check valve that requires spring pressure be overcome by the pump to flow into the motor (prevents siphoning by vacuum), and a positive seal to prevent boost from backflowing into the alky tank.

Company called Circle E makes them all brass for lots of applications, would prolly work for alky.

Don't know what fittings you have but the one I have here has 1/8" NPT female threads in it so you could adapt it easily to AN braided line fittings.

My part is 232B-1BP rated at 3000psi. burst.

They are in Corona, CA

If all else fails might be an alternative.

Thanks guys...

Mike,

Sounds exactly like what I'm looking for. Mine came with one, although it stopped working a while back. Don't know why it's only been giving problems recently.
Anyhow, I guess I'll keep e-mailing Dan until I get some sort of response. Calling is another option, but the time difference is killer for me. (means I have to get up *real* early)
salvageV6, thanks for the info. I'll definetly keep that in mind in case things don't work out with OGS. Thanks to all that replied! Any other ideas?

check valves

I can get you the brass check valves. They use a spring loaded steel ball as a seal, and the spring cap can be driven in farther to increase it's vacuum resistance if needed. $12.

Steve,

Sent you an e-mail about the check valve. Thanks.

They must have changed the pump since I had my kit. I had one of the last kits Jay made himself. The pump I had you could not suck air/fluid through. Apparently the new one you can hense why you need the valve.
