I am working on my dual tank system and would like to know what I can use besides a Pollack. I want to have my fuel pump and filters downstream off the valves as follows:

One 3 way for supply with 1/2" npt
One 3 way for return with 3/8" npt

I would like to have them wired to switch at the same time. This way I have diesel from the factory tank to and from the engine one way and Bio blend switched the other way. Any part numbers or suggestions are appreciated. I have emailed three companies and no replies.

Scotty,

The above is the best option I've seen yet - here I thought no one had any until I looked at the above link.

I think you've seen my set-up for my aux tank. Through my searches, I've found a tonne of pumps and valves with 1/4" ports, very few in 3/8", and next to nothing in 1/2". The 1/2" I did find, didn't work out of the box, in addition to being too big for my application.

I ended up with a pump from Dash and a valve from Princess Auto of all places (hydraulic section) - just a 2 way though to fill my OEM tank. 1/4" ports on the valve and 3/8" on the pump if I'm not mistaken.

IIRC, the only place I didn't try is Mopac Performance..............Good luck!!

I wonder if pneumatic valves will work with fuel?
I know some work with hydraulic fluid.
Get surplus ones here dirt cheap http://www.poweraire.com/3way-valves...7_379_394.html

Heres one site I found...

Now if I can find a place that will reply or is close to me, I might get this done.
Will look into the Pneumatic Valves too.

Thanks

frybrid and others sell 3 port solenoid valves for around 80$ each with fittings. hydroforce I think. They are also used for hydraulic applications.
Frybrid also offers a high flow version which I recommend for the intake side.
