I currently have a RDS 91 gal aux tank and currently use it as the gravity feed system. However I HATE the gravity feed, sometimes it takes 2 days to fill up my tank!!! I want to add a fuel pump and 12V shutoff valve so I can control everything from in the truck while driving. Problem is the RDS drain valve is a 3/8 female connection and I cannot find any 12V 3/8 shut off vales! does anyone know were I can find any? or if anyone has a similar setup, what have you used?

Thanks!

 

what about summitt racing? they have alot of different items there. I found what I was looking for when i did my ccv mod.

 

I looked, didn't see anything. There is this place

12 Volt Fuel Valves but the only one they make in a 3/8 is an odd shape and i do not think it will sit flat since the drain hole is very very close the touching the floor already.

 

well i see this one is not so easy. there are a lot of combo's out there with a quick google search but they are all big.

 

No its not... I will try searching more forums, because I know I am not the only one who did this.

 

This looks promising:

2-Way Zero Pressure Solenoid Valve [2W16010N] | DudaDiesel Biodiesel Supplies

More possibilities here:

Process Valves, Water Solenoid Valve, Steam Valve, Diaphragm valve

 

Thank you! the first one looks good. But is it 12V? I actually just decided to check on amazon, and I actually came up with this one I think with a 3/8" male to male coupling it should work

 

12VDC is one of the options you can select in the drop down box on the first one. I saw the Amazon one but it lookid hinky, in particular I believe it had a rather small orifice, 4mm vs. the 16mm orifice on the first one I linked.

 

EKTMS,
I have a 60 gal RDS gravity feed, and it runs all the time, thus keeping my tank topped off. Are you just opening the feed valve when your main tank is near empty? I don't have much problem keeping my main tank full, except when towing heavy, it will use faster than the fill--but it catches up overnight. Do you have the RDS gravity fill check valve installed?

Yeah, I only open it when it gets to about half way, doesn't seem like the right thing to do, and when towing it drops to quick even if I leave it open hours before. I do have the RDS gravity check valve. I hate it and it will work much better with a fuel pump and electric shut off valve so I have full control.

 

My odd idea has been to put a 200 gal or so tank in the trailer with a pump, and plumb it up to the truck with appropriate breakaway connectors and electrical connection. Flip aux switch as needed to transfer fuel up from the trailer and keep on truckin'...

 

LOL! wow! that would be pretty crazy!
