Fuel tank change over solenoid

Right thinking momentarily out side the box.....

How about a T joint in the fuel line then on each tank have a fuel cut off solenoid.

You should be able to pick these up cheap as chips realatively speaking from the like of LPG conversion suppliers.

Then you can switch off one tank, both tanks (security!) or have them both switched on if you like (Balance the load a little?).

There will be other answers but I like to keep it simple...at least if one breaks then you can still use the other too.

There was a place advertising all sorts of fuel switches and valves in the back of one of the landrover mags (LRE in about july i noticed it i think). i cant remember their name right now, but will try and look later.

Words of wisdom from the bloke who fitted a 4.2 Jag engine into a Series Land Rover.

On or around Sat, 6 Dec 2003 22:51:33 +0000 (UTC), "CampinGazz" enlightened us thusly:

you could fit several solenoid valves instead, and a changeover switch.

the LPG types have solenoid-operated valves, which may or may not suit.

Have you thought of using two 3-port solenoids, slaved together, one switching the "feed" and the other the "return"? OK, it's not as elegant as a single valve, but it might be easier to find.

Gazz, Dont forget that not any old valve will do (with rubber popet valves/seats) Your using diesel so you will have to ensure that the valve medium will have to have nitrile or butyle (one or the other?????) rubber seats so that the diesel wont eat it!

Aye, thought about that a little bit, but not enough, most fuel tank change over solenoids seem to be aimed at diesels.. just the wrong voltage for me,

if i was in america i'd have no problems getting one, as fitting 2, 3 or even more tanks to diesel pickups is common, (heck most pickups there come with twin tanks from the factory.. i guess 5mpg has something to do with that :)

i like the idea about a couple of 3 port solenoids, so i can switch both tanks off for security, only thing i would need to be sure to get a constiant feed to the solenoids when the engine is cranking.. i've heard too many stories about people running the first tank dry, switching over to the the second tank, doing some work on the fuel system or some other reason to loose the prime in the fuel lines, then being unable to re-start the engine as the solenoid disengages when the starter is cranking, thus switching over to tank one for pick up.

One idea i have is to use the rear tank for greasle, and use that in the summer months, using a turbo timer to keep the engine running for a few minutes when i turn the key off, and have the valve switch back to diesel while this is happening and flushing the lines of the cooking oil, so i'll be able to start with no problems the next day when i forget to turn back to diesel before shutting down for the night.
