Does anyone have suggestions where I can get a reliable good quality electronic fuel cut off switch? Cheers Rich
You mean a fuel solenoid? Telecamit used to do a good one, unfortunately no longer available. They do exist, but they all look rather ropey Chinese jobs...
I use the valtek one listed by earlylatebay above....not had any problems with it and cheap as chips.
Where is the best location for one of these valves, I would have thought between tank and pump before any filter and outside of the engine cupboard but I noticed on one advert it said that on carbureted engines it should be between pump and carb. Don't quite understand why, would it present a restriction which might interfere with the pump action ?
I'd have hoped with your profile name you'd have known best.....let's not wait around for @puddleofpetrolPhil...
Mine's in the engine bay (so between pump and carb as directed). It's a green one like in the link above, been in there for 3 yrs now seems to work fine. I know some folks don't think it's a good idea to have anything that could leak in the engine cupboard, but tbh if it's easily visible you're potentially more likely to see / notice any leak - more than you would if it was somewhere underneath the bus? 02p etc.
Needs to be between tank and pump to stop fuel being gravity-fed into the engine compartment if the fuel hose bursts, which is the whole point of fitting the valve
One reason why they might suggest between pump and carburettor is that the fuel pump sucks hard and I used to have a problem where as the engine stopped the pump would end up sucking on the solenoid valve which dropped shut as the ignition turned off. And then it stayed sucked shut when I tried to start it next day as 12 volts did not pull hard enough.. Two solutions- I chose the hard one of driving it from a boost converter that winds it up to 26 volts for a moment as the ignition comes on.. or I could have used a diode and a capacitor to hold it open until the engine stops.. Mine came from a guy who fitted night heaters to trucks. He closed down shortly after I bought my solenoid. So it goes Tank, metal filter( Halfords) , solenoid , firewall, pump. Stops fires. As I discovered.
This is mine using electric fuel pump all mounted together on the plate sitting above the gearbox just after the tank outlet Before anyone says anything I have never had any problems using these filters..I do buy the more expensive ones locally and not off fleabay
