Just finished putting in a fuel shutoff valve wired thru a relay. Works great. Also installed a starter inhibit relay for theft protection...just want to slow em down some.... |
jeff,
Where did you install the valve itself and how? Was it somewhere under the tank, in the engine bay or did you run the fuel line in to the cabin and install the valve there? I really don't want to bring the fuel line into the cabin...
Not finding a whole lot of room to install the valve anywhere under the tank (I'm eyeing the angled floor panel, just forward of the starter and over the heating tube.) _________________ Michael P.

Sorry, didn't have the camera in the house when I posted. Here are a couple pictures of the spot I put it. I just made a simple bracket (didn't get a pic) that bolts to the top of the valve. There wasn't any threaded mounting holes in the valve , so I used the nut that holds the magenet to the top of the valve.

Didn't think to use that top nut; brilliant, thanks!
I'll be getting mine done in a week or so (ran out of fuel line and had gotten 1/4" barbs by mistake ). I've got the 155 filter as part of the set up so its a bit heavier, but thinking a bracket like that will still work fine. I'm also thinking to put it on the starter side to reduce the exposed un-controlled fuel line run and proximity to power.
PS: fuel line clamps are your friends _________________ Michael P.

I ran the power to the coil on mine. I have clamps, just didn't have enough when I put it together to test.
The black line is late model OEM VW high preasure line, not generic fuel line. _________________ Pres. Rivercity VW Club www.rcvwclub.org

Completed my install and added photos to the gallery, search under "Fuel Solenoid Valve installation".
Works great!
Location is in the passenger rear wheel well, forward of the fuel tank on the floor metal. I had holes there already, so used them. Could have been new holes into the frame:
The valve, filter and bracket. The hose barbs weren't on yet. Secured the valve to the bracket using the valve's magnet nut per Teeroy's method. The bracket is a bent Stanley galvanized 3" angle. I'll probably replace it with a stainless one when I get around to it if I see excessive corrosion on this one going forward. The filter is screen and magnet, upstream of the valve. Both valve and filter are the stainless steel version of the AFC121 & AFC155:
Back-up manual valve using a reserve valve. I crimped the taller reserve intake tube to assure an "on/off" only operation. Installed a new copper filter in the tank for good measure. I installed the valve "backwards" so that the off was a simple pull, and so that the fuel line was heading toward the new valve.
The wiring was via a relay, installed in the engine bay. Power from battery to relay, control from ignition coil to relay. Used a Hella fused relay for simplicity. Mounted it in the engine bay to keep it sheltered from weather and worst case in a fire if I don't kill the power, the fire will soon enough by destroying the fuse or the relay itself.
Final install of the valve in location.

Based on a PM request, I figured I'd come back to this with a report on how it's working.
The system works fine in general, I've not had any running fuel flow issues.
I (unfortunately, but thankfully!) can't confirm it works as designed in case of fire.
One drawback is that it works *very* well to keep fuel out of the line past the valve. Great for fire prevention, not so great for a bus that sits long enough for the fuel in the post-valve line to evaporate.
I have to let the bus sit for a few minutes with the ignition on before it will fire up. If I had my druthers, I'd use a metal fuel line out of the tank to the valve and have the valve as close to the engine as possible outside the bay rather than what I've done which is to have it as close as possible to the tank to minimize potential for fuel flow in a fire.
But generally glad it's there! _________________ Michael P.
