Posted: Sun Oct 28, 2018 12:52 pm Post subject: Automatic Fuel Line Shut-Off Solenoid Valve and Circuit |
|
|
My Dell 36's are sometimes leaking gas through overnight and the engine will be hydro locked with gas the next morning, one time it filled the crankcase with gas. This problem started about a year ago and I got it cleared up by changing a float but the problem has returned.
The CB-Performance 3 psi Rotary Electric fuel pump does not shut-off the gas from the tank when stopped so I have an Idea here to solve the problem.
Cheap $10 Solenoid Valve from eBay:
Current Limit circuit to keep the valve from overheating during driving.
Prototype:

Installed it finally, and it works!
Also rewired the fuel pump and all to run directly off the battery.
Updated Schematic:

Are you using a doghouse shroud? Any fitment issues with the manifolds/ carbs? _________________ "Albatross"! |

Yes it's the 1971 year with the DogHouse based 1600 DP and yes when I put the IDF manifolds on I had to do some grinding on the manifolds however longer intake manifold studs would eliminate that. They kind of force fit into the Head tins I did grind the IDF intake manifolds down some, also I drilled and tapped the Left Manifold for a Vac Line for the Brakes.
It's hard to change spark plugs in on cylinder #1 and #3 the longer type 4 spark plug receptacle may help. It's important to make sure the 8mm nuts that fasten the intake manifolds down aren't so big they are in the way of the sparkplug socket wrench, also a skinny sparkplug socket wrench helps. I like the Steel 10mm 12 point 8mm nuts best to secure the manifolds.
In a VW Bus there is plenty of room for whatever carbs you may want to use however on my bus I have all the wiring in the way of changing the #1 plug. I need to do that differently if I ever pull the engine.

The 74mm X 88mm Engine is still running perfectly.
Made my own Turn Signal Relay: Running Stock Turn Lamps etc LED Indicators though. Works Great!
This is my own design feel free to use it!
Prototype 2:
A Trench Mosfet is gated at 19 Volts to work as a solid state relay between +12-14 VDC and the Turn and Emergency Flasher Lamps to ground.
