Leaky floats - fuel shutoff

[Waiex191]

I ended up putting in a solenoid shutoff.  Here is the installation.


I bought the same one as Reloader.

Here is the shut off I am using even though I do not have any leakage issues:

I still have to put on hose clamps and do the wiring.  Here it is with the sidecover on.  Note the fuse tap in place.  I'll design and print a new cover for the fuse box later.


The one thing I don't like about it is the orifice size is only 0.156".  Everything else is 1/4" in the system.  I think I'll chuck a length of fuel line back in the tail in case this fails on the road.

If I have any issues with it, I'll look for another fuel pump that has a real shutoff.

Let us know how it works. Question: Is the valve rated for continuous duty?

I noticed this term when I looked up the specs on the normally closed solenoid valves.
Meaning that certain solenoids draw power to open the flow and after a set amount of open time, the coils are subject to overheating if they are used (energized) for more than 8 hours continuously.
The only solenoids they rate for continuous duty are the motorized ball valve design.

Here's some wording I found from US Solid Valves:

PLEASE NOTE: This valve is NOT a continuous duty valve and should NOT be in continuous use for more than 8 hours in a single cycle; to do so will shorten the life of the valve and may cause the core of the valve to burn out. If you need a continuous duty valve for your project please search for our U.S. SOLID Motorized Ball Valves.


"....Suitable for use with hot or cold water, gas, air, very low viscosity fluids (< 20 cst), oils and hydrocarbons, e.g., gasoline, kerosene, or diesel fuel. Valve is not intended to be energized continuously for more than 8 hours. This can lead to burnout of the coil, and malfunctioning of the valve. In cases where this is necessary, it is recommended user install a computer fan to keep valve cool...."

Good question, I'm not sure on the duty cycle.  It is 1.2A, so about 14W.  Here is the company page:

I will probably work a different solution in the long run.  I'd like to motorize my plastic Briggs and Stratton valve.
