Anyone know a source for small Check Valve on Fuel Supply Line right after Water Seperator on MK2 Cars?

Why for?

...so when you drain the water seperator,
even the one on the filter,
it doesn't syphen back and draw in air.

Most people just get rid of the water seperator,... but the check valve does help keep the fuel system primed.

Only I'd move it up into the engine bay so I didn't have to lay on my back to mess with it.

The dealer wanted about $22 for it last time I checked.
You might find a cheaper check valve at NAPA, if you do let us know.

I just looked in the ETKA and there are 2 check valves listed for vehicles with water traps, part no. is 3A0 201 542 in the return line and it lists for $11.50 and either 165 201 542 and it lists for $13.95. Funny thing, the check valves and water separator aren't and the water separator isn't even listed in the parts list.

They also list the OUT banjo, part no. 068 130 157, and it lists for $9.00.
