After 4 years and 50K miles I've developed a leak along the seam between the solenoid and the valve portions of my Pollack 3 port. Causing a small vacuum leak.

Any one have one they're not using? Maybe moved up to a stouter valve? MikeGoodman59@aol.com

may want to look at this wvo valve




We have been running road tests on this aluminum bodied, 3-port WVO/SVO 12-volt fuel tank selector valve (also available in 24-volt) with easily-replaceable Viton seals. It has 12-mm ports with 1/2 inch NPT threads, a maximum operating temperature of 212° F, it is a bubble-tight valve (which means it is not going to leak like some of the other valves used for WVO) and it even has a small red light that tells you when you have switched to WVO! We have run this valve in VWs, Mercedes, and larger pickup trucks with good results.
For those who are interested, email me for a flowchart of the valves’ performance.
Other details you may want to know:
Max operating pressure: 1 MPa (10 bar) = 145 psi
