I have heard that this is a very bad idea that has been proposed and tried many times in the past. The washer pumps will not last very long and will contaminate the fuel as the pump parts fail or disolve. The Slimline pumps are the best thing available but possibly the company has gone under or is under new ownership. There WAS a pump ovehhaul kit that consisted of new rollers and special large diameter thin wall tubing [it is a parastaltic pump]. However the pump kit is not available from Slimline, except posssibly from one company "down in Texas". Sorry but this was just a conversation at the field today with a very knowlegable fellow that owns many Slimeline pumps. He is high up in heli competition and this is the pump they mostly all use. After hearing this, I am thinking if I ever was going to get a Slimeline pump, now is the time. I own three of those [expelitive] yellow Sulivan electric pumps and they all leak, sometimes badly. There is a huge need for a good, affordable pump for glow fuels and [dare we hope ?] gasoline.
