central - east central Minnesota - | oilmaster - 1/10/2014 16:57 When a fuel filter is gelling and the engine is still running, it is getting less lube components to the fuel system at the ppm level. When the fuel becomes warm enough it will dissolve the build up in the filter, thus giving more lube properties to the fuel. My concern is linear lubrication of the fuel to the fuel components----final answer.............. So, does a gelled filter stay gelled (clogged) when it warms up------no. It has to get pretty warm to dissolve the wax in a filter . . . . 20-30°F temps will not be warm enough. I'm guessing here, but I'll say the temps would need to be in the 50°F for sustained days before the wax/gell would dissolve. The warmer the better . . . .
If I know the filter was gelled, I'd change it - I wouldn't run it in the spring or summer - filters are cheap, compared to a fuel system (old or new). |
