[Vwdiesel] Fuel gelling

[travis gottschalk]

When I re-powered my 81 rabbit car with an AAZ engine I also put a TDI filter on there with the thermo T on it and a hand pumping bulb all up front. Took some creative routing but it makes the fuel filter change and prime nice and no gelling since installed. The truck is still original but I have the parts to convert. I did have it gel on my once last winter but was able to thaw it out and dump even more anti gel to it. I think it had summer fuel still (town driving doesn't drain them very fast). Reason for my changing to a thermo T is even if the engine gets warm the fuel from the tank is likely cold and can still gel up the filter. But with warmer fuel from the injector return it can keep the filter above the cloud point once the car is warm. Don't know if the return fuel is warm enough but like I said it hasn't gelled in 2 winters with -35 dF and the return fuel has to be warmer then the outside temps. Also helps to have a Frost heater that some may have on there TDI's. I found those stupid block heaters didn't do hardly a thing and the frost heater gets the engine hot enough to burn your hand. If you leave the defrost on it will even start to defrost the windows in the car (vent open and valve open heat rises up enough to defrost with car off but only on my rabbit, not the 04 Golf). Any for any interested it mounts on easy. I put it on the battery bolt for the holding bracket and then it ties into your water piping.
