I need to put on a different lift pump system. I talked to a guy at a diesel performance shop, and be has a 24V like mine, and be was putting on a FASS HPFP, not the filters. He decided against the full FASS system, cause a friend of his said that he had gelling issues in the winter with his FASS.

Is the gelling problem because of the finer filters?

Is there a heater in the stock fuel filter housing?

What are your experiences with these systems?

I am also considering the Airdog system, if I won't experience gelling problems.

It does get pretty cold around here, and I don't park inside at all.

Thanks,

I would not say that a fass is the cause of fuel gelling, fuel gelling would be the fault of bad fuel/lack of additive.
I belive it is still possible to retain the stock filterhousing/fuel heater with the Airdog, I'm sure the venders will chime in. I just installed an Airdog..as per instruction I ditched the filter housing and went with 1/2 fuel line.

Gelling problem most likely due to he got rid of the fuel heater in his stock filter setup.

Yes there is a heater in the stock filter system... (Although, I'm unsure if your truck has it, I think it does)

Do you have a Block heater?

If I were you, I'd spend about $130.00 on a Walbro GFS-392 and get a bypass regulator for it (GDP sells one, also Summit has a few).
You could probably just tap it into your stock fuel system.
Do you have an in tank pump?


I get a kick out of all these guys putting 150 GPH pumps on their truck, and still have stock lines, or no need or plan for fueling mods down the road.

wildcat,

I do have a block heater and the in-tank pump. I would probably need a big line kit with a Draw-Straw wouldn't I??

I guess that would all depend on your planned modifications. What you have right now certainly doesn't call for it. If you use the Walbro GFS-392, You could just put it in your existing fuel line. Since you have the in tank pump, you would have to drop the tank, and pull the old Fuel Pump out, and replace it with an in tank fuel siphon hose. You would also want to disconnect the wiring to the old pump, use it to fire the coil of a relay, and run a new 20A fused wire to power the Walbro.

If you are worried about fuel gelling, use your block heater to keep things warm, you can also run an extension cord out to your truck and put one of those heavy duty work lights under it to generate heat.

I live in Az, so I really don't have to worry about Gelling unless I go up north hunting. So far, it hasn't been a problem.
I'm sure others will have better ideas on that.
