The top hard line coming from the tank is the return hose. The cigar hose gets connected to it.

The lower hard line is the supply line and the primary filter hose gets connected to it.

Don't know the size of the clear hose offhand.

Here, the engine dies in five seconds and doesn't want to restart.

So, presuming that you don't have bad fuel from a recent fill, my thoughts would tend toward the fuel pump.

Remove the line from the pump to the secondary filter and put it in a container. Crank the engine for 15 seconds and see how much fuel is delivered. I don't remember the exact spec for the pump, but, you must see at least two ounces of fuel........otherwise the pump has failed.

brian is a smart guy he will get through you through this

It was nasty and I went to the autozoneclubdiscountzparts and asked for the prefilter and I got a new one that looked pretty much like the dirty one, but clean ya know?

Paper looking filter, I guess.

When unsure of your driving range, see if your odometer indicates that you've gone past 400 miles. Usually the cars get around 400 miles at 25MPG but I think the SD has a larger fuel tank. Either way, I wouldn't always trust a new part that's been replaced and would keep an eye for potential problems. Glad to hear you got that sorted out, and nothing worse (stalling in the middle of the freeway) happened.

I have seen those at AutoZoo. They used to stock the proper plastic mesh prefilter. What they stock now has a paper element. Definitely no good for diesel use. The least bit of water seems to seal the pores of the paper. Car stops running. I wouldn't use those unless you don't mind changing it every week. Around here, Poop Boys still stocks a decent prefilter.
