A couple of questions for the experts

[gnel]

I´m going to drop my fuel tank soon and was wondering if I have to buy a new sock filter or can I just clean up the old one? Any suggestions that will make this task easier are welcome.I am also going to replace the lift pump. Rock Auto lists 4 manufactures from cheapest to most expensive they are Airtex,Carter,Delphi x 2 and ACdelco. Wich one do you all think is best? Will the new lift pump be a straight swap or do I need a kit for that? Thanks to all g

The sock can be cleaned . Get a fuel pump for a 93. It is slightly higher pressure and volume. It seems most things electrical on these trucks is best replaced with oem-AC Delco.

stock LPs are generally speaking crap. I went thru 3-4 in about a 3 year period. Even a couple of ACs. My current one is 2yrs old (got lucky).

For what it is worth, I'm running a Walbro LP and it's doing fine. Picked it up from PMDCable.com along with a WIX prefilter set up. Works great. Got a little air in the system when doing the swap over but it cleared up right away. Hardest part was figuring out how to set it all up but I made a simple bracket, fitted it up and it has been running fine for the past couple of months.

On edit: I'm no expert though but I did sleep in my truck on the way home this past weekend....

can't remember but it's whatever the local parts store had. I bought a couple of walbros for when it dies and for my other trucks. Not going to change it till it dies tho

I would eliminate the sock all together and put an external filter in before the LP. A cheapo clear in line one, or a nice spin on filter setup.

I prefer the sock myself even though it is 70 micron rated it does offer some protection,

GM put it there for a reason which I theorize it also serves as a suction "foot" when fuel is sloshing in the tank pickup tray, vs single point of suction with tube alone and I believe aids in gel clog resistance in cold weather, if gelled fuel is present it is strained on the sock yet some is allowed to flow past the checkvalve in the sock.

As far as it clogging often you have to get some really bad stuff to clog it up over time, the times mine clogged I know when it got clogged after using some waste fuel from a test cell that has old aircraft filter cellulose media entrained in the fuel that was caught in my Racor pre lift pump filter. I like to run 3 tier protection the sock for the "big" stuff, my 10 micron racor pre lift, and my 5 micron pre IP OEM filter, but that's me.

If the sock was easier to get to I would agree but since it's such a pain to get to I'd eliminate it and mod the pickup if needed.

I just dropped my tank. It isnt too bad. I feed a hose into the tank, put it in a 5 gallon fuel tank, turn on my shop vac and create some suction. Pulls the fuel right out. Disconnect the guage sender in front of the tank on the top of the cross beam above your drive shaft. Then disconnect the fuel fill and return line. I dropped the tank onto a milk crate, got to the fuel lines. then eased it to the floor. Swapped in the new one. reversed the process. To prime, mine will run the LP if you put it in reverse and then crank the key (with the fuel filter cracked).

Insert curse words and bleeding, and you are about done. Nothing is as easy as it reads. especially the fuel lines. what a pain.

Thanks for all the replys. Should be an interesting weekend.

x2. Remember replaced sending units MAY NOT have the diesel flap. Check your sock, it should have a built in 'flapper', this is what TD was referring to in time of GELLING.

I had mine ice up and cause stall (and above mentioned curse words). Turned out I had the gasoline sock on my Diesel Sending unit from NAPAss.

I ended up removing that flap and going RACOR spin on filter that is accessable.
