Fuel Tank Sock Part Number

[BrentN]

Going to drop my tank this weekend and give it a thorough cleaning. Had a batch of bad fuel...gunked up a couple of filters, so my sock is likely in as bad of shape.

Does anyone have a part number and source for an aftermarket fuel tank Sock? Called GM and they dont carry (or so they claim), but were happy to sell me a $400 sending unit with it included. Napa didnt either.

Thanks in advance.

You would maybe be better off to remove the sock and add a pre LP filter, they can be found cheap at NAPA and are easy to install, no more clogged socks... while you have the tank down you might want to install the new style P/U & sending unit, no more gauge bounce and much more accurate tank readings.... I don't know if I am allowed to post a link to the part here, I don't think any of the vendors here sell it, PM me if you want the link..

You can clean the sock very easy, if it's not coming apart..

Recurring theme as of late. Aftermarket sender (with sock) and hair pulling headaches ensue.

Aftermarket parts are often good, but more often inferior as has been the case here. Ask Casey (Arveetek) and I think there was one other that followed shortly after.

Just took a call yesterday from a guy with a 93 and new aftermarket sender. Truck went like 200 miles then shut off with filter full of air.

John, do you know what brand it was, I have had very good results with the one I installed, hope it doesn't croke on me now....

[BrentN]

Thanks all. I will pull it down and give it a good soaking and a wash as well as the tank and put it back together. If it is trashed I will order a new sending unit.

Yeah, it took me several months to figure out that it was the aftermarket "sock" that was squeezing down and shutting off fuel flow. I reinstalled the OEM "sock" and all has been good since.

I don't know if you can even find an OEM "sock" by itself. Like the original poster, the only option I found was a GM sending unit assembly with an insane price tag.

If you really do have a clogged OEM "sock", you should be able to take it off and clean it well with brake cleaner or some other solvent, and be back in good shape.

Thanks Casey. Didnt get to the cleaning this weekend. Maybe this week. Always something coming up.

Brent, if you have time, could you post as to "how" you went about dropping the tank and how it went for you? It doesn't look to be all that hard, but I sure wouldn't mind reading about your experience.

This isn't meant to sound cocky but:

Drain or run tank to near empty, support tank (across broad surface like a slab of plywood and a floor jack), disconnect filler tube, disconnect feed/return lines, remove straps, lower tank.

Remove tank sender/pickup unit by removing locking ring and lift out of tank.

Install in reverse order.

The rest is just spinning wrenches.

Of course, you could just remove the bed if you find that an easier route.

Like 6 bolts, the filler tube and some electrical connectors and it will lift free.

Well, it will with a lift or 4 strong friends....

Thanks. I don't need to do it right now, but I've been under there for other things and looked at it in regards to "what if". I thought it was pretty straight forward - but was mainly curious if I was over looking anything. From what you wrote, it appears it's as straight forward as I was thinking.

I've got a Burb... it might take more than 4 friends to lift the "bed"! :D

The Burb should be even easier. Roll back carpet and insulation above the tank. If there isn't an access hatch above the tank, make one. Some model years had one, some didn't. I've never nailed down the years/models that originally had one. If it were me, I'd also install a low-point drain while messing with it.

Do you mean an access hatch big enough to remove the tank? Wouldn't that affect the structural integrity of the floor?

Or, are you referring to one just big enough to get to the sending unit? I'm not sure why I didn't think of that - I'm a boater and the cockpit floors will have a "deck plate" to access the sender.

"Low point drain"? Do you mean in the rear cargo floor?

[DmaxMaverick]

An access hatch for only the sender. You could make one large enough for the entire tank, I suppose. Properly done, it wouldn't compromise the structural integrity.

A low point drain for the tank. It would make contamination clean-up a lot easier. There was a time nearly all vehicle fuel tanks had these.

If you need a drain for the cargo area, you have bigger problems!

[DennisG01]

Good idea... Again!

"drain"... Yeah, you had me scratching my head on that one!
