labrat Posted June 30, 2004 Share Posted June 30, 2004 Well, my Z has been sitting for a couple of years with only 1/2 tank of gas, so I got some rust in the tank. My fuel filter is clogging up after about 1/2 tank and causing the fuel pressure to drop, and causing the motor to run lean (TBI). My question is this: What is the best way to loosen rust that is in the tank after I drop it? I was planning on buying a pound or so of BB's and pouring them into the tank, then shaking it till my arms fell off. Then give it to my friend to shake till his fall off. Then rinse and repeat. That's worked for me in the past with motorcycle gas tanks. I really want to stay away from the gas tank coatings, have heard bad things about them from other members. Mostly flaking after a while and clogging intake tubes. I know I have to drop the tank to clean the sock on the intake tube, and rinse out the rust that is in it now. it will also give me a chance to relocate my fuel pump, as the rubber boot on my half shaft is rubbing the fuel line out of the pump. As always, all suggestions are greatly appreciated! Bill Quote Link to comment Share on other sites More sharing options...
280Zone Posted June 30, 2004 Share Posted June 30, 2004 pull everything off of the tank and take it to your local radiator shop. They will clean and boil it out for about $60. Quote Link to comment Share on other sites More sharing options...
SpeedRacer Posted June 30, 2004 Share Posted June 30, 2004 Take it out and drop it off at your local Gas Tank RenU dealer http://www.gastankrenu.com/welcome.htm They do an awesome job and it comes with a lifetime nationwide warranty!

Tim240z Posted June 30, 2004 Share Posted June 30, 2004 Don't use your arms to shake the tank....strap it to a dune buggy and go offroading for a day Tim Quote Link to comment Share on other sites More sharing options...
labrat Posted July 1, 2004 Author Share Posted July 1, 2004 Good tip, Tim. My buddy has a jeep, and it has been raining here for like 40 days and 40 nights.... Problem is, I've dropped almost 3500 bux in this car this year getting it running with the 350, and my budget is now shot. 60 bux is outta my league! Gotta do this the hard way, (that is, with no money). I'm sure I can, but the work is gonna suck... Bill Quote Link to comment Share on other sites More sharing options...
Tim240z Posted July 1, 2004 Share Posted July 1, 2004 $60 is worth it's weight in gold versus contant fuel system problems..... Quote Link to comment Share on other sites More sharing options...
labrat Posted July 5, 2004 Author Share Posted July 5, 2004 WOOT! I lucked out! I pulled the tank today to check it out, and it wasn't rusty at all! Just had some sediment from years of bad gas, I guess. I pulled it out, rinsed it with water, and it is now sparkling clean. No more clogged fuel filter, and no more running lean. YAY!
