Guest Anonymous Posted March 11, 2003 Share Posted March 11, 2003 I'm trying to get an intank pump out of my 85 200sx turbo, but the whimpy little phillips screws holding it in are so rusted tight that they would rather let their heads strip than budge. I've pretty much hosed one of them, and I've soaked them in wd40 for a while, but to no avail. I don't want to have to drop and drain the tank. Any suggestions?

Guest Your Car is Slow Posted March 11, 2003 Share Posted March 11, 2003 Penetrant....or an ezout :/ Quote Link to comment Share on other sites More sharing options...
Tim240z Posted March 11, 2003 Share Posted March 11, 2003 Enough room for a vice grip? Or maybe file the edges and use a small wrench? Tim Quote Link to comment Share on other sites More sharing options...
Jeff Posted March 11, 2003 Share Posted March 11, 2003 Kroil is the best penetrating oil that I have found. Soak them several times and even the most stubborn fastener will come loose. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted March 11, 2003 Share Posted March 11, 2003 I'll try some Kroil if I can find some. There's really not enough room for vice grips unless I drop the tank. The heads are too small for filing and wrenching. Hopefully the kroil will work. Know of any major chains that sell this stuff? Thanks for the tips. - Rob Quote Link to comment Share on other sites More sharing options...
Mudge Posted March 11, 2003 Share Posted March 11, 2003 I dont know what an intake pump is, unless its an smog device (air pump?). If you can get a small propane torch on it, they whup ass. I soaked my brake lines for days on end with penetrating oil, to no avail, with vice grips I just rounded them off and broke lines, when I finally got the torch I did the rear brake lines in mere minutes.

denny411 Posted March 11, 2003 Share Posted March 11, 2003 I think he`s trying to get the sending unit out of the fuel tank. I`m pretty sure a torch would NOT be a good idea. Quote Link to comment Share on other sites More sharing options...
Mudge Posted March 11, 2003 Share Posted March 11, 2003 Ok, if its a fuel pump or something in the tank, right-o! Even after totally emptying them people are wary of fumes, and frankly better safe than sorry. Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted March 12, 2003 Share Posted March 12, 2003 An impact screw driver is a handy tool for screws. Absolutely essential with a motorcycle. http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=37530 Penetrating oil, heat, hot wax all work to help loosen up the screws. Since it is near fuel can't you just drill out the screw head with a hand drill? Quote Link to comment Share on other sites More sharing options...
Guest DRK Posted March 12, 2003 Share Posted March 12, 2003 I second the motion made by Jim for an impact screwdriver. I had to buy one for a motorcycle I was working on a while back. It is a great tool, and there are many screws I have come across that I would not have gotten out otherwise. I think I paid around $25 for my Craftsman unit.

Mudge Posted March 12, 2003 Share Posted March 12, 2003 Since it is near fuel can't you just drill out the screw head with a hand drill? Most drills I know of make sparks, maybe a brushless motor wont? Quote Link to comment Share on other sites More sharing options...
383 240z Posted March 12, 2003 Share Posted March 12, 2003 I've had good luck with a small amount of valve lapping compound on the tip of the screwdriver. it provides a good grip between the blade and screwhead. That and the penetrating oil ( I use PB Blaster) should do the trick. Keith PS an air drill makes no sparks. Quote Link to comment Share on other sites More sharing options...
fl327 Posted March 12, 2003 Share Posted March 12, 2003 i like pb blaster too, i usually tap it in and let it sit for a day or so, and if its still tough i use a screwdriver and a hammer, havent had one resist that combo. Quote Link to comment Share on other sites More sharing options...
VRJoe Posted March 12, 2003 Share Posted March 12, 2003 Sears has a new style of bolt remover, it looks like a socket, try one of those if it comes small enough. I keep hearing good things about pb blaster. - Joe O Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted March 14, 2003 Share Posted March 14, 2003 Hey!....If you haven't blown yourself up from a previous suggestion then you will read this when I say that at this stage you will likely contaminate the tank to get the screw out without damaging the tank itself anyway. I would: See if there is such a thing as an air or electric powered impact tool just made for this sort of thing. Bike inpacters are great sometimes but if the screw head goes then you get nada anyway, besides, you have to hammer on the manulal impacters, this may damage the tank itself if not careful. If the impact required to break the screw loose is greater than the strength of the tank then..... Last chance: Drill it for an EZ-out (contaminates tank), then apply smaller size vice grip or perhaps the manual bike impacter (if it can be made to grip the EZ-out). Overall I guess this is a worst case situation because heat is dangerous to your health here.....LOL. Metal shaving residue? What dosen't hang in the bottom will be caught by the filter I suppose.

Kroil is the best stuff out there! Find it and have it in your garage at all times. Quote Link to comment Share on other sites More sharing options...
Trevor Posted March 14, 2003 Share Posted March 14, 2003 CUT slot across the screw head for a flat blade screwdriver. Use a hacksaw - not a power (dremel would be tempting) tool - sparks in the gas tank would not be good. Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted March 14, 2003 Share Posted March 14, 2003 I guess I should have been more clear, a hand POWERED drill. You know, the old turn crank type. But, from your post, it sounds like you don't have the clearance for any of this stuff. Can't get nothin past this group. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted March 15, 2003 Share Posted March 15, 2003 OK, I just remembered there is such a thing as a 90 degree 36" flex cable that will chuck a drill for that. Just need a motor to drive it (after you manage to borrow one). I'd loan you mine except I don't have one. Quote Link to comment Share on other sites More sharing options...
j260z Posted April 3, 2003 Share Posted April 3, 2003 something that works most of the time for me is firstly penetrating oil, then insert your screwdriver and give it a good whack with a hammer. i found it's usually just enough to break it free. no sparks...no explosion.
