I need to remove the FPR and the bolts are extremely rusted on. Plus the bolt is slowing stripping and stripping. How can I get it off? Can I cut the screws somehow? Please help!

FPR? I'm drawing a blank what that is . . .

probably a fuel pressure regulator.

have you hit it with penetrating oil?

yeah, I've been using every bolt buster I can find. Still stuck like glue. I may just put tons of liquid wrench on it, let it sit overnight, and then see what I can do. But i'm having a hell of a time trying to unscrew it just cuz of its position and some mild stripping going on.

For some odd reason I can't picture where it is or what it looks like. Is it a nut or bolt you want to get off? How big is it? A pic would really help.

You are taking the right approach though. Let it soak and give it some time for the oil to really penetrate. Hit it a few more times with the spray too. Normally I'd say heat will help but not in this case, don't want to get flame anywhere near the fuel:eek:

I would also suggest verifying that you have a 6 sided box wrench. When the angles are awkward, a 12 sided version can round the corners quite easily.

Good luck!

We've had an off line conversation and it seems he's trying to get out a phillips screw that's rounded on the inside. I suggested an impact screwdriver or some vice grips if possible. I know sears has some bits that are made to dig in and get out stripped screws so those may work too. I've never used those but they sound like a good idea. There are always easy outs but on something as small as it sounds it may not be a good idea. That would be a last resourt. I've tried small easy outs and I've managed to brake one off in the process. Then you are really screwed (no pun intended)

Thanks for clarifying, Peaty. I have never removed the FPR, and can't picture the problem.

I have used screw extractors, however. If it comes to that, the best bet is to first use a center-punch to mark the point of contact. Then use a fine drill bit (sized smaller than the screw extractor) to make a few mm pilot. Then place the screw extrator in the drilled pilot hole and set (lightly) with a hammer. Lastly, gently connect to a drill and slowly remove the damaged screw out of the hole.

I learned this the hard way when I forgot "righty tighty" on a caliper guide. D'oh! The head of the aluminum screw snapped off like it was made out of butter.

if the screw isn't large enough to use a screw/bolt extractor on there are a couple of other things i can think of. in the past i've used a dremel or a cut off wheel to cut a groove in the head of the screw, and then used a flat blade screwdriver to remove the screw. there are also special pliers that are designed to grip the outside of a screw head, allowing you to turn the screw to back it out.

i've broken easy outs on bolts before, and i'd only reccomend those as a last resort.
