Ideas please, fuel filter bracket bolt stuck and stripped
 
Edit: Problem is now fixed

So I was trying to change my fuel filter today and got everything all depressurized and took of one of the lines from the fuel filter. I saw that the bolt was all rusty so I sprayed it with lube and waited for a bit. I tried using an 8mm socket but I could feel it was loose so I used a 5/16 (slightly smaller). Then I totally stripped it. [mad] I need to get the bracket off so I can change the filter, and my first thought was just to grind it off. However, grinding makes sparks and I'm not sure that would be a prudent course of action.

Here is what it looks like:

I believe that bolt is 7mm.

ick... and it's recessed, so not easy to get to!
Damn midwest salted roads, too!

As long as there's no fuel leaking, and if you haven't popped the clamps off/removed the filter, there will LIKELY be no concern, as there is no fuel to ignite.

Maybe a few whacks with a center punch to the middle of the bolt head to create a divot, then drill into it (long bit required, obviously) then an easy-out in a socket/extension and very carefully twist it out.

Or, increase the size of the drill bits gradually until the bold head spins off, then pop the bracket off the nub.
Or (I've never bought one) a stepped drill bit - it has a gradually increasing diameter, which MIGHT just cure it, once you can get it to 'bite' into the bolt head. And, if it FITS next to the filter/hose bits.

May require a trip to the tool store, but anything you buy will be handy to have for the NEXT fiasco!

Good luck!

It is actually a 5/16 (~8mm).

That would make me extremely nervous. If a single spark ignites any fuel (hope there aren't any vapors in the air): He will not only kill himself, but make a mess for anyone who finds what's left.

The first thing that comes to my mind is: Can you use an EZ out to drill out the existing screw?
If not: Could you possibly sacrifice the entire metal clamp, and simply cut it with something (pair of bolt cutters perhaps)?

Those are my only ideas. The actual screw isn't very deep. It's just enough to keep the filter from bouncing around too much.
Maybe after you install it back, or replace it: You should make a custom-made plate to keep the road's salt from hitting it and rusting it again. [|)]

I guessed I never messed with that bolt but instead loosened the fuel hose clamp on the filter end going to the tank then loosened the 7mm bolt on the filter bracket that holds the filter, slid the filter out of the bracket to replace the filter.

macdiesel 03-30-2013 02:17 PM

Yeah if you could loosen the filter enough to slide out. Shouldnt have to mess with bolt

a_2000_se 03-30-2013 02:25 PM

Or - if the 7mm is rusted too, use a short piece of a hack saw blade to split the filter bracket - VERY CAREFULLY. Then zip tie the bracket after replacing the filter.

If you drill it out use reverse drills.

Where you using six point sockets? That's all I use unless forced otherwise.

macdiesel 03-30-2013 04:21 PM

Maybe hammer on a smaller socket?

sailor 03-30-2013 04:52 PM

Yeah, hammer on a smaller six point B4 trying anything else, you MIGHT get Lucky!
