Allen Bolts on Fuel Filter Mount
Is there a trick to removing the two allen screws that hold the vacuum line and upper A/C hose to the top of the fuel filter mount. It looks like these two screws also hold the top of the fuel filter mount to the support from the block.
I've had the heads soaking in PB Blaster and tried them on a hot and cold engine. Should I start beating the upper mount or use a torch or what? I need to remove one of the allens but don't want to strip it. Thanks, Willson 85 300CD |

Drill it out
The last time I had to remove those one of them would not budge and I ended up drilling the head off. I think I used a 3/8" drill bit if I remember correctly and drilled in to the head until it popped off. The shank came right out afterwards. Luckily I had some more bolts from an old engine kicking around to replace it with. Use anti-sieze both on the threads and under the head when installing it.

Fdanielson, so once you drilled the head off you removed the upper portion of filter mount and used pliers or something to continue un-screwing the remaining bit of bolt? I've never had to torture a bolt or screw on my car but I'll start with these two if thats what it takes. Once i heat it and pound it and finish by stripping the head tomorrow with the allen key, I'll end up drilling it out like you suggested. Thanks for your help fd.

I was trying to remove a Fuel Filter Housing at the Junk Yard and one of those Allen Bolts snapped My Allen Socket in 2.
Since I was at the Junk Yard and did not have all of My Tools I took out the big Punch I had with Me and put that over the Head of the Bolt and hit the Punch with a Hammer. That loosened it. A better way is to get a Punch that has a strait end OD the fits down inside of the Allen Screw and beat on the Punch with a Hammer. That way it does not deform the Allen Head. Beating on the Head of stuck Blot was a common way to loosen a Bolt at the Shipyard where I used to work. It works better when the Bolt is tightened on something Aluminum as beating on the Blot Head can compress the Aluminum under the Blot Head. It is also to better to have a heavy Hammer and a slow swing or simply let the weight of the Hammer fall on the Punch if it is a really heavy Hammer.

I got em
Thanks for the help fdanielson and Diesel911. I ended up getting a drift and beating them with a hammer, then used a 6mm allen socket on my ratchet wrench and they came out with about 40 ft lbs, way more than i could get with just the allen key.
Thanks again, Willson 85 300CD |
