Fuel Filter Fix
Fuel Filter Fix
I ran into the same fuel filter leak in my 64 330GT. I tried copper but it wasn't soft enough to seal without putting more tights on it than I cared to. My solution was to braze a washer under the head of the bolt. The ID of the washer should be 3/16 inch larger than the bolt. Center the washer on the bolt and braze away. This creates a recess around the shank of the bolt that is just the perfect place to put an O ring. In my car, you have to remove the entire filter assembley to put in a new seal and both copper and aluminum are one time use deals. Since I did the O ring thing, I've replaced the filter several times now without removing the entire housing and no leaks. tim

Copper Washer
If your copper washer is used, thus compressed and leaky you may anneal it, which will make it like new again. Just hang the washer on the tip of a coat hanger and put the torch to it till it turns glowing red hot, then dip it in water. :)
The original washer is aluminum and I believe it is softer than the annealed copper. As I said, I didn't want to tighten the bolt enough to get the copper to seal. I think I may have tried using copper at that time but it's been a long time. I used the oversized washer to containg the O ring as they tend to squish out of the way. Another option I didn't know of at the time was something called a Stat-O-Seal. It has an O ring contained by a washer. If they have one in the correct size, it could be a great problem saver. I think Earls has them. I may also have mentioned before, take the cork gasket out of the Fispa fuel filter/sediment bowls in the engine compartment and replace them with a National 225 O ring. Your filters housings will stay nice and dry. tim
