I have an 88 Formula, and I can SEE the Filter, I was wondering if it's possible to change it without having to drop the tank...

Since it is an inline filter that is bolted on, I don't see why not. I just unscrewed the lines and screwed the new one on my 87 when I replaced it. The hardest part was the opening the clamps that held it in place and making sure the flow was in the correct direction.

Since the fuel pump is in the tank, and the only exit is at the top of the tank, I don't see why much, if any, would leak out of the line when you disconnect it.

Rumor,
If you're worried about excess fuel dripping from the filter when you crack the line, Just run the engine and pull the fuel pump fuse out til the engine quits from lack of fuel. Then it should be bone dry when you remove the filter.

Well, it won't be BONE dry, but you'll only get around a cup or so of fuel from the lines. I use a metal bowl under the filter to catch the gas.

As soon as you pull the fuse the engine will quit because the fuel pressure will go to zero, however, fuel will still remain in the line, and it will run out when you pull the filter. There won't be much though, maybe half a cup plus or minus. Make sure there aren't any sources of spark, and if you want, you can let the fuel drain into a clean container and you can use it in your lawnmower. Here's a picture of the filter FWIW:

As you can see, easy to get to. Spray some PB Blaster on the threads and bracket screw beforehand to help ease the process, and be sure to only use the proper flarenut wrench to keep from rounding the fittings.

I did my fuel filter without PB Blaster or a catch basin. Not enough gas came out to be a problem.

Just make sure you use 2 wrenches, the way you're supposed to....

I didn't mean it would take a weekend to do it, just that I'd prefer to not do it some night after I came home from work...I want to swap out the front shocks and paint some of the underbody with POR-15 too, so I'd rather take it to my buddy's shop, put it up on the lift, and whack away at it for a few hours...

I don't think you have to worry about it AKA. It'll be a sinch once your motor is out!

Besides, you live in Canada, so what you have to be worried about is how bably the lines have siezed.

Lot's of good advise here but you may find that the steel line nuts sometimes freeze to the steel fuel line dues to rusting. PB blaster sometimes helps but I've replaced fuel filters where the whole line turned as you turn ther nut. If this happens, I just remove the line with the nut and work on it on the bench or just replace it.
As for the fuel hazard; yes it exisits. With the engine off, there is residual pressure in the fuel lines. When you loosen the fuel line nuts to the fuel filter so that you can remove them, it is possible for fuel to shoot out under pressure. My neighbor Bruce was badly burned when gas hit his hot shop light so mistakes can happen. Changing the fuel filter with the engine cold and with no shop lights (or electrical devices) in the vicinity should minimize the risk.
