I searched and couldn't find the answer to this....I know the top banjo bolt on the fuel filter is a 19mm. Is the bottom a 19mm as well?

I can't even see the bottom bolt, which makes this a bit difficult...

Also, what size is the nut on the fuel filter that you put a wrench on to counter with? And is it the same size on the bottom?
 
There isn't a fuse that I know of. When I changed my fuel filter I didn't unplug the pump or anything, you won't lose much gas, it probably wouldn't hardly amount to anything.
 
Sooo after a few minutes of searching for it, its the MPI fuse.....so why are you going to say "wow" like I'm a dumbass?
 
Well I just unplugged the fuel pump in the trunk anyways. No big man.

But anyways, I don't know what the fuss is about the fuel pump. For some reason the 14mm flare nut wrench I had did NOT fit. Maybe I got a defective tool or something. But I used a regular 14mm wrench and it came right off. I sprayed PB Blaster on it the bolt/nut and let it soak and then again maybe 5 minutes later and let it soak. Came off so easy. Wrench didn't slip or anything.

Saw a great performance gain after the filter change...even though the old filter didn't seem that dirty. No brown gas or anything.

Could of been clogged.

That's what I was thinking. Clogged but didn't have any brown gas or anything. Was clear, and when I ran water through it, everything was clear. I say it was clogged and with the new filter, it can flow freely. Because man, does it haul ass now!

O hell yeah, clean fuel, air, oil, and good spark works wonder.
