How often do you change your fuel filter?

The problem isn't the pressurization... The fuel filter is large for the size of car and holds a good cup of gasoline and the gasline feeding it runs down from the tank and holds even more gas. It will pour out on you as you disconnect the hoses.

There are things you can do to minimize it. I used kelly clamps & hemostats to clamp the hoses... but there is still a gas spill from the filter being full.

It's a fun job to do by candle light. ::Flame::

YMMV

EFI cars all have a bleeder valve on the fuel rail that can allow pressure out quite easily. You may get fuel on you this way. If you let the car sit for a couple hours before disconnecting the fuel lines, most of the reserve pressure will bleed down.

I always just un-screw the gas cap about 10 minutes before messing with the fuel lines and that helps a lot.

I'm not sure if it's easily accessible on a Miata, but I have always pulled the fuel pump fuse or the fuel pump power connector and let the car die from fuel starvation.

Either way the filter still has gas in it. I dont think it can get much less messy.

Ooooo! And it stiiiings!

Texas has some of the worst gas in the country from what I hear. In school I was told that premium gas had additives and detergents in it for the top side. This last week in training I learned that high test gas does in fact have a higher octane rating, but also encourages carbon build up on the top side and doesn't possess the detergents that I thought it did. Guess it's back to a periodic bottle of Techron in the tank and the occasional BG top-side flush-out.
