mark i hope that isnt the only inline filter you have because those filters will let alot of debris still flow through. i had a fuel pressure regulator on mine and it was causing problems so i pullled it out and put one of those in for looks. there is a good filter out back near the tank. just figured you should know that those filters are crap.

Yeah... I'm fully aware those aftermarket glass filters are garbage. They'll catch the big stuff, but that's about it!
As of today, I have two fuel filters on the truck. I put the crappy aftermarket filter near the fuel cell, and an OEM style metal filter near the fuel pump.
Back to the proper procedure for setting the timing... I've searched this forum through and through, and I can find posts both for and against disconnecting the vacuum advance.
Which is the Mazda-approved method? I don't know. I guess I will go with the method that makes the truck run best, and keeps it from overheating.
