Nothing wrong with changing the filter first, just in case it's blocked and that solves the problem. But I would plan on having to replace the pump as well. The regulator is part of the pump assembly, it's all in the tank.

Basically it involves cutting out the metal above the tank then adding an access plate to cover the hole like what w bodies have. I wouldn't do it on a collectible low miles high value car but my m6 car in my sig already has it done and any of my others would get the same , once its done fuel pump access is easy.

Honestly, even in this case I would and will if I ever have to. It's not something that would ever be visible, nor is it harmful to chassis integrity. Some cars have these access panels from the factory as you mentioned. IMO, doing this mod is just correcting a factory oversight (sort of like drilling access holes to remove the rivets for power window motor replacement.) The factory put cut provisions in the rear carpet for access to the shocks, and they should have done something for the pump as well.

Dont drop the tank, just cut the top, do a search there a google video. I done it and it saved me big time, bc now I have to change the sending unit also. If you get a fuel pump just get the racetronix with the hotwire kit also.
do the trap door, seriously youll forget its there and its no big deal at all.
your call though.

Cut it out last night, figured i would drop a pic for anyone trying to do this on there 99+ TA. Still waiting for my racetronix 255l/hr to come, Just woundering sinse this pump has a little more juice than the stock, would upgrading my fuel rails show a noticable difference?

your stock fuel rails will not be a restriction on any setup with a 255 pump
