Fuel filters?

I put a king-sized EFI filter at the back, in 1999, and no other filter. I have never changed it in 125,000 miles. My car goes 93 in the 1/8; you be the judge.
From the HO pump it's all steel to the dual-feed, no regulator,no return, no filter, Just a short jumper to make jet changes a lil easier.
