How I did fuel filter change on '88 305TBI

(I read both Hanes and Chiltons, neither was complete in explanations and steps)

Hi! Good news, I changed my fuel filter . Here's what I did:

1. Jackstanded car , front and back, driver's side
2. Loosened gas cap, let it vent
3. Took out fuel pump fuses, 2 (FP)
4. Started motor, let it ran 2-3 minutes (inj.#1 running on oil pressure mecanism, fail-safe...)
5. Pulled out fuse in black sleeve facing battery and pinned clearly near fender
6. Killed motor instantly
7. Fuel pressure was then releived to the fullest
8. Took adjustable wrench (wescot) and 16 mm wrench key
9. Took 10 mm socket, socket driver and 3'' extension
10. Took 2 small pans (plastic)
11. Put on latex gloves, cotton head cap and goggles
12. Went under
13. Wescot on fixed nut welded to fuel filter (FF)
14. Wrench key on moveable nut (MN) centered on fuel line (O-Rings?? sorry , not a pro...)
15. Loosened MN, motor side, by counter forcing wescot and wrench key (pretty easy, no rust, lucky...)
16. Minimal fuel spill
17. Same loosening action on MN , tank side
18. Again , minimal fuel spill, it even diminished after about 20 seconds!
19. Loosened small bolt , 10mm, on metal clamp that holds the filter in place (easy, again no rust, lucky....)
20. Made quick moves to swap new one in proper flow direction , like indicated on Fram filter...
21. Old one : AC Delco part # GF-481. Maybe the original FF, who knows...?!
22. Tightened reasonably MN (O-rings ?) in place, nice and clean
23. Smiled inside while wiping underside
24. Tightened bolt on metal clamp
25. Job done
26. Pulled myself up from under and did indian victory dance with neighbor...
27. Went for a ride, now pulls better, quicker and smoother...no kidding

Am very grateful for everybody's help and counsel, thanks
