Fuel Pump Fuse
Hate to have to ask such a simple question but...Replacing leaking water pump - '87 C4. Want to relieve fuel pressure but fuse box doesn't match only fuse diagram I have (Haynes). What fuse do I pull?

Just remember to not turn the ignition switch to the RUN position. Doing so will cause the fuel pump to run for 2-3 seconds and that will pressurize the line

That's another vote against the Haynes book! It's not much use for anything other than bird cage liner! The FSM (Factory Service/Shop Manual) is the book you need!
I don't have an '87, but isn't there a fuse labeled F.P.? Maybe on the bottom row?

Thanks to all for the responses. Yep, there's a fuse "FR" on the bottom right. "Fuel relay" perhaps? Also, thanks for the input on not needing to relieve pressure. Since I just got back from two weeks in Scotland and the last time I started it was before I left, I assume I don't even need to pull the fuse. Thanks again. Great forum.
