Anyone know the size of the OEM Fuel Pump Cover Screws for a 00 Civic? Mine are missing from previous owner and want to replace them with some black screws.

 

If you mean the ones that attaches the assembly into the firewall, those should be somewere 20mm length and the wrench to be used is a 10mm . Just changed mine yesterday.

You have 2 screws and nut. I have a 99 EX.

 

The four behind the front seats.

 

Don't know the size but ate a ecu screw and see if it fits. They look the same when I upgraded my fuel pump.
And be careful there screw into plastic.

 

Gosh I confused pump with the filter, thats why I mentioned the firewall. Sorry!

Havent play withh the pump yet thanksfuly.

 

probably 10mm X 1.5 get some metric stainless socket heads and paint them black, the bare steel socket heads will just immediately rust, the black oxide ones

 

I meant 5mm X 1.5 I was thinking wrench size

 

IIRC they're a #10 coarse thread screw, essentially a wood screw.

 

Are we talking about the cover under the rear seats?? Because those are a coarse thread, with a Philips #2 head. Honda parts diagram will usually give a clue to length and width.... or is it width and thread pitch
