The Fuel Flaot You Have Now Is Comtiable WIth B13 Meters....
You Need To Get That RPM Type B13 Meter......EFi Type....!
It Will Have VSS Speedo As Well As RPM Meter...Make EVerything Work 1st...CEL/Petrol/Temp And Everything Work....You Need To Wire The Damn Thing All Again.....That's One Hectic Job...I Have Done It And Know How It Feels....!
Then Come Toward RPM In End.....If You Can Fiddle With Pulse Type And COnvert It For B13 RPM..Thats Great....Else You Need To Swap The RPM Meter With N-16 Type...For That U Need To De-Assemble Your B13 Meter And Get RPM From N-16 Type And Fit Into This....
Just Don't Go For Whole Meter Swap As I Don't Think It Will Fit Into That Tight Dash Place And You Need To Do A Whole Lot Of Work......Possibly Some ALters Which Will Make It UGLY JOB
