Madison Motorsport Posted January 10, 2009 Share Posted January 10, 2009 The 7k error code is for a seized EXUP valve. The EXUP is located inside the belly pan under the engine. If you look at where the headers meet on the exhaust, after that towards the end can is a box with a lid on it, held in by two (or three, I can't remember) socket screws. These usually get siezed by the usual abuse of normal use so you will need to soak in WD40 for at least 48 hours before trying to remove them. I have an EXUP refurb guide if you want to PM me your e-mail address. As for the pipe issue, I would recommend buying a couple of metres of fuel hose and replacing the affected bits. You may also need to invest in a couple of small hose clamps if the ones that hold the hoses to the tank are missing (they are only small and usually get lost at some point).

steve m Posted January 10, 2009 Share Posted January 10, 2009 You are going to love the Exup,, if it ain`t been serviced on a regular basis it`s going to be a royal pain !! If you do as madison says and you are lucky enough to get all the bolts out ok, make sure you change them for all stainless items and when you replace them make sure you use plenty of Copper Slip...........

Madison Motorsport Posted January 12, 2009 Share Posted January 12, 2009 Sounds like your tank has either started to rot from the inside, or the gasket on the fuel tap wants replacing. Link to comment Share on other sites More sharing options...

Madison Motorsport Posted January 14, 2009 Share Posted January 14, 2009 I suppose it could always be perished carb mounting rubbers (the bits that hold the carbs on to the block). Link to comment Share on other sites More sharing options...
