Area Representative Paul Richards Posted October 11, 2010 Area Representative Share Posted October 11, 2010 Following some adjustments, I'd like to check my fuel pressure. Firstly - Am I correct in thinking it should be around 3 bar on my 1.8k Supersport? Secondly - Anyone in the North West got a suitable gauge they could lend me?

geko Posted October 16, 2010 Share Posted October 16, 2010 Hi, sorry can only provide for the Duratec engines: ~4.5 bar. Regards Gerhard Caterham CSR 225 MAZDA MX-5, Mk2, 1840ccm Edited by - geko on 16 Oct 2010 15:16:30 Link to comment Share on other sites More sharing options...
oilyhands Posted October 16, 2010 Share Posted October 16, 2010 Some 1.8K supersports have a fuel rail with an adjustable FPR, these are set to 4 bar. If you have the standard fuel rail with the stock rover regulator then it is 3 bar. The adjustable FPR is aluminium and has two nuts on the top for adjustment. Remember that the FPR is referenced against manifold pressure so when the engine is under no load and manifold vacuum is high the indicated fuel pressure will be lower than 3 bar since the gauge is referenced against atmospheric pressure.
