elmscroft Posted June 13, 2015 Share Posted June 13, 2015 Hi All, Just returned after sitting on M5 for two hours. With some tools and engine cover removed, looks like the Fuel pressure regulator gasket has failed. Up against a bit as due to tow caravan to France on Wednesday. Replaced Fuel Pressure regulator (FPR), Gasket and O rings, 500miles ago. FPR was advertised as a Bosch part, put when arrived, didn't appear to be which, seller did admit. If the FPR was to fail, would it cause gasket/O rings to fail? ie over pressure. On trying to re-start engine, M&S green lights were flashing, but not before we stopped. Could this be another issue? Time scale for parts is my main concern. Any input welcome. Discovery 2001, TD5 Auto, 60,000 miles. Thanks Quote Link to comment Share on other sites More sharing options...
elmscroft Posted June 14, 2015 Author Share Posted June 14, 2015 Hi All, Update, having thought about it overnight, thought bolts may have been loose, but checked and stripped today, bolts were still at correct torque, so now thinking, perhaps the Fuel pressure regulator has failed. Would it come out of there at such a pressure? reluctant to put hand in direct line of spray. With regard to the M&S lights, could it be gearbox has faulted, as when I lost power, it would of meant the truck, may have thought it was being towed? only guessing. Any Ideas?

Les Henson Posted June 14, 2015 Share Posted June 14, 2015 If it's leaking fuel, then it's faulty part and should still be under guarantee. Les. Quote Link to comment Share on other sites More sharing options...
elmscroft Posted June 15, 2015 Author Share Posted June 15, 2015 Thanks Les, just difficult to see where it is exactly coming from, can get a proper Bosch regulator by mid-day, so will run with that. Just amazed at the pressure and how quickly the tank emptied. Thanks for your input. Quote Link to comment Share on other sites More sharing options...
