Csosz74 Posted March 10, 2010 Share Posted March 10, 2010 Hi everyone, 1990 LS400 the fuel pressure regulator leaks. Is it easy to change? Is it dangerous to drive around until I get the part? I have average tech skill, used to do plumbing:-) Also, can something else cause the leak other than the bad regulator? p.e. bad fuel pump, or whatever. Otherwise the car runs fine... Thanks A Quote Link to comment Share on other sites More sharing options...
curiousB Posted March 10, 2010 Share Posted March 10, 2010 Well if fuel is dripping onto a hot engine eventually leaking down to the exhaust manifold or an errant ignition spark due to a failing plug wire nearby. Then yes it is dangerous. A little fire under the hood would likely not be welcome. I wouldn't leave this too long. Quote Link to comment Share on other sites More sharing options...

Thanks, actually I just came from the mechanic, the problem was the fuel damper, not the regulator. He replaced the seal on the top and now it's fine. And yes, he said it was dangerous.
