I am new to this forum and am looking for some assistance from people who know what they are talking about. I have a 78 280z and I can't get it to pass smog.

So I'm running with a suggestion that my '75 280Z is having engine problems because trash in the fuel tank is clogging the screen.

The symptoms I described were indentical to what was going on with is car - running well for some period of time and then suddenly loss of power, sputtering and finally stops running. Let the car sit a while and start it back up and all is well... sometimes. Over the weekend I drained the tank and yes there was some particles in the fuel which I strained into a gas can. Didn't really look like rust. So I dropped the tank and got a little surprise. On top of the tank there ap…

I need some help!!!! the fuel pump of my 280ZX was loosing pressure so i took it off, and replaced it with an homologated one, because i couldn't fine the original. The one that i found is the pump that works in the german cars like old BMWs and Mercedes, and it has a pressure of 95 psi, what i want to know is, is that pressure the right one for my injection system or maybe is it too much or too less??? can somebody help me??? does anybody know what is the right pressure??? the car is running fine but sometimes it smells like gas!!!
