I have had my 87 spider quad for a few years now and it has been driving great. Just recently I have been replacing the fuel hoses from the fuel rail to injectors one at a time. The first time it was the line closest front of the car. I didn't think much of it and just replaced it. Drove the car a couple of miles and, next, the fuel hose closest to the firewall injector burst. I was now a little suspicious and replaced that fuel hose. Just today I let the car idle in my driveway for about 15-20 minutes and the fuel hose to the injector adjacent to the one closest to the firewall burst. I am going to the replace that fuel hose and the one other remaining old fuel hose, but I can't help but think that some other part (fuel pressure regulator?) has failed and that is why my fuel lines are bursting. Anyone have a similar experience?
