When you crimp your fuel return line then the vehicle can be rev up what can cause this?
When you crimp the fuel return line, it creates a restriction in the fuel flow, which can lead to increased fuel pressure in the fuel rail. This higher pressure can temporarily allow the engine to rev up because more fuel is available for combustion. However, this is not a sustainable solution, as it can cause fuel starvation and damage the fuel system or engine due to excessive pressure over time. It's crucial to address the underlying issue rather than relying on crimping the return line.

1988 Chevy Celebrity 2.8 liter fuel injection your car does not stay started inless you remove the fuel return line what is your problem?
There is a pressure regulator on the fuel rail, it regulates the fuel pressure to about 45 lbs/sq.in. Excess gasoline is sent back to the fuel tank via that return line. If the return line is somehow blocked or plugged up then the excess fuel might cause flooding thus the engine would die. I assume that when you loosen the return line it leaks fuel out?
