Esprit V8 fuel pressure question


GrahamS

Recommended Posts

I have a question regarding V8 fuel pressure and would appreciate your thoughts. I didn't start the car, just turned the ignition on until the pump stopped then I measured the fuel pressure.

After the 1st time I could see pressure dropping visibly at about ~5psi/second 

After 2 more KOEO until pump stops:

Pressure was 58psi initially 

Pressure Drops to:

50psi in 5 min

49psi in 10 min

48psi after 15 min

Is this drop enough to indicate a leaky injector?

 Thanks, Graham.

not necessarily a leaky injector.  But could be a sign that the fuel pumps are failing, or that the hose above the fuel pump is not sealing.  A few people have had cracks in the hose above the fuel pump, which will result in a large loss of pressure and running issues, but a smaller leak at the hose to fuel pump connection could cause the pressure to drop quickly.  The pumps should hold pressure for quite a while.
