How long do you give the gauge when doing a leak down test on the fuel pressure?

 

you shouldnt loose more than 10 psi in 10 seconds after the fuel pump shuts off. and if it does drop then stabilizes (lets say 20 psi) and stays there for 10 minutes or longer thats ok because the fuel pressure has a predertimined psi that it closes and seals. if it drops to zero within a few minutes i would say you have a leak somewhere

*the 20 psi was just a random numberfor an example, it does not have to staibilize at 20*

 

I lost a pound or two with-in a min or two. It took about 10-15 min to drop to 30 psi. so I guess I'm good to go.

 

yep, i dont see any problems there
