Here is where I’m at I have installed a newly rebuilt engine (L29) in big green finally got the distributor set at 0° where it needed to be was having a slight fuel smell under the hood figured it was because the Distributor not being set correctly.
Ted who is helping me set a distributor said he also smelled a strong raw fuel smell under the hood when the truck is running never had this issue with the old engine.
I have checked the fuel lines and (new)fuel regulator coming up to the back of the intake And don’t see any fuel leakage when I got back home from dinner tonight it was dark I checked under the hood with a flashlight and what I think I see is where fuel is coming out between the platinum and the intake has anyone had this issue before?
My thoughts are I don’t have the plenum tighten down enough, in the past when I’ve taken it off and put it back on I just tightened it to where I thought it should but this time when I put it together I torque spec everything oil pan, Exhaust manifold, intake manifold and plantain to the torque specs.
The fuel smell is very strong under the hood and it’s only there while the truck is running or after you run the truck and you stop and you open the hood if it sets overnight the smell dissipates.
When I start the truck fuel pressure goes up to 55 psi when I turn the truck off and slowly drops down to about 30 psi if I let it set overnight with the fuel gauge on it the next morning it reads15 psi.
thanks in advance for any thoughts on this issue.
