Default Using truck coil packs with ls1 rail

It seems the snout of my fuel rail runs directly into one of my coil packs. Anyone know of a work around...aside from moving the coil pack?

You wouldn't happen to have a pic would you ? Might help with ideas . I was going to use spacers under the coil mounts to raise my coil packs up farther away from the valve covers for clearance with my headers , but I am not sure that will work in your case .

Gently bend the fuel rail to clear. Just be careful not to kink it. Put a screwdriver in the tube and go slowly. Heat will help, but this may not be an option for obvious reasons.

A little kink may be ok if you're not running a big HP engine. My 5.3 didn't care at all, but I ended up with a new rail that I bent more carefully, so its all smooth now.

Not that matters but is it ok to flip the fuel rail around? Will it affect how the pressure regulator works...more importantly I have a Weldon boost referenced regulator I want to use, so will it work with stock reg on the rail?

I bent it up and forward a bit. Did it by hand. Just barely clears.
