Injector removal & wiring harness routing

[BFlat]

Is it easier to leave the FP Regulator attached to the rail when removing/installing injectors?
Also, ads for replacement wiring harnesses state that they are longer to make routing easier. Is that so they can be routed on top of the rail, or...?
Thanks

Get a Caspers replacement harness. No need to remove FPR.

If you have already purchased the long harness It can be a challenge to make it look good but I ran one for years and grew happy with how it looked down along the valve cover, but it gives you options.
With the new Holley harness i got I was a little disappointed with Caspers stock replacement, but after installing i really liked the tucked in fit with less clutter.
I would highly recommend Caspers stock replacement.
