Other than to not cross the exhaust, Is there any reason to maintain the fuel line routing around the front of the engine to the mech fuel pump location, if you are installing electric pumps and removing the mechanical pump and blocking it off?

No. Years ago I routed my all steel fuel line along the outside of the driver's side frame and moved the selector valve, a filter and an electric fuel pump outside the frame. My line goes up to the area of the brake combination valve and then on an angle up to the rear if the engine. It is connected to my TBi system with braided stainless steel over Teflon lines.

Sean,
Due to possible vapor lock, I'd would think to keep the line located in the coolest and least vulnerable route. Which is what I think GM did.

I preach to get the lines out to the outside of the frame and mount the
tank selector outside where the air in slow traffic an be much a 50
degrees cooler .
Some have had good results without doing this, but when you have covered
over almost 2 million miles under different conditions in the last 35 years
in these coaches, I have experienced various phenomena that some of you
have yet to face.
Be sure to replace the selector switch if not done in last 4 years

I recall Steve Ferguson had routed his stainless steel gas line between the
left valve cover and the intake manifold. It was raised above the intake
manifold by an inch or so. There was a photo of it but I can't bring up
any of his postings.
