How close is too close to run fuel line next to headers (ceramic coated)? The fuel line is braided stainless? Is one inch too close at one point?

I think one inch is too close. I like to see 4 inches of clearance minimum.

Way too close. Remember, braided stainless still has rubber or plastic inside the braid. Hard line you might get away with at one inch, although you could still boil the fuel inside the line.

There is no way I would run ANY type of fuel line that close to a heat source like headers as the out come for even the smallest failure is deadly or at very least catistrophic.
Run the fuel line on the outside of the frame rail then into the engine compartment on top of the frame rail then accross to the fuel pump and up the front of the block securing it so that it cannot touch the headers.

I too would agree that an inch is way too close, especially if it is a hose rathyer than a hard line. I'd prefer to see the fuel line on the other side of the frame ir wheelwell sheetmetal. If you have to be that close, put a heat block between them AND use hardline through that area. Hardline will, at the least, just stop the engine with vapor rather than frying the rubber and letting the gas out to the nice hot manifold.

Thanks for the help. I have run a hardline along the inside side of the frame and transitioned to the top of the frame just before I get to the firewall. I was thinking about continuing along the top of the frame with my flex line and tucking in tight directly along that brace that heads toward the fuel pump, however that would mean getting very close to one of the header primaries. Instead, I will loop the flexline over the top control arm and drop down to the fuel pump. This will keep the fuel line well away from the header.
