Re: Airtex E8902 Debacle
Inside the frame rail just in front of the left rear wheel is accessible to the fuel line, well protected, and low enough that any functioning electric pump will pull the fuel out of the tank, even if it has run out and there is air in the line. I know this from experience (see phooto).
The Mr. Gasket 42S is low pressure (3.5 psi), and allows the mechanical pump to pull fuel through it when the electric pump is off. It has worked fine for five years, but I carry a spare anyway.
Put a service loop in the hose both in front and behind the pump, for ease of installation and replacement. You can use two small vice grips to pinch off the flexible fuel line loops when changing the pump or the filter, thereby avoiding fuel running down your arm, or having to install valves, which introduce their own failure points.
