Re: 1987 Fuel Sender Conversion for LSx Swap

My question is, do you really need to convert the return line into a high pressure line?
I converted mine to -6 AN for the simple reason that I was reusing some existing -6 AN lines for my fuel system. I am not sure what the actual pressure is in the return line (but should not be over 60psi), but on MY return style rails, I could only find the adapter for a -6 AN and it is just simple to change over the sending unit to -6AN fitting.

Most push lock hose and fittings are rated to at least 200psi and that could be a simple hose to make up with -6 JIC fittings (same as -6 AN fittings) that don't even use hose clamps. Having the -6 AN male to 5/16" tube fitting on the sending unit is just extra safety against a hose and clamp leaking.
