After looking to order new pump I have two options: with or without vapor return line. How do I know if I need a vapor return pump or not?
Just look at the pump, if it has one line in and one line out, then you don't have the vapor return...and I don't think the 350 2bbl had it anyway, unless maybe A/C equipped cars.
There will be 2 lines back to the tank for vapor return, a total of 3 lines.
X2 400 engines get vapor return
used clear plastic gas filters without issue for years
