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
I used plastic for years also, but was advised by my mechanic once to replace it with metal.....BTW, I had 'mental issues" with the plastic one once also...when hot, and car running...you could se no gas in it...seemed like it vaporized before going thru...I kept looking at it and saying, "theres no gas going thru, how can the engine be kept running"? lol...
