Re: 1987 Fuel Sender Conversion for LSx Swap
So your tank fumes just vent underneath your truck? How's that work in closed spaces?

Re: 1987 Fuel Sender Conversion for LSx Swap
I just converted my 85 this weekend.
The OEM vent is 5/16. It is now the return line. The OEM return line off the mechanical pump is 1/4. It is now the vent line. The 87 sending units use a 1/4 vent line so it's meant to be! My vent line t's both my tanks in back and goes to the charcoal cannister up front. Working great. |

Re: 1987 Fuel Sender Conversion for LSx Swap
I just used 1987 blazer tank and fuel pump then swapped out the pump its self with a acdelco ep381 from rock auto. The sender already had threaded ends which then I had to add adapter fittings to connect to AN fittings and lines. My truck was a return style fuel system. Everything seems to work great
