87 fuel lines to TBI
« on: August 19, 2014, 06:29:47 PM »
87 350 TBI and my question is....I have two lines going to the back of the TBI  does it matter which side they go on behind the TBI?  Before I disconnected i took pictures but the pictures were deleted and the lines look like they could go on either side. I can see the lines stacked on the frame then turn to flex then back to SS thanks in advance.

The fuel lines are not the same size and will not interchange.  The 3/8" (10 mm) fuel supply line connects to the driver side fuel nut at the back of the TBI body.  The 5/16" (8 mm) return line connects to the passenger side fuel nut.

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!
