Need fuel line routing info plz.

On my 77 Wagoneer, it has a 360, 4 barrel, when I got it, it had the mechanical pump still on the engine, but disconnected, and a electric fuel pump just sitting in the engine compartment. Here's the deal, it has what looks like a return line fuel filter setup. I'm not sure if I hooked it up right or not. I took the electric pump off, put a new mechanical pump on and it's hooked up the 3/8th line from the tank, to the pump, goes into the fuel filter, than the other end of the filter one side goes to the carb, and the other to the return line to the tank. Is this correct???

Here is how the lines where hooked up when I got the vehicle.



So that's how I hooked it back up. But I don't think it's right.

factory style fuel filter

When I bought my J10 years ago the factory fuel filter had been replaced with a aftermarket type without the return line (small return line was tucked away down at the frame). My Edelbrock 4bbl carb was getting hot and vaporizing the fuel. I installed the proper filter with return (just as you have labeled) and the carb has run cool for years.

Your diagram is correct. Make sure that the return is oriented so it is in 12:00 position

Ok, cool. Thanks. I did find out my tank has a lot of sediment in it, and it killed the fuel pump in a couple hrs..

I'm thinking I'll pull the tank, and get it cleaned, and install a new pump again.

Before running it, add a see through filter before the pump! The extra work you save in the future will be your own! (I did that rather than drop the tank and packed a spare filter)
