Fuel sytem rebuild...

I replaced my mechanical fuel pump a couple years ago. Truck started having problems. I'm 90% sure the fuel pump died again. This time I'm up for a bigger project and some upgrades.

I'm going to replace my dual tanks and mechanical fuel pump with a single replacement poly tank and electric fuel pump. I just want to simplify everything.

The problem I'm having is figuring out what to put back in. I'm slowly finding out that the previous owner didn't do a very good job putting things back together.

Example: when I went to replace the fuel pump last time, I says, "gimme an '85 chevy fuel pump." Well, long story short, I had an older fuel pump without the return line. I'm not even sure the dual tanks work -- or were installed properly. Just a big headache...

So I want to make sure I'm going about this right -- I just want a single saddle tank mounted on the PASSENGER side. (don't want to have to make a million bends when I make the new fuel line). I think I need GM Part #6429439 -- but this says it's for drivers side only -- is that because it's assuming I have dual tanks? Or do I need a different sending unit?

Then I run a rubber line off the sending unit into a filter on the frame rail.

Then I run another rubber line from the filter to the electric pump (keeping it all as close to the tank as possible).

Then one last rubber line from electric pump to some brand new nicopp line.

Nicopp line run as close to the carb (edelbrock 1406) as I can get. Might have to re use the old fuel line that runs up behind the water pump and some more rubber line.

Should I add one last filter before I go into the carb?

Do I need a return line?
