Im putting together my replacement engine which is a 92 3.0 i4
my old engine is an 84 3.0 i4

The 92 didnt come with a fuel pump so I moved the pump from the 84 to the 92 and it fit but the fuel line doesnt look like its right, or long enough.
What im wondering is, IS THIS ONE OF THOSE ENGINES WITH THE UPSIDE DOWN FUEL PUMP?
Thats the only thing I can think of that makes this makes sense. If you look, if it was upside down, the metal fuel line seems like it would fit right up, the right place.

Do I need a fuel pump that goes upside down? If not I need a recommendation of a CHEAP electric pump and way to run a pressure switch off the oil line or something.

Id like to use the mechanical as it seems simpler, but it looks like i either need to buy a pump that goes upside down, or a different fuel line. or just run a generic fuel line from the output on the pump to the carb!?

To recap:
Engine is a 92. Fuel line is CORRECT FOR THAT MOTOR it came with it
Fuel pump is from my older 84

Thanks

You can use steel brake line tubing to make a new line. Must be double-flared connections. Not hard to do

I'm not sure but I don't think you can use the early 84 fuel pump on the 92 block, there is different pump levers.

Yeah its difficult to know. Everyone selling pumps never list the compatible years. The position of the fuel line sure makes me think it's one o those upside ones but which one to buy???? Heck if I know

Wow! Thank you!
Still makes the fuel line curious.
That diagram shows a normal way up pump which I'm not sure would work with it as you can see from the pictures. It wouldn't reach
