How long a fuel line will a 40efi fuel pump pull through?
I'm looking to relocate my fuel tanks to the front of the boat, but before I run 20ft of line, how well do these 40 efi ful pumps pull through a 3/8 fuel line? I'll post a pic of how I plan to run it, but itll be roughly 20ft of total line with an abrupt 9" rise from tank to gunnels then 14ft run to the motor.
Pics to follow.

Length is not as much an issue as diameter - smaller is better - use 1/4" line instead....

Re: How long a fuel line will a 40efi fuel pump pull through
I'll never run smaller fuel line than the size of the fuel pump inlet and outlet. My carb is 5/16, fuel pump is 5/16, 1/4 has to run faster through the line. Same concept as plumbing your house. The feed line shouldn't be smaller than the lines in your house. You're actually forcing the fuel pump to work harder.

Re: How long a fuel line will a 40efi fuel pump pull through
Agree with Russ.
Buzz, my 40 is modded, tank up front and 5/16" line all the way. Probably 20-25' total with no issues. I'd say 16-21' feet between pump and tank.

Put a bulb, then the lift pump will do its job.
Hell the pulse pumps pull 25' no problem

Re: How long a fuel line will a 40efi fuel pump pull through
Well I'm going to try it, thanks all for the feedback I wont be doing anything until after this weekend. Walleye tournament on the Bay of Quinte in Ontario.
I will be the only mudmotor on the water - guaranteed.
But I also make a point of never messing with something that is currently working before needing to use the boat. The line is run, all I need to do it hook it up and try it out.

Re: How long a fuel line will a 40efi fuel pump pull through
5/16 would be the best for your fuel line,3/8 will also work .gl

Re: How long a fuel line will a 40efi fuel pump pull through
So I gave it the ol college try this past week with seemingly no issues. I think I'll add a bulb to the line though....

Re: How long a fuel line will a 40efi fuel pump pull through
I always put a bulb to make it easier to prime, and if that lift pump fails you can keep fuel in the fuel pump module with the bulb.
