Fuel pump

[RGilliam]

How far will a 20hp or a 16hp vanguard pull from a fuel tank?

 

[scottwash]

As long as it says running. Lol

I have seen a rash of issues with the pulse-pumps used by all the mfr's..
Briggs, Kohler, Honda,.. they all use the black plasic fuel pump,
or the aluminum Mikuni vers.
Just to complicate things, the Vanguards have a "mystery-quirk" where one in 10 won't hardly operate a pulse pump at all.
..very strange ! .. but I will get to the bottom of that.

So, I'll say this..
Lifting the fuel more than 2 ft is questionable, but with 3/8" line, 10 feet away is no big deeal.

If you have to lift 2 ft or more, just go to an electric fuel pump, and be done with it.

What brand and model of electric fuel pump?

Will this need a return line back to the tank?

Where can one buy one on short notice?

Thanks.

Most any auto part store carries them. I ran them on my Kohlers due to the ethonal problems here.

 

[Tony Shelton]

Autozone has them. Fixes all those problems.

something like those? how do they hook up?

 

[offdutyfireman]

Similiar. Lookfor 2 to 3 psi. I hooked mine to the keyswitch so they only came on when the key was own. To much psi and they flood the carb.

 

[Christopher]

Would you install this between the fuel tank and the filter?

Do you need a line back to the fuel tank so the carb does not flood?

Thanks.

 

[Sirocco Jerry]

Chris, install it between the filter and the carb.
..the filter protects the pump.
As insurance.. you can add a pressure regulator, but I've had good luck without.

..for wiring..
on a Briggs v-twin, connect it to the white wire dangling from your engine over the starter ..
it is "switched B+"

 

[RGilliam]

how about on a 20hp honda? i bought one today. 2-3PSI i think it is

 

[Sirocco Jerry]

on the Honda v-twins..
it looks like the yellow wire that goes to the "Fuel-Cut solenoid" is your B+ wire,
and the other.. run to B- on the battery.

I got the fuel pump, it has a inlet and a outlet. on the fuel pump that was on there it has 3 ports on it. Ones comming in, and 2 going to the carb somewhere? Do i have to t those two off or something?

 

[Russ Johnson]

The fuel pump on the engine has a third port which picks up "pulses" in the crankcase and transfers them to the diaphragm inside. An electric fuel pump only needs an in and an out.

 

[RGilliam]

so what to do with that extra hose?

 

[Christopher]

Could you just leave the original fuel pump in place and install the electric fuel pump between the filter and the carb/original fuel pump?

Golf tee, bolt, etc...
