Supercharger AEM 50-1220 340 Fuel pump replacement by removing the bed

It’s actually a very easy process to remove the bed to get to the fuel pump.
I installed the AEM 50-1220 340 pump (supercharger) its almost identical in size to the Denso pump
Rented this Pittsburgh engine hoist for 25.00 a day. Can do this in one day easily.

Remove the taillights
Remove the taillights harness
Remove the gas cap and remove the gas filler section
Remove one tire for the hoist to slide under,
Remove the six bolts holding the bed to the frame.

Nows a good time to clean your frame from rust and spray a coat of paint

 

You can also just slide the bed back a couple feet if you don’t want to mess with a hoist. Still easier with two people.

 

After removing the 6 bolts that hold the bed to the frame, what do you have to do for an hour before you can get to the fuel pump?

 

Did mine the same way...there was no dropping the tank with a rusted strap. Pretty easy to lift the bed off with two people as well

 

Just cut the bed and make a service door like a 4Runner

 

You paint the frame of course

 

Yup, winter is. Coming so I figured this would be a go time to paint the frame.

AND of course that gas line nut was to the fuel pump needed a 4 foot breaker bar to bust it loose

 

I think you can remove the front and middle bolts, loosen the very rear bolts as far as you can but leave them in there to hold the rear of the bed in place and then lift the very front
Of the bed up just enough to get the pump out as long as the fuel lines break free.
You probably need to remove the gas filler plate

 

What's the difference or advantage between the AEM and Walbro 190lph that most route for after supercharging?

 

The Walbro out put flow rate is 190lph and very loud.
AEM 50-1220 out flow rate is 340 LPH not loud = 95.00 from advanced auto with discounts.
Zero ping issues with this AEM pump

 

Not to discredit you but I run the walbro and honestly don't hear the "loud" part of it..? I guess my magnaflow is interfering. There is a slight hissing when idle is warmed up and the environment is quiet but I can live with it. In fuel demand with the average pulley size used 2.2 to 2.1 do you see an issue or is it just preference?

 

I don’t have any experience with the walbro, I’ve heard plenty of people say it’s loud.
I run a 1.9 custom pulley with stock injectors, again no ping or fuel issues with the AEM pump, it’s output is much higher

 

1.9 pulley with stock injectors really?? Wow.. Did you have to create a map or have it tuned, 7th injector?

 

I am running a stand alone haltech 2000,
The haltech has a timing map, fuel map, no open loop or closed loop to deal with and no MAF to deal with.
The AEM pump has more than enough extra fuel pressure to cover

 

Crazy AWESOME! I know Haltech is the tuners choice for complex turbo setups but never knew of anyone doing it on the Toyota 3.4 supercharger configuration. You're at an ABOVE level my friend..

 

Thanks
The haltech has solved all the supercharger ECU problems and the power comes on IMMEDIATELY.
No closed loop anymore.
A new band of power in the lower rpms.
It has a completely new power band now.
You can swap it back to stock in less than 10 minutes too if needed

 

COOL.. I'm not unhappy with my current combination but you must have a smirk from cheek to cheek , nice to know. Not sure when but I'm gonna have to follow in your footsteps. Hahaha..

 

Well if you do there will be a big improvement over your setup now,
When you get to that place let me know and I will give you my advice and some inputs on what steps you need.

 

THANK YOU, will do!
