Who's Running a Walbro (F90000267) 416LPH E85 Compatible Fuel Pump?

Who's Running a Walbro (F90000267) 416LPH E85 Compatible Fuel Pump?

While everyone advertises that "in overall appearance the pump dimensions are the same" as the standard Walbro 400LPH Fuel Pump, that isn't true. The 416 E85version is approximately .405" longer in overall length than the standard Walbro 400.

Has anyone installed one and what modifications did you make to the fuel pump/pump hanger?



Thanks,

Dan (drb)

I have two of these on my Buschur double pumper. There was enough clearance between the bottom of the pump and the tank. Works fine and moves lots of fuel.

Thanks for the response. I can see where they could easily be used in a Buschur double pumper due to the modifications to the fuel pump hanger.

Still looking for information on what modifications anyone did to the fuel pump/pump hanger to fit a single Walbro 416. The only way I can see it fitting is to do the same type of modifications to the hanger that you do for a Walbro 400 and in addition cutting a considerable amount off of the long fuel outlet tube on the 416 fuel pump. My concern is sealing at the rubber grommet/fuel hanger/fuel pump connection if the 416 outlet tube is modified.

Pictures with dimensions attached.

To make the Walbro 416 E85 fuel pump fit in the EVO VIII fuel pump hanger, without drilling through the top of it, the 416 fuel outlet tube will need to be shortened by approx. .375".

My concern is sealing at the rubber grommet/fuel hanger/fuel pump outlet connection if the 416 outlet tube is modified. You could reduce the amount that the tube needs to be shortened by using a thicker gasket to seal between the fuel pump hanger and the car body.

I'm not sure if you can cut both barbs off the fuel pump outlet tube and still get a good seal using the standard rubber grommet. If you only cut one barb off the assembly may bottom out on the gas tank.

I'm either going to hack up a Walbro 416 or just buy a Buschur double pumper and be done with it.

It sure looks like shortening the outlet nozzle would do the job. With the larger OD of the E85 Walbro, I wouldn't worry about the lack of barbs on the outlet nozzle if you cut them off.

Dan what the hell are you doing lol. you're still fighting that fuel pump? also punch the bypass valve in on it that will help you greatly after 60psi~ of fuel pressure.

you are a boss.. how well does the car run with 2 walbro 400's in there, and did you modify the bypass valves in them as well?

i know a aftermarket FPR is 100% required (atleast should be) with a 400.. how much modifications did you do to run them both? did you enlarge the siphon and stuff?

Tom, I didn't modify the by-pass valves at all. Just put them in the place of the 400s I already had on there. One of the 400s actually went bad on me, so I replaced both of them with these. We did measure to make sure we still had some room were the sock met the bottom of the fuel tank, and we did. The car had LOTS of fuel after the install and made over 800 at less than 40lbs of boost. 38lbs to be exact

I'm not sure what you mean by enlarging the siphon. Could you explain? You know I've got an Aeromotive pressure regulator. I have two -10 lines out of tank into a Y-block and run -8 to the front of the car and -6 return, right?

The siphon.. the part in the stock housing where the 2 hoses connect to. its like a champagne color in the one pick Dan posted.

some people drill that bigger so the flow is more controllable. if you didnt have to do it then thats good. its mainly done when you try to run 2 pumps full time.

you have over 800 on that mustang at only 38psi? lol that mustang is retarded.. you will be 950 on a dynojet.

Ya so you run the Y feed with -10 lines then you run the other end of (straight hose to inline filter at -8?

i have no idea what the stock return is so i dont know.. -6 sounds right (for modified bigger).

-6 is good for 850-900 dynojet, so your -10 is good for like 1200+ id imagine.

so you put in -10 barbs on your double pumper or you had bought it with -10 barbs to begin with? mine look to be -6
