Twin walbro pumps DIY
Remove facotry assembly
take the second pump and strap it directly next to the existing pump, use the hose clamps that you tighten with a screw driver to mount it. I used 2 clamps. youll notice once its mounted right about it is a semi flat area. take a dremel and cut away the lil pieces of plastic to make it totally flat. now your gonna need to get a -6 bulk head 90degree fitting. drill a hole where u just cut away the plastic material and attach the bulk head fitting with teflon washers and some honda bond.(i used orange silicone).
Now take a -6 push lock fitting straight and screw it on to the threads that would be in the tank. the way the pump sits the outlet should be just about lined up with where you put the bulk head fitting. cut some hose and attatch it to the pump outlet and -6 push lock fitting.
make sure u get the pump that will let you put the strainer on facing the factory strainer.its like a lil bath tub in the tank so if the strainer faces a diff direction it wont work.
it will take some finagling to get the pumps back in but it will go back in.
wire the pumps however you would like..
ill get some pics this weekend...
I assume no responsibility if you burn your car to the ground.
I run 1 pump for either side of the fuel rail and return in the middle,
might wanna throw a check valve on either pump line so there not fighting each other.
hope this helps

You dont put anything rubber between the two pumps to make sure they dont vibrate against each other?
