I use the Aeromotive:

Pro - More flow than DW
Con - Have to change polarity of power wiring for pump

Your con is not really a con since they fixed that issue. You only had to change the polarity on the first batch they released.

DW = 3-year warranty and E85 compatible.

Also, we have a 350Z specific fitment pump and install kit now available. The A340 and non-350Z fitment DW will require some trimming to make fit.

I tried looking for the app-specific pump, but aeromotive dont seem to go that in-depth. Is the 340LPH pump a drop-in? (aka, no extra parts/wires?)

I like both companies.

The only reason i would lean more towards the aeromotive is the fact that they have been making high hp fuel pumps for quite some time already.

DW has great products and fully tests their stuff so i wouldn't worry about them having quality issues either, though.

Not true. The DW301, W255, A340 all require trimming of either the assembly or pump to make fit.

We introduced the DW301 smooth bottom pump for the 350Z/G35 assemblies so that it would be a true drop-in fitment pump.

Also, the DW300/DW301 is a 320LPH pump that flows more than the similar in-tank pumps above 65psi. Which, in a FI application, is where you need more flow.

Do you guys have a flow chart? Not a graph but a chart?

Also off topic do you guys do injector servicing? If so can you pm me with prices and details.
