what's everyone doing for fuel pumps these days?

I've ran a walboro 450 e85 compatible pump in tank for 2 years now without issue for my injection conversion. I ran thick wires from the battery straight to the back, and had to upgrade the fuel pressure regulator as the flow of the pump popped the stock membrane after a while. Apart from that reasonably quiet, and unlike the 255 ethanol capable;)

Hi, I agree with "Janspeed" about the Japanese manufacturers, the quality control is really excellent. When I need something from the parts I go to the Japanese. But there are many other manufacturers that are just as good, see what suits you !!

I also went AEM 340 e85. Its quiet. I have read some reviews that the included submersible fuel hose burst and may be of a lower quality. Im using it without a problem so far.

3.5 year follow up, AEM supplied submersible hose burst on the race car after maybe 500 miles of racing? lots of garage miles though.
 
I have been using kemso 350lph pumps made in Japan, the quality feels the same as Aem, feels heavy in your hand and are silent in the car. Oh and they are 40 bucks with all the installing parts. I have sero complaints and I live in AZ, where the heat will destroy a cheap one. Havent had any of them for very long.
 
Bosch 911 608 102 02. Requires Porsche pn 928 110 47 50 Y nut, an M12x6mm Cohline banjo fitting, and some 6x8mm poly fuel line from my favorite metric hardware supplier. You have to rework the bracket as this pump is slightly larger in diameter than the stock one, but the result is a quiet, stock-appearing pump that will support 400hp, give or take.
 
DW300 for ~30k miles on 91 and e85 over the last 3/4 years. No issues whatsoever and I have another for another 240
 
Apologies for grave digging this thread but just wondering if there were any changes in the recommendations here? I need to upgrade the in tank fuel pump for 350-400hp and didn't have much luck finding more threads on this.

Also, is it best to leave the stock pump under the car or remove it and run the single pump in the tank?
 
Most aftermarket upgraded fuel pumps are a single in-tank unit. You eliminate the pump under the car. Upgrading the wiring to the new tank pump is a must.
 
When upgrading the wiring on a plastic hanger, what did everyone do on the outside wiring. I soldered new wiring between that top of the sender and fuel pump, but on the outside the wiring seems sealed in plastic or epoxy. I don't want to run a new connector through the top as I want it to look stock.
 
The stock epoxy-filled item can be removed so you can run larger gauge wire all the way to the pump, using a cable gland to pass the wiring through the sending unit.
