Alright before you commence flaming, I did search.

I have a single 255lph walboro right now. I need another (or a pair of different pumps). I plan on running E85 this summer and it takes a lot of fuel.

I want to run dual in-tank pumps. I don't want to d!ck with surge tanks etc. but am willing to consider an additional inline pump for a series setup. I would rather just hide everything in the tank though. I also don't want an A1000. I had one years back and it was so freaking loud, I couldn't tolerate it on my daily driver.

I am heavily leaning to another walboro, what do you guys think?

i have my mind set up on a bosch 044 in series whenever i get around to it. i think i'm going to run out of injector before pump anyways though. I too think the a1000 is very loud, but it could be a sacrifice. If you want to run dual in tank setup, i think the bosch is to big to fit in, so you may be stuck with dual walbros

I say run dual denso's.Thats what the Supra guys due any ways

The walbro's tend to to be hit and miss.Some say there not reliable and yet some swear by them.Me personaly when i go sigle turbo on the Supra will be running twin denso's.

Just make a dual hanger and drop in the tank.

I have had my walboro pump since 2005 or so, with no issues at all. makes me wonder if I got mine before they cheapened things up a bit. Sounds like there is room....
