Aeromotive released a new in-tank pump

Pretty cool little pump. I may be swapping out my walbro for this. They have it in a kit for the 240 as well.

I may be picking one of these up too.

If anyone is interested in these, I carry Aeromotive and can get you some pricing.

I'm definitely interested, lol. How is your pricing compared to Summit's $169.95 + Shipping?

[PerilousActs]

I can beat that. I'll pm you a price.

[2_Liter_Turbo]

Nice!

I understand its 340 rather then 255 for the walbro, what are the real benefits?

[Matt93SE]

Reliability. The Walbro flows more than enough fuel for just about every engine you can use in a 240, but I've heard the newer Walbros are now Chinese-made and are prone to failure at the worst possible moment.

Cody called me about this over the weekend. We're looking at doing a blow-out price on these for a while for those interested.

[croustibat]

it seems it cant do alcohol, but maybe that was about methanol? I am using bioethanol fuel (ethanol) and ... lets say i dont really like my walbro chinese copy.

[leetfade]

Excuse me if I sound like a complete idiot here, but are you running E85 or are you referring to more like an injection for cooling (alcohol / meth injection)? It's E85 compatible from what I'm reading.

Never had issues with "Chinese-Walbro's". Fuel pumps either work or they don't.

Thought I'd buck up for an OEM Nissan 300ZX pump on the old racecar, and it lasted all of 17 minutes.

Since then, been running Circuit Sports/Walbro's in all my cars including the race car, and have had zero issues with them. On the SM racecar, I run one into my surge tank and then a Bosch 044 out to the fuel rail.

We sell hundreds of Circuit Sports pumps a year.

BUT if you are planning on running 400+ whp on your car, you will require more than 255 Walbro, ALONG with increased fuel line feed lines. Running less than 400 WHP and going to a larger pump is not needed as the excess fuel is just returned back to the fuel tank.

Afaik walbros reliability issues are related to running the pump dry. Apparently the fuel's cooling+lubrication is more critical than other pumps. Internet folklore claims it only takes one gasp of air to start the timebomb.

My walbro has 5yrs and 25k miles on it. Its never been starved, but it is getting louder with random dips in the pitch (steady V). I keep a spare on me just in case.

[Matt93SE]

Internet folklore is wrong- at least for my Maxima and my S14. I've been running Walbros in them for a looong time, and have run the car to starvation in corners dozens of times, and run the Maxima out of gas on the highway twice. They're still going!

If I get my aeromotive pump WPC treated will it last forever?

With that milky lustrous surface, it will have to!

The last time I saw a Walbro fail was back in the 2004-2005 era when they just hit the scene with S13 apps. In all fairness, I've seen just as many Aeromotive A1000's fail. Some of that was user error though. One guy burned up 2 before he figured out that he was supposed to gravity feed them.

I ran a Tomei 280 pump on my S13 with the Defi differential fuel pressure gauge setup. You could watch the pressure count down as the power went over 400whp. That was with stock hard lines, 50psi base, 20psi manifold. A 340 would have fixed this, but probably would have needed a -6 braided or -8 hardline from the tank to see the full benefit.

Spent the money on a Supra pump for the S14. Install was easy. I would have done this Aeromotive had it been available, though.
