What Walbro pump

[xnamerxx]

For the boosted guys, what Walbro pump are you using? I'm looking to upgrade but I'm not sure what pump fits and what needs to be done to install it.

I think most go with the 255, but that's way overkill unless you're making big power. I think the 190 is the better option.

My knowledge is only from memory of what I've read

I am using an AEM 320LPH. Deatchwerks makes a 300 as well. I skipped the Walboro route.

The 190 is more expensive hence the reason why so many go with the 255. According to an engineer I spoke with at Walboro he said the 190 could easily support up to 350whp in our application. He said going bigger would reduce efficiency as the returned fuel will be heated up during transit prior to obviously being sent back to the tank.
