I've been reading up on the 255 and I'm not sure it's made for returnless.

I'm thinking about just going with the Focus SVT pump, I can get that for right at $200 but a Motorcraft stock pump will run me a little over $400. If I could find the stock pump at a reasonable cost I would just do that and call it a day.

So yeller, your saying I may run rich for a while till the computer learns the new pump?
