So my pump died a few weeks ago... had a new one put in but i went with the 255 walbro sense a whipple will be going on at some point.

Anyway the pump is fine, truck runs better than it did before, But ive noticed that if it idles for 5 min or so it starts missing and then quits... If you try to restart it, it just cranks... you have to give it some gas, Then its fine again...

So.. how would one go about fixing that problem.
