At half track I get really bad surge (like it's running out of fuel) but if I lift off off a second then hit again it's fine.Is the pump to low for that power levels? I'm thinking of putting the 420l pump in but need more info.1. Will it fit in (I.e swap over without having to re wire pump considering there's a walbro there now)?2. Is it worth putting a higher pressure reg in?3. Can this be done without having to put a surge pump in (don't have the space for it... Kids etc)?Thanks Link to comment https://www.fordxr6turbo.com/forum/topic/88554-walbro-in-tank-dying/ Share on other sites More sharing options...

Benny Member 1,869 Member For: 21y 10m 8d Gender: Male Location: Newcastle Posted 20/06/14 10:24 AM Share Posted 20/06/14 10:24 AM ^^^ What he said. Walbro 460 intank is the go. Much easier and cheaper than a surge setup. Installing a Reg on its own won't prevent the increased pressure of the bigger pump. There is a restriction in the return line of the swirl pot than will limit flow and increase pressure. This can be corrected or you can have your tune adjusted to accommodate for the higher pressure.
