Walbro 274->295

I have a 274 in my stock bucket now. Looks like it is struggling to keep up with hybrids at 21psi on E35. Can I just buy a 295, drop it in with no issue and just go? I am not looking for world beater power, and 20-30% more fuel on the low pressure side should be fine for what I need.

I know about the no check valve on the 295. Are there any other parts I need to replace during the swap?

Do you think it's possible that your EKPM is not providing enough power to properly feed the 274 currently?

I doubt it. Pretty new EKPM3 that is coded and updated with latest firmware. You can see up top LPFP starts dipping into the high 40s. LPFP is bucketed, so I think I am just at the limit.

It'll work perfect! The 295 is a great pump. No check valve is a non issue.

edit: i'm bucketless though. Maybe just converting the bucket to buckettless will give more flow without pump upgrade
