Carbed hp500 fuel pump
I have a velocity 280 with hp500 and KE performance mechanical pump. I'm losing fuel pressure over 4200 rpm
dropping to 2-3 lbs. What fuel pump would you recommend to solve the issue?

How old is the pump. Did you ck to see if you can just purchase a rebuild kit? Otherwise if it's served its purpose and want to replace it I'd just replace with another KE or compatible gph Holley.

Do you know what size fuel line the stock pump takes? I have all -8 line now. I put a replacement pump on and solved the problem but it only has 1/4" line

Worse case scenario in your situation you might see a C hair loss in pressure however I highly doubt it.

Just another reassurance the pump you bought I would have to imagine is over 100 gph which is over double of what you'd need at wfo. If you were running 1/4" fuel line and 90 deg fittings then I'd be concerned but that's not the case.
