Looking to replace my stock fuel pump.

If I upgrade to a Walbro fuel pump, would a tune be required?

I would still be keeping the stock injectors. Just doing a thorough stage 0 and would rather replace it before it dies and for peace of mind.

I'd be replacing it with this kit;

Walbro Replacement Fuel Pump Kit, Volvo 850, S/C/V70 - ViVA Performance

 

What year car?

I used to use Walbro, I don't anymore. They are very too loud for me.

I use Deatschwerks now, super quiet, 3 year warranty, get it straight from the manufacture, & etc. Get the 9-201-0883 kit.
