Yes on a new pump, IMHO. They don't cost a lot.

There is some occasional bru-haha over standard versus high volume pumps; they are only 20% different on the flow capacity for the SBM ones. The HV will have better pressure at idle and lower RPM's but they are really not all that much different.

Per some info on FABO, the Mellings all have the higher pressure relief springs, at around 72 psi. I personally would go for that for regular street engine use.
