The 274 is the same pump as the 267, just a higher pressure relief valve in it. As was pointed out, we use the 274 since it’s appropriate on this platform but if you had a 267 installed, I wouldn’t bother to swap it unless you really have some OCD, are bored, or want to target higher pressures at HPFP/PI inlets.
I have fittings that will fit on your old pump. If you want one let me know, I have single (for bucketless or external second pump) and double 5/16 QD outlet fittings.
Double pump bucketed systems get TIGHT, not sure about the other guys but we trim the pump outlets and install our fittings for fitment purposes. Lots to fit in a small bucket!

I regret buying the Fuel-It version.
In stock form the 450 is a barb fitting. Fuel-It cuts that fitting down and threads it for their fitting.
I upgraded to dual 450's and the fittings on Dave's pump didn't work with the other parts I'd bought. So I had to buy another 450.
And my advice is to buy more pump that you'll need. Grow into it. It's such a PITA working in the tank that you'll hate yourself if you have to do it more than once.
