Default Rigging Holley Sniper with better components?

I’m 99% sure that I’ll go ahead with the Holley Sniper on my 509. It comes as a complete kit with a Walbro 225lph pump, filters, and misc clamps and hoses. It seems to me that this is pretty light duty stuff for a marine application.

Thoughts about using the supplied components or find a better fuel pump and filters? One reason is the kit uses hose clamps which I hate. I much prefer push on/an fittings. The main reason is that I’d rather invest in better components and do it just once.

You might want to build your own system starting with the pick up, size to your projected HP. Maybe use the FloMax 300M filter / water separators.

Currently have the Hardin filter head with 1/2” fip to -8 line to the tank. ~600hp in dyno trim.

Nothing wrong with walbro pumps...but that pump seems small for a 509 depending on your goals.

225 lph = ~ 358 lbs/hr gasoline

358/0.6 BSFC = ~ 600 hp......on the edge not having a pump curve (or fuel system to estimate line pressure losses) to double check, regulator pressure and not knowing the specifics of your engine,

Id run a bigger pump (depending on goals) and use parker pushlock plumbing (JIC = AN)
