LS3 fuel pump?

[ATKY]

In the process of fitting a 480 hp LS3,can anyone tell me the best fuel pump to use?Also the engine does not seem to have a fuel pressure regulator or fuel return pipe,is it supposed to have these?The engine is a brand new crate item which arrived with a lot of parts,but very little information.Regards,Steve.

Bosch 044 is the best all round , and they are return less , do you will need a fuel presure reg

You need one of these, it's a Vette filter and tank return combined, I had to get mine from the US, maybe a UK Chevy/Vauxhall dealer may supply them

Some tw@t has posted pics of these regs on the net with the return pipe on wrong, so check before piping one up

Define your parameters for "best."
Do you have budgetary constraints, or is this more like a government military subcontract?
