Have 800hp blower morors and need input on mechanical fuel pumps. Has anyone tried a Race Pumps brand mechanical pump. The fuel system the boat came with consists of Holley blues of which I have no faith in. There is piping and fittings that where once used for a return to the tank fuel system but have been capped off?

Which ones are marine rated and CG certified? If you value your insurance these are important questions.

The Sx-performance Part Number 18203 Is C.g. Aproved

Do you have any more info on these pumps? I would like to upgrade to a mechanical as well but I will need a gen 4(in the block) and a gen 5(in the water pump housing).Do they make them in both styles and whats the pressure and flow rate?

Thanks Nordic95

same question, & what is the price?

Pretty nice site........

i was wondering the same, what are the advantages/disadvantages of mechanicals vs electric, im running a similair setup with blowers also, and need to do my fuel system, with a electric do i need a return line going into the tank?

Unless you dont mind buying pumps, always run a return line.....
