Question Fuel Pressure Regulators?

Can you explain the differences and requirements please?

I'm getting a little cld be needed?onfused with different colours, ports etc...

I do know that are only two real contenders which are either Fuelab or turbosmart but which one.....

The FPR will be for a 2.1 stroker in a classic using either an sc42 or sc46.

Not sure which injectors i'll be using yet but this will be left in the hands of AJ and MJ who are building and mapping.

I'm currently stock piling as much as i can so it's all ready.

Also, while i have your attention, which fuel rails etc will, would you need to run for the best set up. The car already has an RCM fuel pump.

Thanks in advance....

Mine's an Aeroquip and works fine, recommended by Harvey.
Runs 3.3 bar above inlet manifold pressure all day long.

fuel lab 3 port so you can run a parallel fuel rail setup, you can use the standard rails and use normal fuel hose. All depends on how much you want to spend

Cheers Chris, I will be in touch once i've worked out what i need.

Alcazar... am i right in thinking you're running a 2.5 at roughly 450/450?

Banny, thanks. Does this one fit the bill?

Do you really need a 3 port for parallel setup? Can't you just use a t-piece and connect the return lines from the two fuel rails to one hose and connect that to the fpr just like you do to split the feed hose?
