Fuel rail upgrade?

[dylancorrea1]

I was browsing pictures of a new BaT Z and found what looks like an FPR that holds pressure.  Might be worth some research.  Picture 114.

Going to look into this regulator. Decided I will be changing the rail for a protunerz rail. When on sale their usually 90 dollars and come with all fittings.

Weird that that link is dead now.  It should have opened to a page with a couple of SARD FPRs.

Google shows them on eBay too.  I'd search around first and see if you can find any internet comments about leak-down.  Just because one didn't doesn't mean that they all don't.

Link works fine for me! On a form over function I like this one, looks like it’s standard fittings as well. Will do some more research on leak down.

Looks like the SARD might be like others.

But then this guy below says his does hold pressure.  I'm seeing that many people aren't real clear on things like the check valve inthe fuel pump.  The guy in the link above could have a check valve problem.

Shouldn't that RB motor have more psi than a 280? I have no guess but it seems plausible. 

Carburetors! 😁
