I've bought one of these,

2nd hand but unused so i have no instructions with it.
Got a couple of questions, Can the fuel in / out be plumbed into any side, and do you have to use the fuel return from the bottom of the reg or can you blank it and return it from the other end of the fuel rail?

Thanks for any input, Gary

I have a twin feed reg with a return at the bottom but a different make
Mine uses the twin feeds from iver end of my fuel rail as my rail is now centre feed but I was told I can block one feed on the reg off if I like
But at the guess I'd say the return will have to remain the return

I have one on my car.

You feed into a side port and return from the bottom If you try and return out of the bottom it will just flow fuel straight through with no control over pressure. The extra port if for engines with a 2nd fuel rail.

Used them a few times, never had any problems.

It's definitely at the pricier end of that type of product though. There are cheaper alternatives.

Return must be out of the bottom port, same with any regulator.

About 90% of these I see come in on cars normaly end up in the bin.

Oh poo, whys that mark? What would you reccomend? I would have thought that at just shy of Ł250 they'd be half decent?

Always drop pressure at full boost,
Bosch/Webber or Kinsler if you want what I called the best.

So basically, into the reg, out of the reg to the fuel rail and return from the bottom if the reg. so I need to blank one end of my fuel rail. Luckily I got a nice good ridge -6 blank then 😃

Any links? Needs to be a remote type as my fuel rail is -6 either end.

Kinsler is expensive.

No, typical would be into the rails, then the reg, then out the return.

And make sure any fittings you use are suitable for whatever regulator you use. Some might seal on the taper, an o-ring or a flat washer.

So I'd need to blank one side of the reg?

stevieturbo

Pretty much, yes.
