Hi, right im having a bit of a mare at the moment, I bought an rover m16 manifold off ebay and the clown didnt send me the fuel rail, however i have got a plastic one from a later rover manifold (black ones with injection on the top)with the regulator on the end.Although addopting the metal m16 rail wouldnt be a Problem, I cannot understand how the fiesta turbo unit would go on this plastic one! any help-pictures would be gratefully appreciatted!

P.s how difficult is it to make aeromotive fuel rails and are the adjustable regs they do any good?

 

use the plastic rail and get a sard fuel pressure reg, sorted .

 

what leave the rover one in place and just fit this in line afterwards?

 

What's wrong with the Rover regulator?

 

dont they have to be rising rate, i dont know if the rover one is and also it looks tiny compared to the frst one!

 

yes thats how mine runs

 

No they don't and neither is the Fiesta Turbo one.

 

yes they do and the fiesta turbo one is as well

 

i drilled and tapped the frst one on the end of the plastic rail and worked with no problems, was adoddle too

 

lol, i thought they were.

 

No they don't. They are of a rising pressure type, not rising rate. They keep the fuel pressure constant across the injector, so when manifold pressure goes up/down the fuel pressure follows to flow constant amount of fuel in unit time. The rate of rising of the pressure is 1to1 (fuel to air pressure) and is constant. A rising rate regulator has a rate that varies with manifold pressure; the fuel pressure goes up more than manifold pressure. I've never seen or heard of a car that originally had one when it rolled out of production as new.
Rising rate regulators are sometomes used to compensate when standard ecu or injectors are retained after fitting an aftermarket turbo. A really cheapo trick that won't carry far.

 

ok sorry, but i meant rising type of 1:1, didnt even realise there was a difference lol

cheers for the help though
