4AGE fuel rail

[merc-blue]

Guys im looking for some snaps and measurements of 4AGE fuel rails
measurements i want are just the spacing between injectors and height (rail and injector)
Cheers

this is a GZE one.
i included some measurements......
the total length is 295mm (thats minus the dampner)

THNX mate + rep for you
still looking for a 20V and 16v rail (should all be very similar?)

[slide86]

i would think that the 16v ones would be. but not sure of the 20v, i think they run side feed injectors. but not sure if that affects the rail type

[merc-blue]

i plan on using GZE injectors. but it seems ill have to make a custom rail, doesnt cost too much just a PITA

[roadsailing]

on a silvetop 4AGE the fuel rail is integral to (that means part of) the "manifold" (its not really a manifold but you get me)

they don't really have a fuel rail at all, and the injectors are side/perimeter feed as a result of this.

this is a GZE one.

the total length is 295mm (thats minus the dampner)

The 4AGE 16v rail has the same mounting point's and injector spacing as this one(4AGZE)Length seem roughly the same.
The dampner is in a different position to this one, the 4AGE 16v dampner is mounted on the top side of rail.
Dont have rail and injector hight, would involve removing rail

GZE and 16v GEs are the same, bar as bandit says the position of the dampner/pressure reg.
20vs are different, as they are cast into the manifold runners and are sidefeed.

Height is approximately 20mm

thanks guys. but it has become obvious to me that im going to have to fab up a fuel rail. as i was hoping this would would, but its not going to sadly. thanks to everyone for your info

[takai]

What are you doing?

[rolleraction]

There is a fule rail for sale on ebay atm

[merc-blue]

takai. i am building a custom intake/injection setup for a 3G/2TG hybrid. i was hoping the 4AG would fit but its abit off. the manifold isnt finished yet so it might go on. but i would rather be safe than sorry

Hm, you have me thinking now. Im starting to become more sure that the one which Slide86 has posted up is infact a bigport rail, due to the larger spacing between the middle cylinders.
Im also pretty damn sure that the smallport rail is different, and is a 89mm port spacing, due to the smaller port diameters.
The reasoning behind this was that i borrowed a bigport head to mock up all the wiring on my engine, and i remember that the injectors didnt fit in properly.

Im at work now, but ill check this when i get home.
Smallport 4ag Port spacing is definatley an even 89mm between the ports, as i had to build my airbox around that.

EDIT: Silly me forgetting about bigports.

[merc-blue]

Takai thats fantastic. i should be able to use a smallport rail then. measurements arent in as i said the manifold isnt finished but 89mm is damn close
the middle spacing was what threw me off initialy

[takai]

Yeah, it got me thinking about it, now that im more properly awake and dressed in clothes which dont smell of fuel and make my head go wooly. (coffee helps too)
