As you may or may not know in currently fitting EFI/ECU to my 131 sport.
Ive fitted the Throttle bodies to the 'Offset' manifold and i have a small problem.
Not enough room between bulkhead and fuel rail, so im looking for a 'straight' manifold.
Can anyone help?
Steve

Can't you turn the fuel rail input over to the other side? Seems to be enough room especially if you use a 90 degree fitting. Aren't you supposed to have a 'common rail' feed on this system as on twin carbs? (i.e. connect the fuel feeds together).

Parrish ,  looks very good indeed !!!

RE manifold , The tilt was to avoid the  block mounted distributor , 0of you put one in the head you will be able to put either a straight or a forward tilt manifold which will give you plenty of space.

I wish I could do it on my LHD .... Cry Cry Cry Cry

Thotos,
Yes its a common fuel rail that runs a return to the tank hence the connections at both ends, one will be an inlet the other a retun to the swirl pot,  its shown mocked up in the photo without the middle rail.

Miro,
exactly what im after, do you know where i can get one? ive fitted an ECU so no distributor at all.

So why not simply change the fitting near the bulkhead with a 90 degree one for the return pipe?

Theo,
the fitting at the end of the fuel line appears to be non removable, i am trying to get hold of another fuel rail to see if it can be done, but even then clearence is minimal. However i may have to see what i can do along those lines.

Djape,
carburettor connections look wrong.

130 Abarth one should fit as they only don't suit a normal 131 as the block mounted distributor usually gets in the way

a friend of mine owns this particular manifold. its 42mm dia. on the carbs flange side. since the photo was taken, it's been cleaned from grith and gasket remains. he wants 130e for it. i don't need it since i can't use it on any of my cars. when mounted on a rwd car, it gives a tilt of aprox 10 degrees up from horizontal to the carbs

djape,
no its definetly different, imagine the manifold on the engine, then look at the position of the top carb mounting points in my photo, they need to be wide apart, this manifold would put the top carb mountings close together?

Parrish,
