Hey all,
Got a few questions regarding the setup of a quadrajet on a red 308.
My question is regarding the fuel inlet line. After the pump, I have the usual clear fuel filter fitted, which then feeds into a brass piece attatched to the carby which resembles a kind of diaphragm (Have photo's if needed). It has on one side the inlet attached, and on the other a "fuel vapor" hose, which is cut and plugged by a screw. My question is, where should this fuel vapor hose go ? As I mentioned at the moment it is cut and plugged, and I noticed the other day that when the carby had an excessive amount of fuel (flodded), it began to leak small amounts of fuel from this house. Do I need this second diaphragm and if so where should the vapor hose be connected ?
Cheers,
HZSandman

according to my manual it goes off to the carbon canistor.
99% of people dont even bother having that part you mentioned on the fuel inlet attatched anyway so y ou could take it off if you wanted.

Hi Guys.
That little fitting coming off the small diaphragm on the carby fuel supply line, is the fuel return line to the tank. DO NOT CONNECT it to the carbon canister, as it supplies a contiuous stream of petrol.
It was only originally facto

Thanks for the comments! I thought that might be the case, but was reluctant to discard the diaphragm incase it was a vacumm control to stop the fuel supply to the carby from continuously supplying. I previously had a 253 in the panelvan, and after I had

Your inline plastic filter (ryco) should be befor the fuel pump as any grit will start to perish the rubber diaframe. also the preasure side to carbi has to be all metal pipe/ screwed fitting by law as the early cortinas had a habit of spraying fuel over

The problem with the cortinas was the fuel pipe in the top of the bowl was a press fit, and the pipe would work loose and fall out. Had this happen to me twice, once I discovered it the second time one burnt Cortina (best thing to happen in my opinion) w

I thought that the difram lookin thing was a filter? i pulled mine off the Black 308 i had. was always getting clogged. i just put 2 good quality filters instead of this one, and the carby had filters in it anyway

Dr Terry,
I have this setup on my factory air 308 HZ also, so why did the aircon models get this and the non aircon ones didn't??

Hi Peter.
The A/Cond car's engines run hotter in traffic, on hot days, creating possible fuel vapourisation in the metal fuel lines.
This is an easy way of getting any vapour created (or even hot fuel) back to the tank instead into the carby.
