Title: more help!!!
Post by: TELBOY on March 26, 2017, 04:42:48 pm
Can anyone supply a picture of how the 2.2 sills are mounted to the chassis, I need to know how the front is secured as mine were fitted using a strip of metal riveted to the front edge and then to the body? Thanks

Not sure what silla you refer to. Post a photo of the ones you have issue with.
I have a parts catalog that may show exploded drawing of how they are assembled.
I will dig it out when I get home.

Send a picture of what you have and I will send you what I have. Mine is up on jack stands with wheels of so I can get lots of piccies if you tell me what to take them of.

I fitted my "S" sills at the front using the existing rivet holes (used rivnuts) and nothing else....

Thanks Gib....that looks neat! Mine are also off a 2.2 but were on my the donner. they were secured by a straight piece of metal riveted to the front as can be seen by the 3 holes at the front. your picture gives me a good idea of how to fix them. the main picture shows them almost reAdy to fit to EOW

They started life as white before prepping, priming and spraying! the rivets don't line up perfectly so any chance of some more close ups of the front showing how flush they should be to the body at the front edge.... :)

As work has been progressing on EOW (1.9 pug engine) I though it was about time I made sure the engine was fine as I have only started her a couple of times. I was aware the fuel pump had been repaired (This I was told when I purchased her) so it was no surprise when I turned the ignition and.... no fuel getting through! I purchased and fitted a universal fuel pump, changed the fuel and she fired up very easily. However, the carb (a twin choke) leaks fuel after the chambers fill! Is this because the float chamber floats are set incorrectly or the fuel pump is too powerful? Should there be a pressure regulator fitted somewhere? Advice needed and welcomed.

Try cleaning the needle valve in the float chamber first.  If that doesn't do the trick it could be the incorrect pump.  Assuming the car was running ok originally, the float level setting won't have changed.

You should have a back-flow valve if you use an electrical fuel pump (I do). If not you are probably overpowering the float valve's ability to close.

The original mechanical pump fitted to that engine (Pug 1.9 carburettor) did not have provision for a back flow, although the original Matra setup did.  If you have fitted an electric pump, the solution, as Jon suggests, is to re-instate the back flow or to install a pressure regulator.  Most carb needle valves cannot withstand a pressure of more than about 3 psi.

Thanks gents.. I just removed the old pump and replaced with a new one.  The fuel pipe went directlu to the carb with no regulator or valve!  There is no return pipe crom the carb either.  I will do a little research on pressure regulagors and valves.  Will keep you posts and again thank you.   Terry

For older Simca there is also the pump without return mounted.
Before the carb a T-splitter is mounted and the return pipe needs calibrated at 0.7 mm for return .
Ofcoarse that is the rule for the original 1.6/ engine/Weber with a pump that generate 0.3 Bar.
