Inlet & Outlet pipes

[cheeky monkey]

I thought id replace the fuel hoses for the inlet and outlet to to the carb (weber 32 DAT) as they were looking poor and evidence of a little fuel at the top where it joins the carb. Having put new hoses in its got worse, so i tried a lower bore size & different type of clips i still get petrol coming from at least the inlet but its hard to tell. putting the original pipes back on the prob is worse than it was originally. There doesnt seem to be any damage to the pipes coming out the carb themselves - or is it possible to get a hairline crack in these do you know.? 
Ive used a mirror to check around the area and its not coming from any gasket - they were changed recently and look fine.
any ideas appreciated

I test pipes by removing them and then blanking off one end and connect the other end to my compressor, then drop the pipe into a bucket of water and fire air through the pipe - leaks should be obvious.

Always use the same bore puipes if you can when replacing.

If the pipes are OK and I suspect the new ones are then I'd be looking at maybe checking/replacing the mechanical fuel pump or check the fuel tank to ensure that its not blocked the main fuel feed.

thanks Matt

the pipes seem fine and the fuel pumps been changed.. Its almost as if there is too much fuel being pumped through rather than anything being blocked.

Any chance the float level has been disturbed in the changes? Also the brass pipes press into the carb body I have seen them loose in the past. If this is the case remove it clean it and refit with permanent stud lock.

Righto Eric.. will have a look at that too.
thanks

It was the inlet pipe causing the leak.  Once refitted, although the idle was ok I couldnt get the ignition timing right, so Southern Carburettors who are very close to where i live sorted that out.  They have a similar set up to Northampton Motorsports who i think some of you know, with a rolling road etc.  http://www.southerncarbs.co.uk/  I would recommend them.
