Fuel Spraying out!!

Post by **bouncingoffthewalls** » Sat Jun 27, 2009 4:31 pm

Hello,
My Moggie doesnt seem to manage a week without a problem at the moment!!
oh well... lucky i love her... oh and she is a 948 engine, 1962 morris

when i turn on the ignition, before i pull the starter putton i get a clicking noise...

then i started getting fuel spraying out - all when i turn the ingnition.

the fuel is coming from a small cylinder which sits next to my air filter, and infront of the carburator - so am assuming it the fuel pump.
(am sorry for the lack of knowledge!!)

so i went and checked the hose connection to it (a black hose coming from another black cylinder attached next to battery)

but connection is fine it seems like it some how coming out from the pump...

any one had this happen?
is it the fuel pump?
is it easy to fix??

oh and i successfully changed the dynamo on her the other week!! was most proud!!

thanks heaps guys!!
karen

Hi Karen, that part is the float chamber. It has 3 screws on top of it and the top lifts off if you remove these screws. The float is attached to the top that lifts off. The bit remaining is the bowl. There is a seal between the lid and the bowl which may be worn out or it could be that the screws just need tightening. ps, the black cylinder by the battery is the actual fuel pump.
HTH, Rich

Link to workshop manual sent by PM Karen - happy reading! Until you get this sorted - best not to start the engine - it could cause quite a fire. As above - the petrol is coming from the float chamber - there may be a little bit of dirt jamming the inlet valve - clean it and then try again.

okay, have cleaned it up and tried it again, the fuel is coming out of a little hole under the hose connection.

It appears that the float aint floating!! It has a little bit of liquid in it - is this normal??

thanks again

No - it should be empty. If it's the older metal float you should be able to get the fuel out (boil it up in water - or leave out in hot sun) and then solder up the hole. Newer plastic type - no option but to get another one.
BTW - No need to print out the whole manual (save trees!) - just hold it as a pdf in your computer - and print out odd pages as you need them at the car.

I'm sure subsequent advice about the float itself is on the right lines, but in case anyone else sees this thread, I'd beg to differ about the float chamber lid seal. It's a seal against petrol slopping around during movement of the car, not against the sort of pressure that could cause "spraying", so at worst, deterioration only leads to a weeping of fuel down the bowl. There's a risk of stripping threads if you overtighten the two or three screws that hold the lid on.

If your lid is secured by a single banjo bolt, with an overflow pipe (some 948s?) do make sure the overflow pipe is routed to somewhere sensible. I saw a Mk VI Bentley recently where the owner will have learned a lesson about routing an overflow pipe directly at the sparky end of the dynamo...
