Fuel Leak

[Siban]

Hi,

Fairly recent owner of a Fiat 124 CSO and I've just noticed I've got a fuel leak where the arrow is on the picture below.

Cant see any obvious jubilee clips and anything to tighten so being particularly ignorant on Fiat mechanicals I thought I would post the problem up here. Anyone had this before? It's connected to the fuel rail but have no idea what this particular connection does I'm afraid.

Any help much appreciated.

Want the good news..... it is #1 injector, easy to get to.
What happens with time the injector hoses get brittle and will crack. The fuel is going through there at about 35 psi and will leak with a bad conection.
What I'd recomend you do,it can be done easily, is to pull the injector rail off with the injectors still on and on a bench swap out the hoses. The vendors here all sell kits I believe that have every thing you need. There are 10 mm nuts on the intake manifold holding the injectors in place and a few hose clamps to undo, and the main fuel line. Getting the old hoses off can be fiddly as the injector has a "barb' on the end,I use a box cutter and plyers. Make sure you purchase proper fuel line clamps as the standard screw hose clamps can pinch the line and you could be back doing a repeat.I will wrap the cold start hose with a rag and undo that first as the lines might still be pressurized. The starter and alt are below the fuel lines so before you go driving too far this should get addressed.

Chris,

What a great response and I really appreciate the time taken in responding in this detail.

Many thanks,

Whether or not pulling the fuel rail and injectors out is something done easily is going to depend a lot on how patient and calculating you are about it. Just don't expect it to be done in 5 minutes, make sure you cut the correct length of hoses, have the correct thickness of hoses, don't round out the nuts that tighten the injectors onto the intake manifold, etc. and it will be smooth as butter. I only say this because when I rebuilt my fuel rail it turned into a huge debacle and I ended up taking it out, changing the hoses, and putting it back in roughly 5 times before all of the injectors sealed properly.

My experience a while back with refitting the injectors with hoses (along with dealing with some other issues) is chronicled here. You might not feel like reading the whole thread, but if you do I'm pretty sure you'll be an expert on properly putting everything back together correctly.

Most major auto supply stores have a section with "HELP" cards. These card have universal replacement parts. Card # 90100 is a fuel injector seal kit that contains the upper and lower seal for the Bosch injectors. One card has six sets of seals for numerous types of injectors, so it contains stuff you don't need. Last time I purchased a card it cost less than $10. I have used these seals with out a problem on a number of FI Fiats.
