Heavy fuel leak from top of engine

[Meles]

Hi all,

Been plodding away with my van conversion. Have fixed the sliding door alignment issue and fitted some wind deflectors etc.

My van started heavily leaking diesel while pumping. It appears to be from a little black plastic ‘node’ coming off the 4 branch fuel line. Could someone tell me the name of this part and if it’s easily fixed and/or requires a replacement part, please? I have been searching online but haven’t found this issue elsewhere yet. I tried to pop it back together onto the injector (?) but no joy and I’m terrified of messing about forcefully with an area that is spilling fuel once engine running. Battery is dead now too so a bit stuck getting it to garage as feel jump leads could be a spark risk!

Looks like that could be the leak off pipe from the injector where the 'leak' is coming from. This is basically where excess fuel is sent back. It can be a fairly common issue. Not expensive to fix. Any GOOD garage will be able to fix this. But do not drive it with such a heavy leak. Don't be concerned about spark risk as it is diesel, and will not combust / ignite in the same way as petrol.
Ideally need to get it transported to a garage, or have someone come out to you.
All the best,
K

Many thanks for the reply and it does look like the leak off pipe, cheers. I've watched a video of someone replacing the O ring on one on different vehicle and guess my van needs similar. I unknowingly drove about 15 miles with that leak (could forensically retrace my movements back to my house!) and it should really have clicked a bit sooner when my fuel was dropping rapidly. Then, in my ignorance, I initially thought it was as sump issue but the beauty of taking a video was that i could slow it right down to locate the initial occurrence of the leak prior to me being able to get round to the front of the van.

push it back in

its came away for some reason

may be the clip as gone that holds it in place

temp repair is push it in and cable tie it securely to the injector

Just seen that the R-clip is still in place (Brass colour Poking out in photo opposite my finger) so will start with replacing O ring. I saw a video on YouTube undertaking this repair and by looks Of it I can depress the R clip so don’t have to extract it and the poke it back through afterwards.

the actual pipe could be worn hence y it doesnt stay in play

cheap enough brand new ofhttps://www.ebay.co.uk/itm/164962362506 ... SwxfBg8Rrj

Thanks a lot for the part recommendation. It would seem economical to change the whole thing assuming that it’s something wrong with the line.

I pulled the problem connector out and the green O-Ring seemed to be intact although perhaps there is something subtle that is wrong. The R clip felt a wobbly so could be that the pipe itself is out of shape and therefore not held in place.
