fuel pump leak

Ok, Leak appears to be coming from up the back of the pump. There are two drips at startup and when engine is idling. After short journey leak seems to stop. I shoved cloth in under pump and after 30min drive cloth was still dry. Could heat of pump have dried out cloth? or could leak stop when driving?
Also, can someone advise on adding acetone/glycerine to diesel in hope of fixing seals?
Regards
Isla

The cheapest fix is to install a drip catcher.
In its most basic form, mine consisted of a polythene funnel wedged under the pump (it doesn't get hot enough to melt) leading to an easily removable storage bottle residing in the under tray. once a week I pour the contents back into the tank. More recently I have incorporated a wider collecting aperture made from a 2 Litre sized water bottle which, again hasn't melted or caught fire. An additional rag i the under tray doesn't go amiss due to the diesel Bongo's characteristic oil discharge from the top offside area of the engine. The condition hasn't got worse and the pump performance isn't questionable. I've been running like this for years and using just under 2500Litres of veg oil per year!
My M.o.T man is satisfied that diesel is not being deposited in the roadway and that we are not dealing with a petrol pump.

Yup, Frank and me had this conversion a long time back. I found i could even leave a polythene drip tray resting on the under engine cover and it never fell off. Amazing cars these Bongos

I am afraid that your MOT man is a risk of loosing his ticket if he allows this fault to pass inspection.
Any leak in the fuel system is an MOT failure, even a missing or faulty filler cap is a Fail.
Take Care.

Point taken.
Luckily it it not always evident after a clean up.
My long term solution will be to use the Bongo to replace my current garden chalet which is a VW Type 25.
I'm in the process of being priced out of the motoring market anyway!

Great Idea , I saw one that was converted into a chicken coop, and the hens laid happy eggs.
Take care.
