And I think Dandy should be beatified. To say you need patience (of a saint) for this job is an understatement. You need stamina too -

I think Dandy should be a tad worried about this as my dictionary defines 'beatify' as "to announce formally in the Roman Catholic Church that someone who is dead has lived a holy life, usually as the first stage in making that person a saint"
However I can confirm that north of the border the man is very much alive and is already regarded by many up here as a saint.
For example, a month ago my bongo suffered a catastrophic aneurysm and bled to death at the side of the road in a cloud of steam . Twenty minutes after a tearful phone call, it was all the kings horses and all the kings men, as dandy rolled up and put it all back together again - head hose replaced, full coolant change and all that that involves.
So I suggest we leave Dandy's beatification for the moment and knight him instead.

My lexdyscia saw that as beautified - I've just gone out and bought a load of goodies from Boots................

Just thought I'd add to this thread as I've just done this

To access the area a little better:

Remove the TPS parts (mark position beforehand though)
You can nudge the rear most fuel pipes a little to get your hand down the back

The O ring seals are R20 as per my O ring box selection. There are two one at the back & one at the front, which I'm not sure was made obvious in the original post???. I prized my rear most one out with a small blade.


The symptoms of this leak are a slightl hesitation to get started, so I assume the leak causes a pressure loss in the lines & it takes a few cranks to get the fuel pressure back up again?

TPS = what???

[dandywarhol]

Thanks for that capt'n. I hope your seals work ok - the Bosch ones are more squarish/oval in shape with pressure grooves in them - you can just make it out in the pic.

Going to have to take another look at mine - I can se a slight fuel weep at the same area again

Have you ever tinkered with the TPS settings??

[Captainsideways]

Not ever played with the TPS on a Bongo, never needed to. Though Have plenty experience with others especially Toyotas!!



My O ring seals were failrly deep in cross section & gave a good squidge factor when I closed the plates up, so I assume they'll be fine. Its been running & tested & all works good so far.

I like a good squidge factor capt'n

Hi,

just like to say had my seals done this week as dripping a bit of fuel, and the 'how to guide' was spot on. My local garage, who are clued up on Bongos (is that right, or is it 'Bongoes'?), said it saved some, but not all, of the skin on their knuckles! Many thanks

As an update to Dandys great post on replacing these seals. These are the ones that commonly leak.
A word of caution, around 30-40% of the time, other seals fail after replacing these. But that does mean 60-70% of the time, they don't.

You can now buy a couple of different seal kits from Bongo Land

Replace the seals mentioned in Dandys post.
Or replace this lot! You remove the pump to do this. Keep the work area spotlessly clean. I recommend placing all parts methodically in a tray or container.
Here's the seals you can replace if you remove the pump.
