Fuel pump seals

[Simple Simon]

HELP !!!!
After 6 years my Bongo has let me down. Does this mean that it is unreliable and I should get something else?
Only joking.
Failed MOT on fuel leak and broken bracket on anti roll bar. Got the parts from the shop. I am trying to put the seal in the back of the pump by the blanking plate and it will not go. Both the seals I received in separate packs were a greenish colour and the same size. Is this correct. Main reason for asking is that the fact sheet shows a greenish and a black seal which looks a slightly different size.

Yours frustratedly

Hi Simon,
The black seal is the old one,the green on is the modified (new)one.You might need a wee bit of grease or similar to hold it in place.

Just to say that Ian advised me today that the club shop is out of seals until early July, on the advice previously given by Dandywarhol I contacted Lawson Diesel, http://www.lawsondiesel.co.uk/, and straight away the very helpful guy knew what I was needing, they are £5.93 including postage.

Looking forward to skinned knuckles already!

To give more room between the pump and the engine you can rotate the pump toward you after slacking off the the two 12m/m nuts that secure it. Probably best to undo the battery.

Your original advice (on another thread) included a reminder to use tippex to make the position accurately before moving anything. Was that to ensure the pump timing was reset accurately when job finished, as I gather that is absolutely critical to proper running. Most important that advice be heeded if so.

[Tripewriter]

Yes best to return pump to original position, however if running on VO or parafin, meths, ginger beer etc another position may actually be better. Movement is very small in terms of degrees and my guess is that bongos will run wherever the pump is but will not run well across the whole range of revs. Rather like the distributor when petrol cars had contact points.(god I'm old).

I like the idea of the "tippex" marking....useful as I am old school too.....used to do that trick with distributors.....however....should be checked with the relevant tool to assure absolute accuracy......
I had to have a new diesel pump at the end of last year and that was "dialed" in to spot on by Bell Hill Garage, who fitted it.... and to add to the mix....I run 20-30% veg in mine.... another thing to add.....since the pump was replaced......6 mpg improvement... so I guess.....use the tippex BUT get it checked for absolute accuracy at a Bongo or Diesel specialist...

[dandywarhol]

Diesel pumps - even old school pumps like Bongo (and Hiace ) need to be timed to the nearest 0.1mm with a DTI gauge

I have just done mine with a combination of the 'old' and 'new' loosen off pump method, what I did before loosening the pump was to gently hammer an electrical screwdriver at an angle where the pump joins the engine, I made a good mark, (not a scratch),on the pump and engine.

When I was ready to tighten the pump, I turned it until the screwdriver blade fitted perfectly into both marks, this ensures the pump goes back exactly to where it was, then held the blade in the marks until I had tightened the pump, simples!
