Advancing Fuel Pump Timing

Slybacon · Post by **Slybacon** » Sat Oct 11, 2008 8:56 pm

Does anyone have any advice on advancing the fuel pump timing? I have dial gauge and the timing pin. What I'm not sure about is:

a) The initial correct setting
b) How to advance the timing by 3 degrees using the flywheel marks - e.g. does each mark = 5 degrees?
c) Will it be the same as for an L200 (seems to have the same type of pump)?

The reason? I'm running on 100% WVO with a twin tank system and the old girl is hunting when idling and its a bit annoying when sitting in traffic.

Thanks in advance ( did you see what I did there?)

I suspect people are out enjoying the good weather. Personally, I've no idea what you're on about

You're probably right!

On the flywheel there are timing marks - what I need to know is what position it should be in to set the injection pump timing - once I know this I can have a go at advancing it.

Hi is it the engine timing you are looking for,ie tdc/btdc.
If so Dandyworhole may have the settings,or someone with a workshop manual.

Hope you get it.Mal..

Hi, can't answer your questions but I'd be interested in the answer as i've got the same problem at idle running 100% SVO. When I changed the cam belt a while back I used the flywheel timing marks, much easier than on the front end. You could confirm what degrees the dashes indicate by estimating the flywheel diameter, measuring the disptance between the gaps and doing a bit of arithmetic.

Yes it is TDC I need to know - Can I assume the first mark on the LHS indicates TDC?

Thanks Smitch - doing the Math does make sense! Sitting in my kitchen at 12:35am - I'd say the diameter is about 300mm? The distance between the gaps about 5mm. So the circumference is 3.14 x 300 = 942mm, which means each division is 5/942 x 360= 2 degrees (approx). If anyone has any more accurate musing please chip in!

I'll post up results once I try it.

Sly - PM me your phone number and I'll call you with details of the pump timing - too much to post up on here
