Fuel pump - no petrol

[sebking]

Took fuel pump off to fix the massive oild leak only to discover that it is far from flat across the mating surface - and gasket is now damaged.<br>
<br>
I need the car on the road for Friday am for an important meeting so grabbed a tube of instant gasket (emergencies only) put pump on - now there's no petrol coming out (yes there is petrol in the tank)<br>
<br>
Pump works on the bench, has now been in and out three times and still cannot work it out.<br>
<br>
(it is the no spacer variety)<br>
<br>
Any ideas - what's going on?<br>

....when you are offerring the pump up to the block the operating arm is missing the cam on the jackshaft; its very easy for it to slip past the side of it. Try again, but do the two bolts up incrementally. Trial and error I'm afraid - they made the cam wider on later shafts!

I have a pump and an engine how do I find out whether they are happy together?<br>
<br>
One pump covers 73-78 the other 78-80, car is 79 but engine is who knows what...<br>

There is no issue of non-compatibility with fuel pumps (as far as I'm aware - I may be about to learn something though!) just that the later jackos with the wider cam made it easier to locate the operating arm correctly. I've had this problem myself and it took three attempts at fitting to get it working. If you move the pump side to side as you offer it up you can feel the cam location with the arm. With the narrower cam you can miss it all together AND still get the mounting bolts aligned, in which case it won't pump the pump. You have to do it by feel I'm afraid.

I have replaced fuel pumps on 1500 & 1850's in the past.<br>
<br>
2 experiences come to mind.<br>
<br>
1) As already stated - ensure the cam and leaver meet up.<br>
<br>
2) If you are in a rush - check you have the fule lines going to the right sides of the pump. get it wrong and you can be pumping to the tank, rather than the engine - silly mistake, but it is possible! <!--EZCODE EMOTICON START :o --><img src=http://www.ezboard.com/intl/aenglish/im ... rassed.gif ALT=":o"><!--EZCODE EMOTICON END--> <br>

Alun is correct. It can take ages to get the flippin' thing lined up. I've also had the arm fall to the side of the cam whilst driving hard, so now both my Sprints are fitted with Facet elec. fuel pumps. One less thing to worry about. <!--EZCODE EMOTICON START :lol --><img src=http://www.ezboard.com/intl/aenglish/im ... /laugh.gif ALT=":lol"><!--EZCODE EMOTICON END-->
