Fuel pump probs !!!!!!

<< < (2/3) > >>

ginge:
Just held rubber back to turn star wheel but then removed it also to get a better grip on wheel ! Gave the rubber and plunger thingi a good pull !

Have just tried to set back to nornm and is still struggling to move.

If it aint broke dont try and fix it !!!!!!!!

ive got a sneaky feeling you have bent small actuater rod that runs on ecentric pin only properly accesable by top of pump strip

ginge:
Eventully got the diagham and plunger out, the pin which runs on the plunger is stuck in its hole and not following the plunger so no fuel. Any ideas how to encorage pin out or can i take top of pump off ?? Thanks for any replys.

biggerlandy:
bit of a fiddly job for you as you look at pump from top you see throotle lever with ten mill nut on it just behind lever on its pivot in the housing is a allen key grub screw. mark posistion of lever to relation of pivot or look closely on lever and you will some degree marks on it note where it is to the slot in the pivot and pull of lever carefull as lever under tension with spring. take out grub screw, spray lots of wd or what ever in back and on pin with a small screw driver jently push pin back out hole it may take a bit of doing. pin sits in a little housing clean it all etc push back to see if it moves freeley if so put all back together

ginge:
