<VV> Fuel Pump Eccentric

[Joel McGregor]

.037" ??  No wonder people replace those with electric pumps.  I guess mine are all non-stock.  I would guess they travel .370" :-)

Smitty Says;  I don't have a answer about removing the eccentric in the car.
I do have a word of caution for you though.  How do you know the eccentric
is worn out?  Did you measure it with a dial micrometer?  The stroke of the
pushrod is only ..037 inch with a new ecentric.  Most people expect it to
move farther than that.  I have seen a couple of cases where the damper was
night tightened all the way in, allowing the eccentric to wobble and not put
out a full stroke.
