help insall lift pump

[lightbuilder]

I picked up a new fuel pump, when I removed the old one I noticed the lever (atached to the new pump)that rides on the cam is a diferent shape. New one has a slight curve the old one is bent half way down at a right angle (looks like a hockey stick) any help would be great. thanks

You've got the newer style, it will work just fine. But, whether you have the old or new style you MUST follow the correct proceedure.

Fuel pump must be installed only at the low position of actuator cam.

If the pump is installed at any other position than low cam, the pump will be ruined, the engine will stall and damage may result.

Incorrect installation will loosen the pivot pin and allows the pin and lever to come out of the pump and drop into the oil pan. This can occur immediately or after several hundred miles. This type of failure is not covered by warranty.

To ensure that the cam is at low position, it is necessary to use a mirror and a remote starter switch. Observe the cam through the mounting port and bump the engine around until a one (1) inch wide machine surface is observed. This is low position of the cam. Now complete normal fuel pump installation.
Good Luck, OkieGringo

I did mine about two months ago and I had the same questions.

The low side of the cam will look like a small apple cut in half...with the flat side of the apple facing the ground. Turn the motor over a little at a time by bumping as Gringo said. I did this alone, so I had to bump the key, then climb under the truck to see if I got it into position, then bump the key, etc. Easier if you can have someone else bump the motor while you watch for the low side.

Good luck, lots of info in the archives,

Ya'll ever heard of a "Remote Starter Switch"? Hell, just hook to wires to the starter/GP solenoid, run the ends under there and touch the ends together. Come on guys, this ain't 'rocket science'. [img]/ubbthreads/images/graemlins/shrug.gif[/img]OG

can some one tell me why this is nescesary I can't see how you could install it in any way that would cause damage other then if you put the pump lever over the cam instead of under the cam but your going to know this right away [img]/ubbthreads/images/graemlins/shocked.gif[/img] [img]/ubbthreads/images/graemlins/shrug.gif[/img]oh well I laugh in the face of danger [img]/ubbthreads/images/graemlins/phoney.gif[/img] [img]/ubbthreads/images/graemlins/biggrin.gif[/img] I didn't bother with turning the motor and finding the low spot I just made sure the arm went under the cam [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

If the arm is off the cam and the bolts are tightened, it will break the pin holding the arm and it will fall into the pan..... simple as that. No replacement is offered under warranty should this happen.

EDIT>>>>>>>>
Due to the fact the arm is so long the days of popping it in the hole and tightening the bolts is gone I'm affraid. Alignment of the long arm is required in the right place or else.


Here's what the paperwork would say.......

This info pertains to Carter #M60278 pump.

copy that Guy I installed a new model pump about 10k miles ago I still don't see how you could put the pump in wrong the bolts line it up from side to side put arm under cam tilt up to line up bolts tighten down hook up fuel lines and 10 minutes your driving along happily [img]/ubbthreads/images/graemlins/shrug.gif[/img] I guess I'm a rebel and am living on the dangerous side [img]/ubbthreads/images/graemlins/biggrin.gif[/img] any how thanks Pete for the info it was the same that came with the pump good to know [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

This thread really helped me out. I was also having a problem with the newer arm design on the fuel pump. I didn't know if it was a redesign or the wrong part. Finally, I found this thread and mystery solved. Went back to the store to buy the part. The manager finally noticed the paper in the bottom of the box explaining the design change. Should be good to go now. Thanks.
