IDI Fuel Lift Pump Alignment

[jhughes76]

Ok, I have been a member for awhile but usually do not start threads because I can usually find the answers to my problems in past posts, but a lil confused about something. I see some people say that you have to eye the cam and bump it over when installing the lift pump, and some say you can just angle the arm down and under the lobe and it will be fine. Why do some insist on bumping the cam until is is aligned perfect, and others say they have successfully just angled the arm down and under the lobe?

I have always angled it down bc I can't get a good look at the CAM with the space I have and id works fine. You will have to keep pressure on the pump to get the bolts started if the cam lobe is putting pressure on the arm, I imagine if You turn it just right You can get it to no put so much pressure on the arm and therefore easier to install it.

Make sure You get a good quality lift pump so You don't have to do it again any time soon.

Its a Delphi at the local O'Reilly Auto Parts.

I just put one on the other night when i was stranded in a parking lot. The install instructions that came with it were pretty good (Advance) and I just angled the arm under the cam. It was the first time I'd ever done one and it only took about 45 minutes, not that long at all.

You can get away with angling the arm but just be safe and put a bar on the crank and rotate it till the lobe is pointing up. then no need to worry. Just imagine how you would feel if that comes apart in your crankcase

The Delphi is a very good pump IMO, It doesn't have that funky arm on it either like the Napa pump I bought and some of the other ones I've seen.
