I had a stud back out behind the pump and am pulling the whole pump to replace the $2 stud.
While I have it apart I was wondering about modifying the timing.
I don't see how you could do this except by twisting the pump on the studs after it is installed.

How do you adjust the timing on one of these?
Internally?

I know how to adjust the low end pressure and high end pressure by modifying the pump. I have never seen much about changing (retarding) the pump timing.

you want to advance the timing by pushing the pump towards the block past the timing mark on the cae by like 1/8 i think is the distance. i think there is like 4 bolts you losen to push the pump over. but since your tacking it off anyways just park everything and find the timing tick mark and got 1/16 or 1/8th past that. its really personel prefrence. jiMMy



BETTER WRITE UP... from DTR
There are 3-13mm nuts and 1-10mm bolt.
The 3 nuts are on the flange of the pump, and fairly obvious to see, with the very top and very bottom ones being a tad hard to reach. I loosen off the top and bottom till they turn easily, and the middle one, loosen, then just snug a tad.
The 10mm is at the bottom of and just back of the pump. The bolt actually faces the firewall.
It is on a bracket down there and needs to be loose.
Once that is done, you get a good grip on the pump and push like he$$.
If that don't work get a buddy to reach over the top and pull... if ya got no buddy then get a rubber mallet, and wack the AFC housing at the joint. Don't worry it'll be ok... just don't take a run at it.
You want to open the gap on the two index marks by about 1/8" .
BTW, the index marks are located at the middle of the pump flange and opposite that, on the gear case.
Try to avoid loosening all the other things, you'll need a special socket to get at the majority of fuel lines anyway...
Normally you can get it to move by using one or all of the above methods....

That's what I had already done.
Thanks, I thought there was a more involved process.
