timing

[funnyman06]

So im trying to advance my timing since im running WMO now, it seems to run a lot more retarded now, but i cant seem to figure out how to loosen all 3 of the nuts holding the pump in place. How do you guys get to the two on the bottom?

Also what do you guys use to rotate the pump? I dont seem to have any tool that can grab the square and clear the fuel line coming out of the top of the IP. How do you guys do it?

OTC makes a nice special wrench just for the pump on these things. I bought one off my snap on truck for around $85, you can buy it from 1-800 ROTUNDA as well .
barring wanting to drop large amounts of cash, an offset open 9/16 obstruction wrench will do the trick.

As far as turning the pump, I've never found the mythical wrench spot on my pump, , so I just carefully take the big oil filter pliers and grab around the outside of the housing and twist

I got mine with just a regular 9/16 open/boxed end combo wrench, took some patience with the bolt on the passenger side with the harness and all getting in the way, but tis definitely doable. the driver-side bolt is an easy access, shouldn't be having no problems getting to it with anything smaller than a crescent wrench. The "mystical wrench spot" is actually kinda-sorta like a tab sticking out on the front face of the pump, tis a bit odd in shape and just as thick as a regular 3/4" wrench is, but it works well.

how about the fuel line coming off the top of the IP? i have a hard line and it crosses in front of the tab. is that pipe easy to just remove and reattach when im done?

I just took my box wrench and grind it down a little bit to make it thinner and it worked great.

Yea just buy a cheap 9/16" wrench and grind down the box until it will fit.

Here's the boss on the front of the pump for adjustment...

Yes, that's it, exactly what SUV7734 posted, I was actually looking for that pic last night as it helped me when advancing mu pump, but I couldn't find it.

It's right here on my camera's memory card...
Hope it helps

Remember, it doesn't move infinitely. My pump on the Moosestang is up against the end of travel in the slots. So... I know new pump time will be near. Yes, WMO is definitely not a performance fuel.

'Cepin they don't all have the mythical pump boss.
I've got three pumps around here and none of them have it. all are later 7.3 pumps

Here's mine:

I can't recal seeing many with that boss either.
