Replacing fuel injection pump

How hard is this? What parts am I going to need? Any special tools etc? Anyone know where I can find a write-up on this? Is it even worth me doing it versus having someone else do it?

Any help would be awesome!!!

Thanks for anything,

Geoff

It's about an 8 hour job for an experienced tech. In my professional opinion, I would have someone experienced do it if you have any doubts. Why are you replacing it?

Its not hard, took me 7hrs and it was my first time. You wont need anything as far as special tools that are too uncommon. IMO I'd rather spend the money on special tools that I could keep rather than pay 8hrs labor. You'll need basic tools other than a spanner wrench of some sort for the fan clutch pulley, fuel line disconnect tool, and a 3 prong puller of some sort to take the gear off of the pump once you get it out or you could take it to a shop to have it done real quick.

If you need any help you can just PM me and I'd be glad to help you out.

You're right, it can be done faster, I'm just sayin 8 hrs is what most shops will charge. It all depends on if you have the time and basic know-how to do it. If you feel you can handle it then by all means dig in. I too can help answer Q's if you have em. It's not really a hard job, just a lot of stuff to take off to get to it.

It has a larger stroke volume so it is capable of putting out more fuel, you'll need custom tuning for idle because of the LBZ regulator unless you stick with an LB7 regulator and use the LBZ pump. I used EFI live to tune it so that it would idle correctly. Price was the same and externally the pump appears the same other than the regulator with uses the same plug in.

I can do one in under 3 hours. Disconnect the batterys and start tearing her down. Its not that bad just nuts and bolts. Just keep groups of bolts together when taking it apart.
