[Archive]

Whats involved in installing a P series pump on a 1st generation truck(91) and is the effort worthwhile.
Thanks

Worthwhile to whom? Lots of work and $. The major parts involved are:
pump
injection lines
pump feed fuel lines
pump drive gear
gear housing

Probably easiest to change injectors so you can use stock lines which have the bigger M14 thread of the late injectors vs. M12 of the first gen.
Removing the housing means pulling the camshaft--a major job--because the gear is pressed onto it. Benefit is that you can check your dowel pin along the way.
This question is almost like asking a physicist "why is a wave".

I guess I'd ask the same question... Why?

If you want more power, there's quite a bit of it available by changing to the infamous (or famous, depending who you ask) big injectors and changing turbo housings and speeding up the governor and re-timing it and all the other "bombing" things you can do. I'm sure you can add up to 120 horsepower more than stock, with pretty good torque numbers, responsiveness and driveability. But, you're looking at seriously stressing the drivetrain capacity of a 1st gen truck, as well.

If it were me, I'd not bother changing pumps. But, this is free advice, and probably worth slightly less than you paid for it #ad

The "easier" way would be to drop in a 2nd gen. post '94 engine in to the 1st gen chassis. Base line costs are at about the level of the Mike Hurd experience.
Your options are numerous for your power upgrades with the killer B engine.
So... this gets the P7100 pump into your truck.
More accurately, your 1st gen truck will handle the power available from this retrofit.
The driveline changes along the years after '93 were for the most part for convience of operation, and to reduce the manufacture and assembly costs. The locking hubs and iron case, gear driven transfer case lost after the '93's can't be replaced by adding a hybrid Dana 80 rear, and calling the truck stronger.
The Getrag 5spd is reliable with upped power levels, and the clutch will withstand good sense application of the power.
Back to the choices:
The overall task is doable, can you drop the pump into the truck? yes.
Can you retrofit a 2nd gen. motor with the "P" into a 1st gen. yes.
All it takes is time and money.
Is the 1st gen truck in good enough condition to justify the work? You'll decide.
Having owned a '92 that made power, and was a DAILY DRIVER, and now a '98 that does the SAME, here was a few comments and some thoughts.

Thanks for the help, as always I am amazed at the wealth of information and experience that is so readily available here at TDR, what a great group to be part of.
Thanks Again
