HOW do i figure out what modle of pump i have in my truck i have looked and cannot see a number or a tag the only tag i found was green and has no numbers or letters on it all help is appriceated

Stanadyne tag on rear face, towards intake manifold.

Green tag indicates upgrades installed - ceramic rollers, ESO, Optic Sensor, etc.

 

[jifaire]

Small mirror, flashlight and/or digital camera.

Either that or pulll off the intake and climb up there to eyeball the tag...

From the truck VIN GM can tell you exactly what pump the truck had installed when built .If replaced under 11/120 warranty ,or cutomer pay , accurate info may not be available. It does not cost you at GM for there info on your truck.

You have a 94 F engine. If computer is correct for that year F engine, you have a 5068 pump. That pump is unique to 94 F engine.

You have to be careful as there was a re-flash available to allow the use of the 5288 (and higher) pumps. I just found my truck to have a 5288 pump the other day (and I THINK that I am happy about that...?)...

Ok another question now i am looking at a chip from kennedy and he thinks i should think about upgrading my pump to a newer model cause i have the odd pump 5068 i am not having anyproblems with this truck it runs good and starts good so is this something i should think about or just get the chip with what i have thanks for the info in advance

there are some places that sell those 5068 pumps with modifications that put out much more fuel than any of the other ip's iirc it was like 93mm as opposed to 84mm or somthing like that. if it works good i say leave it on but dont ever scrap it. with some mods it could be quite useful Rigger has one on his truck

At 200kmi you should seriously consider some passed due maintenance, including new IP, timing chainset, injectors, lift pump, OPS, and HO watepump with '97 cooling upgrades.

Opt for the 5521 IP with eprom if you go that route - your 5068 is fairly valuable, as they're becoming scarce, so you might advertise it on e-bay.

THANKS ALL i started going through all the reciptes that came with the truck and @ 160k it says the injectors were replaced timing chain and gears, head gaskets pmd relocated to top of manifold and the ip gone through so it is my thought that i should be okay i'm glad i found these thought i lost them when i moved thanks again
