question on injections pumps.

[84cucv1ton]

i found brand new db2 pumps for these trucks. i know a rebuilt one with the newer/updated parts is 250. his price is 180 each. i looked at a bunch of them. i could not find a date.

price seems fair. just want to make sure there not from the 80s or it dosent really matter??

thanks

Price is good, will he back up the pump?

 

[84cucv1ton]

didnt think to ask that. i will call him. i just want to make sure they have the newer internals.

and more importantly...can I get one?

Just make sure they are the high output for the Military spec 6.2L and complete IP.

and more importantly...can I get one?

We could split shipping and I can get it from you if there are two available.

Did I ever tell you that you're like a brother to me?

If you have a turbo I would get a mechanical pump off a 93 diesel.

Get part numbers to confirm. DB2829-4267 and DB2829-4386 are for 84-85 CUCV. DB2829-4520 and DB2829-4521 are for 86-87 CUCV. All have hardened parts. I also have a very interesting PDF dealing with issues observed running aviation fuel through them.

 

[watkinssr]

so what happens if you run a DB2829-4520 or DB2829-4521 on an 85?

 

[Recovry4x4]

Not much. Most of the DB2 pumps are real similar. Mixing up pumps is more of a problem on the DS-4 pumps from the 94 and up 6.5 GM pickups. Just about any DB2 will work unless its a 28V unit from a HMMWV and even it can be made to work if you swap solenoids.

I just want one that will make my truck go down the road...old, new, my cucv is broke and so am I.

Could I get a copy of that PDF ?

 

[watkinssr]

Sounds like a good one for the faq thread. One of my friends in the Navy said they fed them aviation fuel all the time, and were always getting yelled at for it.

 

[acmunro]

It was more of a problem for the 85 and older trucks. The IP didn't like it.

 

[84cucv1ton]

thanks for the part number.

 

[84cucv1ton]

i think a 93 pump would be a db4? they guy i was talking with a bout rebulding my pump said there really is no reason to go for one. i do have banks and 6.5 turbo kits. he said the db2 is fine. no real gain from a db4. seem to caot a good bit more too

 

[Recovry4x4]

Here is the part number for the 93 pump. DB2831-4911
Attached is the PDF on pump wear with Jet-A

 

[watkinssr]

So did the guy have more of them?
