4126 LD -Light Duty Pump

Out of a Parts truck I had for the Firewall fuel lines for the 1982 Only Spin-Off Fuel Filter, The motor has a Model 4126 IP Pump... The tag shows it's been rebuilt in 99.

I certainly don't ever see any Model 4126 Pumps out there being sold so I'd assume they are a bit Uncommon nowadays... I plan to keep it for my Other Light Duty K10 truck (As a spare) from the pump that's on it now I believe model 4041 (Which all i can find online say's Olds 5.7L Diesel Pump Pre-1980) But it's still DB-2829 So It works with any 6.2L I'm told.

My question is, What's the 4126 Pump worth?

That model is so old. Maybe $25 as a core. Lots of updates have made that model really undesirable. The 5.7 pump doesn't fit the 6.2 and vice a versa , will not bolt up.

Which one are you talking about?
The pump is on my engine right now and bolted up fine.

*Edit* I see what you mean the front Mounting plate is Round vs the Odd Shaped 6.2L One.

It's a DB2829-4090 just a run of the mill 6.2 pump.
Keep it as a spare, run it till breaks or craps out.
You can turn it up if you need to.

Well too late to keep it as a Spare, Its already been on the engine for a few months now I am going to keep the DB-2829-4126 as a Spare, Along with the Injection Lines, Heads & Crank. That is if those items are not In Horrible shape.

I have a separate Red Block J-Code from my 3/4 Ton truck I'm parting out to keep as a Spare Low-Miles engine.
