So what is the Holder to run? Stock? Billet? This is for a street driven 12v with a 13mm pump. I am building the pump at work and I would like some input on what to do for delivery valve holders. The pump is 180hp pump with 13mm P&B's, 022 d/v's, 5k gsk. The pump will be set around 500-600cc but will be set for more if needed. I will be running 5x18 injectors and either .093 or .120 lines(still need to get lines and bend them up). Are bigger D/v holders needed?

First off you don't need the lines, stock will work just fine. What are your goals with the Truck? You can get 500cc out of a 12mm pump so why Not go that way? If I remember right you need some specialty tools to build a pump, definitely will need a shop to bench an flow.

I heard the same thing about the lines. For a mild 13mm, stock lines are OK, no bigger than .084.

A 13mm pump has a quicker injection rate than a 12mm. So for a given amount of fuel a 13mm should produce more hp and burn cleaner.

If it were more cost effective, I'd be right behind you on this. With stock lines, you will avoid lope, and save money. You should be running responsive, clean, and efficient with how quickly you'll be getting the fuel into the cylinder, and be able to hit you timing mark to get it right at the bowl lip.
 
I'm getting lines because I got my intake milled off and have an intake runner. I Work at an injection/diesel shop, Diesel specialist of Green Bay, we have 4 or 5 benches and all the tooling for almost any injection pump including common rail so the pump will be professionally built, as for a use for the truck I'm building a street/strip truck that I'm shooting for about 800hp with the fuel to make 1000 fuel only.
 
Well for those who got a built 12mm or 13mm pump from an injection shop what is on your pump? billet or stock holders?
 
My 13mm pump from northeast diesel has billet holders. I was told they were necessary, to much restriction there would damage pump. Stock lines and factory Bosch cam.

How many cc's is your pump flowing? And what are you using it for?
 
WhiteKnight has a Darren Morrison built 12mm pump and it came with billet .120 holders on it. He's running .120 lines as well. (Flowed 780cc's)
I have a 180 pump benched by Seth at DPE (before he left) and I run .093 holders and lines. No lope once it's warmed up.
FWIW Seth said I could get another 50cc's out of the pump if I ran stock holders.

You mean and extra 50cc's after swapping out to the .093's?

And is there anything special about the billet DV holders, or is it just the hole out of the top for the injector line? What would be the downside to drilling the stock ones larger if you took care to make all of them the same (say you had access to a pretty accurate lathe)?

Or is there more to it than that?

He said my stockers would flow 50cc's more due to the pump not having to fill a larger void I guess before reaching pop pressure.

My holders just have a bigger hole. WhiteKnights have a bigger hole and also don't run the piece that you put in on top of the spring. ( I forget what it's called right now... Brain fart)

The valve in the holder is there for a reason.

In the thread you posted you mentioned the decrease in flow with the aftermarket holder was more due to people running a factory compression valve and spring... Care to expand on this? Right now I run the .093 holders and lines with the factory springs and valves in the holders. Would I benefit in upgrading and where would I look to get them?

Mine has billet .093 holders. Pump flows just over 900cc with 024 DVs and no plate. I plan on running it around 600cc. I may bump it to 650-700cc at some point. But I'm running stock rods and the block is not filled, so that much fuel is pushing it.
