Hey all,

I'm new to the DI world. Will be changing out the HPFP and injectors soon. Stock LT1 to LT4.

I have the seal kits and installation tool for the injectors.

Regarding the HPFP - obviously replacing the gasket, bolts and lines. But what about the cam follower? Replace with new? Reuse existing due to being "mated" to original cam?

I haven't seen any problems from reusing the followers. But Ive probably only done about 100 or so high pressure fuel pumps out of all the cars i work on. They really don't fail very often generally.
I reuse the existing hard lines too but it's your call on that one, most of the internet will say replace them.

A good data point. That's 100 more than I've changed. I kinda figured there would be two schools of thought with this. The "replace everything you touch because reasons" group and the practical "been there, done it, leave it alone" group lol
