CP-e HPFP vs internals
 

Why is it that everyone i see has internals either KMD or AT and not the CP-e HPFP?

Because all cp-e does is take an oem mazda pump, and install apr internals in it.

The separate internals are much cheaper, and it is not hard to do the install.

AH! oh ok awesome, thanks! So there is no fuel difference between the internals and the CP-e one?

Nope, and as far as i know most peoples internals are just fine if they are installed properly. However i had a buddy with a GTI do his internals and they seized which blew out his camshaft. Would have been $1500 had he not been tight with the service manager and got it under warranty. For that reason i bought the CP-E pump just for that little piece of mind, plus that pump comes broken in and ready to go, when you install internals you must break them in. Not saying the CP-E pump is any better just that you need to be careful when doing just the internals. Now we did my buddies internals shit probably 8-9 months ago and his car still runs great so i guess its just whatever you feel like running you know.

Wow, only 2343560 of these thread now.

I swear we have a fuel pump thread even.

We do, we do!
