HPFP Part Number
Doing a whipple install soon and want to do the pump and injectors at the same time.
Anyone have the LT4 HPFP, LT4 injectors and associated replacement fuel line part numbers? Any suggestions for the install of these items? I am aware the fuel lines are a 1 time use item, and that I need to properly index the cam to install the HPFP. Anything else worth mentioning? Thank you! |

Jannetty sold me the following, LT-4 HPFP, LT-4 injectors and ZL1 fuel pump assembly.
You'll need a tune for the fuel upgrades as well. |

Sure would be nice to get a part number for the LT4 injectors and in tank pump assembly. I notice different part numbers and options. Parts numbers.....not vendors...

There was not any part numbers on the 2 that I got. unfortunately the first one I got the connector for the solenoid was broken, so I had to exchange it. My stuff came from Pace Performance. This is the part number they list for the LT4 HPFP: 12688607.

I'm sorry I didn't say it correctly, I'm looking for an upgrade to the GM HPFP not just a GM LT4 HPFP. I can't seem to find anything better then a ZL1 fuel pump. My googleing is not getting me what I'm looking for. |

AC Delco part# is HPM1036 - use this as it's the same part but usually priced cheaper
Buy from RockAuto with a coupon code for deals Seems like lots of vendors want $130-1500 for a LT4 HPFP and Injectors - I got mine from RockAuto with the coupon code for like $1070 shipped. I think they've raised prices since, but you get the idea.
