First off thanks for looking any advice is welcomed and appreciated, I bought a used (obviously) mp112 for my 02 Silverado 4.8 I was told it came off a 05 Escalade I ordered a dbc bracket,solid isolator and return fuel block three weeks ago but it looks like the hold up is the return fuel Block, maybe they don’t make parts for it anymore. Want to know if there are any other ways around this with my truck beeing return fuel system? Bare with me my mechanical skills/knowledge are average at best but I have been lurking around here and installed my 4/6 drop kit, water and fuels pumps myself, also has anyone installed a lsa kit from boost district on a 99-02?

 

You might can use one of the Corvette fuel filters to convert your return style fuel lines to the mp112's return less style fuel block. You will have to adjust your tune for the different fuel pressure though. I believe the Corvette filter pressure runs around 60psi.

 

If you can't find one of their return style reg blocks, then just get a normal Aermotive style reg and plumb it in to the non-return block. That way you can boost ref it like the factory reg would have been. I wouldn't run the vett reg because i don't believe there is a way to boost ref it.

Also, get a hold of Brain at Superchargers Online. He will be your best source for that fuel reg block. He used to work at Magnacharger and know how to get all those parts.
