Alright so i have done a lot of searching and it has been awhile since i have done some things with my fuel system. I am swapping engines and need some new parts.

Now my question is what do i need to retain for my fuel setup? I currently have 1680cc Top feed secondary injectors (kgparts rail) and 850cc Side feed primary with a milled stock primary rail.

What i already have
deleted FPD
SX FPR
LIM spacers for 1680
Supra TT pump
rewired for more voltage
resisters for 1680's

Now my question, With the 1680cc injectors i install the Lim spacers and keep the diffuser, or do i toss it? Do i need anything else for the secondary rail at all going into the block?

Next the primary injectors. Install the spacer/shim for the primary rail to sit onto the block. do i need the diffuser for the primary at all or toss that? Than just use the 850 injector oring to seal the injectors in with the block.

Am i missing anything at all?

Thanks Jake

 

Anyone? Im just trying to find out if i need the diffuser in for the secondary and primary?

Im glad you were able to find that. It was not very helpful sorry.

He did not mention using the Secondary with a diffuser at all or insulator. ??

He did however outline a topfeed primary. unfortunately i am using the stock primary rail with 850's in them.

Now, does anyone have any information that might be of some help at all?

 

Kg parts has a installation video That pretty much tell everything! Just go to there site.

 

I cut the legs off the diffusers for the sec when using big injectors .I am running 850/1680s .

 

Are you using side feed or top feed 850 primary injectors?

thanks for the info
