OK ive got the 2001 tahoe line hooked up as far as the filter and all the way to the tank for the return line now i need to drop the tank and put  the hi pressure pump in  and sending unit out of a 87-91 R truck im waiting on the sending unit to come in and then i need to order the pump the guy doing my harness said he will send it back to me this monday so waiting on that too then i need to hook up the trucks power to the new modded harness and send out the PCM to get all the emssions ,VATS,A/C ,rear o2 sensors, etc removed
im hoping with all the emission removed cats gone and the shorty header for around 305 HP in standard form

hey chris or anyone else thats done an LSX conversion!!! what cable did you use for the throttle body i got one from a k 2500 96 4x4 truck today its seams way too long and where it hooks up  to the pedal looks the same but its longer
the top cable is the 96 K2500
the bottom is the factory 78 c-10 cable
you can see the cable is longer where if hooks to the pedal
but also the cable is a good 18"  longer i need one about 12" longer the factory cable is too short!!

The TBI fuel lines are not rated for that much pressure especially if they are old.  I would change them.
As for throttle cables.  I am using a Lokar.
