Re: LS engine swap info
Yeah I didn't want to use any AN hose (trying to keep it factory looking) so it was easier to just swap the fitting from my old pump to my new pump and use my stock 72 lines. Cost was $0.00

Re: LS engine swap info
is it true that if i am running the truck intake, i do not need the corvette regulator filter unit? I can just run the external fuel pump and a filter to the rail that on the truck intake has a integrated regulator?
|
Re: LS engine swap info
If the fuel rail is the older version, 2003 and older I think, that has the integrated regulator with two ports on the rail (inlet and return), then correct you don't need the Vette filter/regulator.
If it only has one port, then you will need to use the Vette filter/regulator. |
Re: LS engine swap info
should have stated it is a 5.3 out of a 99 gmc 1/2 ton. I have been reading and reading and reading,,,my mind is melting...there is tons of info but i cant just pull it all together ahha.
thanks! |
Re: LS engine swap info
LOL, I understand completely! You are good to go with just a regular filter.

Re: LS engine swap info
i dont want to hijack the thread, i probally should just continue on my project thread but i dont think i will get the hits like on this thread..... so do i just run new lines of my current fuel tank on my 84 to the pump to the filter to the rail and then run the return back to the tank?
|
Re: LS engine swap info
You will need fuel injection rated fuel line, filter, clamps, and of course the fuel pump. Try to use either as much solid line as possible, or stainless braided line. Try to keep FI rated rubber hose to a minimum, as in just connections.
Supply line from the tank, to the filter, then the pump, then to the engine. All 3/8" (-6AN). Return straight from the engine to the tank. 5/16" (-4AN). Do you have two tanks? And if so, do you plan on keeping both operational? |

Re: LS engine swap info
Is the VIN stamped on the block anywhere? I can't seem to find it. I'm tTrying to figure out exactly what year my motor is. It's supposed to be an 06, but I just want to make sure prior to ordering my harness.
|
Re: LS engine swap info
the block year doesnt matter until you get into the 2007 ( GEN IV) year and they changed some sensor locations, If your ordering a harness just tell them if it is DBC or DBW. Correct me if I am wrong but this is what I was told.
|
Re: LS engine swap info
that is the way I understood it. If the motor and PCM came together and you are 100% sure, that information can be pulled from the PCM.

Re: LS engine swap info
In doing some research I was unable to come up with a cure for my return line issue. I have a truck intake with regulator and return. I wanted to switch to the corvette filter with regulator and ditch the return line from the engine but stick with the truck intake because it's tall and I think it fits the engine bay better than the shorter car intake (not to mention the car rails all seem to have the feed pipe pointing to the left instead of back towards the firewall). What I did was replace the left fuel rail with a non-return rail part number 12602113. Then you can toss the return pipe that attaches to the rail and you're left with only the feed pipe. You can also get retainer kit part number 89017378 to replace the one that was originally for both tubes, I plan to just trim the one that was there.

Re: LS engine swap info
Or you can get a different set of fuel rails that does not have said FPR on it from the trucks, I do not have a good pic of it but it accomplished the same thing as mentioned above. Heck, I think I got a spare fuel rail here that does not have a FRP on it.

Re: LS engine swap info
Over on ls1truck, ls1tech, et al, the guys that are building up GenIII's with LS6 and other aftermarket intakes practically give the 04 > truck intakes and rails away.
|
Re: LS engine swap info
If you want to go big, I can ship you a 102mm FAST intake for the truck for $840 and $30 for the intake gaskets if you want them too.

Re: LS engine swap info

Re: LS engine swap info
Is there some way to id year of motor online using the computer/ecm number? I have same prob as guy before, not sure of year of motor and i don't have a transmission yet...(po i bought from said he "thinks" it was from a 2006).
|
Re: LS engine swap info
Theres a 3 digit code (like DCP) that doesn't match the RPO number (LS1, L92, etc)...the dealers Parts dept) don't seem to know what it means... but someone at GM has to.
