I am doing a TPI swap on my 87 Camaro.
I have a carbed engine now but have ordered TPI setup with wiring harness and ECM and PROM.

This setup is from a MAF TPI from 1989 Camaro IROC

And now my question...Do I need to change the fuel lines?..I know I need to change my fuel pump to a bigger one, but I have also heard something about changing my fuel lines.

Do I need to change only the rubber hoses going from pump to steel lines?..Or do I have to change the Steel lines all the way from the tank to the engine. Main line and return line??...

 

Are there really no one that could answer me my questions?..I am sorry if i am hard to understand because me english is not very good at all.

I have a 87 Camaro with a 305engine and a CCC-controlled carb.
I have now bought a complete TPI kit.

Do I need to change my Fuel lines all the way from tank to engine?..Or just the rubber hoses?...Please answer anybody

 

u shouldnt have to change fuel hoses maybe a larger fuel pump that would push more fuel other than that u should be ok

 

Really??...Are you sure I don't need to change hoses or lines when i am converting from Carb to TPI?...Because when I search for fuel lines at Ebay. I find one type that is made for Injection and one type that is made for Carb.

 

oh ok well it should just be the lines that connect to the engine then id just go for AN lines

 

Carb should be a single line, but EFI requires a return line, so you need 2 lines.

You should be able to use the same feed line from the tank, but you will need to add a return line. If you go that route, check out the AL fuel lines from Russell - that looks like a good way to go without paying for full braided, and should be safer than rubber.

One way to do it is pick up a fuel tank from an EFI car with an in-tank pump, and then use some factory fuel lines, which I believe is plastic. Check out your fuel tank, it may have both a feed and return provision since EFI was available in 87 as well. Where is your fuel pump now? In-tank? Or is it on the motor?

I will be doing this exact swap in my CMC race car soon. I have not decided which path I will go down - the car is an 83, so no EFI was available. I probably would need to add a return line to the tank, which means pulling it out and draining it for the welding - which is always scary with fuel involved... So it may be easier for me to replace the tank with one from an EFI car. I'm not sure which way I will go yet - I need to take a look at how my tank is set up.

 

My fuel pump is in-tank now. So I need to drop my tank anyway to change the pump in to a TPI pump. I am not sure about the fuel lines though. Mayby I just have 1 fuel line, but I think I have 2. Anyway I think I also have to change the main fuel line because TPI engines have the FUEL filter in the middle of the line or in the beginning of the tank if i'm not wrong. Carbed engines have the fuel filter on the Carb so that I would have to change.

 

I noticed from another post that you have gotten a harness from a 1988 IROC to go with your tpi from an 89. Can you get the fuel lines back to the tank from the same 1988 car? You would be better off to run steel lines to and from the tank with as little rubber line as possible.

 

You definately need to have either steel or braided lines going from the tank to the TPI set up, the pressure is about 45 psi I believe, but the return doesn't need to be as heavy. BUT, if you can get your hands on factory fuel lines it will help you tremendously not only with fitting correctly, but being able to order stock fuel filters, hooking them up et al. If you don't, and need to find a different fuel filter, make certain it is rated for high psi or you will clog your system.
