Intake/Fuel line ?

Can any of you guys with truck coils and LS1 intakes post pics of how you did the fuel line on the manifold? My fuel line off of the intake is hitting the third coil pack and I can only think of one fix. Also, does anyone know if the walbro intank fuel pump is the same for third and fourth gens? Thanks.

I had originally taken a pipe and put it around the Russell fitting on the fuel rail and just bent the end of the rail upward away from the coil pack. I didn't like how my line looked aimedup towards the hood with a straight Russell fitting so I eventually swapped it for a 90* fitting which kicks the fuel line straight back towards the firewall. I will post a picture for you shortly.

I'm assuming the pumps aren't interchangable but someone else may chime in and say differently.

I just bent the fuel rail line up a little bit. The pumps should be the same but I'm not 100% on that. I used the Walbro for the 3rd gen.

Re: Intake/Fuel line ?

I used the Walbro 255 for a 3rd gen... I guess the reason why I'm thinking a 4th gen won't work in a 3rd gen tank is because the fuel lines and evap system is totally different? I'm not positive though. I guess an easy way to tell is check to see if the part numbers are the same.


Here's my fuel line after I put the 90* fitting on:

Re: Intake/Fuel line ?

I have LS2 coils and they must mount higher than normal truck coils because I had to bend my line completely vertical. I dont like that at all

My walbro came out of a 4th gen sender. They fit. IIRC walbro uses the same PN for both car pumps, just a different install kit

Thanks guys. The coil packs on my engine are the round ones.
