cockerstar Posted October 2, 2017 Share Posted October 2, 2017 (edited) I'm in the process of running -6 (3/8") Cunifer hardlines for a new feed and return and was intending to run them in the stock location, but that's going to involve dropping the transmission at a minimum. I'm working alone right now on jack stands, and have a chronically injured wrist, so dropping the trans really doesn't sound like fun. Has anyone ran fuel lines somewhere other than the non-stock location? I was considering running them next to the frame rails inside some side of conduit, maybe framing channel. The frame rail would still be the lowest point on the car would, but I'm concerned about road debris getting kicked up and damaging the lines, hence the conduit. Framing channel / Unistrut came to mind so that any moisture could drain out. Rain is the norm in the Pacific Northwest. My other thought was running them inside the cabin in a solid conduit, but I'm still concerned about shearing at the bulkheads in the event of a serious wreck. I know several OEMs run fuel lines inside the passenger compartment, but my gut is telling me that fuel inside isn't wise. I was browsing tech requirements from several different racing bodies as a guideline and the acceptability seems to be mixed. Jeromio did an excellent job running them inside of a new frame rail here: Any advice? Edited October 2, 2017 by cockerstar Quote Link to comment Share on other sites More sharing options...
wheee! Posted October 2, 2017 Share Posted October 2, 2017 Not sure which S30 you have, but you could run them 280 style along the frame rail... Quote Link to comment Share on other sites More sharing options...
cockerstar Posted October 2, 2017 Author Share Posted October 2, 2017 I guess I'm completely overthinking this! I only have 240Zs and haven't worked on the later chassis. That's exactly where I was considering running them, but was concerned about them being exposed to road debris. Thats the factory location for 280Zs? Thanks for sharing such excellent photos!

HuD 91gt Posted October 18, 2017 Share Posted October 18, 2017 Makes me feel like an idiot for running my recent 3/8" lines in the stock 240z location. Didn't end up taking the tranny out (Would have been way easier), but the whole rear suspension was gone. Ugh. Quote Link to comment Share on other sites More sharing options...
Chickenman Posted October 18, 2017 Share Posted October 18, 2017 (edited) Wheee...my Lord that is a beautiful looking Chassis. Well done sir Edited October 18, 2017 by Chickenman Quote Link to comment Share on other sites More sharing options...
madkaw Posted October 18, 2017 Share Posted October 18, 2017 Well I ran 3/8” supply in stock location with engine and trans installed . Bitch? Yes! i used the fuel tank vent line for return - it’s big enough Quote Link to comment Share on other sites More sharing options...
jhm Posted October 18, 2017 Share Posted October 18, 2017 My late-model 260Z also had the fuel lines running along the passenger frame rail. Car was lowered, raced often, and never had an issue with debris damage to the lines. If you really want to go the extra mile, you could sheath the lines with clear or black hose for extra protection in the most vulnerable areas.
