    I need to replace my fuel lines from the tank to the pump and I was wondering what you guys are using on your rigs. Stock type pre-bent fuel lines or high performance upgraded lines? Just curious if its worth the extra money.

    Also I saw someone say they had 33's without a lift - will they really fit?????

    I have 33X12.50 BFG A/Ts on my truck now with no lift, and they fit fine. I have not twisted it up to see if I can make them rub, but it is likely they would. Plenty mucho clearance for on road or light wheeling though.

    The stock 3/8 hard lines is plenty unless your running some huge 700h/p beast of an eng. then I'd go larger.I have a mild 350 with TPI and I reused the stock fuel lines.
    I also have 33's on my stock suspended 71.No rubbing what so ever.I went 4x4ing for the 1st time at Blazer-Fest this year and didn't rub once,had it pretty flexed out too.At least as flexed out as you can go with stock suspension.

    33's will fit with no lift but they will rub as soon as you take it off road or turn into 7-11. You need at least 2.5" suspension lift to make 'em work right.
