revisiting fuel lines (carb to pump)
I was involved with some discussions a couple years back, one of which HFR mentioned "The Right Stuff" (TRS);
At the time I had a fuel line on order which was sourced from In Line Tube (ILT). After it arrived, I was less than pleased with the ILT line, it needed A LOT more coaxing to make it fit that I would have hoped. I decided after that to place an order with TRS for full fuel and brake lines for my car, and while I was at it, I decided to add to the order three fuel pump to carb lines: 1) 70 RAIII; #FPC7021 2) '70 L78; #FPC7020 3) '71-72 HO & 4bbl; #FPC7220 Covid prevented me from getting my package to my place till this spring (I had it shipped to my cousin's in Oregon), and until this afternoon my box remained sealed in my garage loft. Now, I have the following engines sitting in my garage, on stands, completly mocked up; 1970 YZ (RAIII) 1970 WT (400/4bbl) 1972 WS (A-body; 4000/4bbl & 3spd) I started with the RAIII fuel line, and my oh my what a difference from the ILT line - I was quite impressed. I then went to the engine which is correct for my car; at first glance I figured that something was really wrong, because it looked so short - then I remebered that this line went on the drivers side of hte thermostat housing; I lossened and moved the rear alternator bracket out of the way, and connected it lightly to the carb - and it looked good - the curves matched everything on the engine nicely... BUT... the bend seemed quite short for the fuel pump... And the angle looked wrong. So I pulled the fuel pump off (a replacement that I ran in my car since the late 1990's), and replaced it with another that is the absolute correct one. The line still looked wrong. I started tweaking the line, then stopped when I noticed I caused a small kink. I then moved onto the 1972 engine; Again absolutely perfect. I went back to the 70-400/4bbl line and tried making it work again - but only made matters worse. It occurred to me that it's as though this line was made for a full size car which may not have had a deep fuel pump. Have many of you bought from TRS before? I figure I'm up crap-creek because I bent it, but I am wondering if by chance these are bent by a human, or if something is in the mix where the bottom bends for the fuel pump may have been done too high up... Thoughts?
