I accidentally posted this in the wrong thread earlier so here we go again:
Well, despite spending a very exciting weekend at my 8 year old daughter's soccer jamboree, I was able to rework my fuel line and now I have a much bigger space between the exhaust and the fuel line. I cut about 4" from the fuel line and rerouted things. The fuel flow transducer is slightly off of horizontal and I only have about 4" of straight line coming out of it and less than that going into it. I think fire safety (or vapor lock avoidance) is more important than dead nuts accuracy of the fuel flow. From what I've read, it seems that I most likely won't lose much in the way of accuracy anyway. Besides, I also have what are advertised as very accurate capacitance fuel senders and of course there is the time tested digital timer for estimating fuel consumption. Here is how it looks now:
From the bare exhaust pipe (no shield) to the bare fuel line (no fire sleeve) the closest I get now is about 1 5/8" and this is to the tailpipe. I reasoned that it's best to maximize the distance from the portion of the pipe at the cylinder. My line is over two inches away from this area.
I bought the $11 heat sheild from Van's. You can see it on the left but now that I've rerouted everything, it doesn't do a heck of a lot. Then, using Van's design as a guide, I made my own out of a piece of galvanized sheet but I made it much longer. I put it at the closest point and you can see it at the lower center of the picture.
Any opinions or suggestions?
By the way, my daughter's team, the Thundercats, came in second to the dreaded Soccer Divas. It was a fun weekend!
