Shielding
Round two of fuel pump install tomorrow night.
Was wondering if the shields around the tank are for heat shielding or for protecting the tank from debris?

Ok, I was thinking of just leaving it off and stashing it in case I ever do throw a catback on it again, bad idea?

My **** is super high performance polymer. Your gas tank is metal because they ran out of ballast stones.

That flimsy piece of metal creates an air gap which acts as insulation. OE does not put stuff like that in for no reason.

i know what you are saying but just think if you are stopped at a light idling at 1k, heat is gunna go up. up into the tank area. just stating physics here.

I doubt exhaust gases will be able to significantly change the temperature of 10 gallons of gas in the time spent idling at a light.

I do know a lot of guys with EFI setups on Power Tour a few years ago were having problems with vapor lock after a few hours of driving. The fuel in the lines was getting heated along its path and and the hotter fuel returning to the tank heated the gas in the tank and causing vapor lock issues. So maybe GM had a reason to go to dead-headed systems.
So my point it maybe professional engineers know more than the average guy does. But then again I'm not smarter than a GM engineer like you folks are.

Well, my rebuke to that one...
Ever run LTs on a 4th gen? Yea... if you are worried about this, don't look at a 4th gen driver side LT.... fuel lines run right over the collector/Y pipe.
But, yea, the shields will go back on next weekend or at least before the Circus Ole meet, so no need to worry about your car being blown up in a 4th gen fire ball.

If something is on the car, chances are there is a reason GM put it there. Unless you are running a secondary (non daily) car in different operating conditions than a daily driver you should put extra thought in removing something before you do. Why dick around with something when you have no legit reason to dump it? Anytime you change something you need to be prepared for possible consequences.
Example: I love it when guys rip the A/C out of their rides for what, (rounding up) 10 hp and 100 lbs? That's great, because on the drive back and forth to work and school you need that extra power... LMAO. Half the time the car won't even get above 4000 RPM the whole day, nowhere near the engine's power peak. But in the meantime, you get to sweat all summer.
