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?

mainly for heat generated by the exhaust

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?

ehhhhhh.......i'd leave it though there are plenty of cars from the factory that don't have anything. they have plastic tanks 99% of the time though

Alright, it will depend on how well the car cooperates.

you dont need that ****. whats the worst that could happen to a tank of gas...


fool.

Have you seen it? Its a flimsy ass sheet of metal... and my gas tank is metal, unlike your plastic POS.

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

even a flimsy piece of metal will drop the temp significantly

Leave it, its there for a reason.

X2. Leave it.

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

Well that is the least of my worries at the moment. Friggen car.

take it out, your exhaust dumps under the car, my old 96 ran without it for like a year and a half

:lol: right in front of the tank basically. its definitely all getting trapped in that pocket too

its in front of the rear, the tank is behind the rear... he'll be fine

edit: i dont have it in my current car either come to think of it. my exhaust also dumps before the rear axle

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.

heat will also go around the sheild and still be on the tank, just leave it off since you change your FP so often lol

:rofl:

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.

only way to find out is to stick a thermometer in there!

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.

Yea, no need to get worked up guys, LOL, the shields are going back on next chance I get.

And AC is over rated Bill. ;)
