I am looking for a good part number for a fuel line. 2007 Chevrolet Silverado 5.3L factory markings of GM 213M type H, on the hose.
I ruined the 90 degree hose connection, which fastens to the fuel pump. Need to replace the hose while changing out the fuel pump.
Thanks for your help.

f you read automotive articles on a regular basis, you’ve no doubt read about the scientific side of brakes many times. They convert kinetic energy, which is the energy of motion, into heat energy through friction between the brake linings and the drum or rotor. Because of this, brakes get hot…real hot…and dissipating the heat is one of the most critical factors affecting brake operation.
So, would you believe that shock absorbers work off the same scientific basis of converting kinetic energy into heat energy? It’s true, and here’s how it works.
Kinetic energy is the energy of motion. The springs on a vehicle support the weight of it and allow the suspension to move. But what would happen if there were no shock absorbers? Every time you hit a bump, the springs would compress then expand, and do this over and over again until they finally settled down.
If you’ve never experienced the sensation, which is something like rocking on a boat, you’ve likely seen it on a car going down the road. The front or rear goes up and down, up and down, literally “bouncing” down the road. It happens, in this case, not due to the lack of shocks, but due to the fact that they are simply worn out, so for all practical purposes, they may as well not exist.
link hidden, please login to view The springs absorb the kinetic energy from hitting a bump, but since springs are considered elastic objects, the energy is turned into potential energy. And, in the case of a spring, or any elastic object, the potential energy is then released, and the energy output equals the energy input. The spring will return to its original shape. At that point, the momentum of the car body creates kinetic energy, which in turn acts on the spring in the opposite direction. As you can see, this is a vicious circle, and we need shock absorbers to control it.
The job of a shock absorber is therefore to control the kinetic and potential energy of a spring by dampening its movement. Shock absorbers are filled with hydraulic oil, separated between two different chambers. Between the two chambers is a piston and valve assembly. (See Figure 1). The piston is connected to a piston rod which moves in and out of the shock as the suspension moves.
Compression is when the piston rod is forced into the shock; rebound is when the piston rod is pulled back out. The key lies in the valving, which restricts the flow of oil between the two chambers. Forcing the oil through these valves creates friction, which in turn creates heat. Yes, shocks do get hot, and now the shock has turned kinetic energy into heat energy.
Changing the size of these valves changes the amount of force it takes for compression or rebound, which ultimately changes the ride characteristics of the vehicle. This is one of the main reasons there’s a difference in feel between a sports car and a luxury car.
The more restrictive the compression and rebound, the less the suspension spring will move, which provides improved handling and stability characteristics, such as those desired on a sports car, but this also results in a firmer ride. Less restrictive compression and rebound allows greater spring movement and a softer ride, but not as good handling characteristics. There’s always a tradeoff.
The comparison between the compression and rebound forces in a shock absorber is the shock ratio. Many standard shocks have a 50/50 ratio, meaning the compression and rebound forces are equal. Unequal forces one way or the other can have a drastic effect on handling, and one of the best examples to demonstrate this is with some old school drag racing tech. In drag racing, it’s important to shift the weight to the rear of the vehicle to increase traction while launching. One of the ways to attain this is by using 90/10 shock absorbers on the front.
What this means is that of the total compression and rebound forces, 90% of the force is required to compress the shock, but only 10% of the force is required to extend the shock. When launching, the front of the car wants to lift as weight shifts to the rear. With a 90/10 shock, the front will unload easily and allow the weight to shift to the rear. Then, since it takes a much greater force to compress the shock, instead of the car coming right back down and bouncing in the front after hitting the track, the shocks will remain extended with the weight shifted rearward, and slowly settle as the car goes down the track.
It often takes a while and a few different adjustments with shock ratio, both front and rear, to get a drag car suspension properly “tuned” in. By the same token, stock vehicles, either performance or luxury, are engineered to find the best of both worlds in handling versus comfort. So, the next time you talk about shocks to your customer, make it fun and talk a little science.

Chase Elliott and the No. 9 link hidden, please login to view team qualified ninth for Sunday’s NASCAR Cup Series race at Kansas Speedway. Elliott finished stage one in 10th and followed that up with an 11th-place result in stage two. The 28-year-old driver lined up fourth for an overtime restart in the final stage, driving to a third-place finish. It was Elliott’s second consecutive top-five result and his fifth top-five in the last six Cup Series races. The 2020 NASCAR Cup Series champion ranks third in the points standings, just 55 markers behind the leader. Chase Elliott started ninth in Sunday’s rain-delayed NASCAR Cup Series race at Kansas Speedway and was scored in the 14th position on lap 10 when he reported that his No. 9 NAPA Auto Parts Chevrolet Camaro ZL1 was tight. As the run went on, he radioed that his Chevy’s handling was coming to him. Elliott was in 15th when green-flag pit stops started near lap 30. Crew chief Alan Gustafson called the driver of the No. 9 to pit road on lap 33 for four tires, fuel and an air-pressure adjustment. He was back inside the top 15 once the field cycled through pit stops. By lap 62, he found his way to 10th where he remained to end stage one on lap 80.
After pitting for four tires and fuel during the stage break, Elliott took the green flag for stage two from the ninth position on lap 89. A chaotic restart shuffled the 28-year-old driver back to 15th, but as the run went on, he made up ground and climbed to 12th by lap 113. As green-flag pit stops were drawing near, Gustafson asked Elliott for feedback on the NAPA Chevrolet. After receiving positive comments from his driver, Gustafson radioed for Elliott to visit pit road on lap 119 for four tires, fuel and an air-pressure adjustment. Once the pit cycle was complete, Elliott was back up to 12th and continued to close in on the cars ahead of him. By lap 143, he re-entered the top 10. He battled hard to remain in the 10th position, but another car just barely beat him to the line to finish stage two, relegating Elliott to 11th.
Under the stage-ending caution, Elliott reported that he really liked his NAPA Chevy’s balance. He brought the No. 9 Chevrolet to the attention of his pit crew for fuel and four fresh tires. A fast stop gained Elliott three spots on pit road. He started the final stage from the eighth position on lap 173. The early portion of the stage was plagued with cautions, with Elliott and the No. 9 team opting not to pit during the first few yellow flags. When the caution came out again on lap 198, Elliott pitted from the ninth position for four tires and fuel. Varying pit strategies put Elliott in the 20th position as the field lined up for the choose cone. He took the outside lane for the restart on lap 205 and powered his way back inside the top 15 on lap 208. Elliott continued his climb forward, reaching 10th less than 10 laps later. As the long green-flag run went on, he gained two more positions. Elliott was in eighth after a caution came out on lap 261, which sent the race into overtime. When pit road opened, Gustafson called Elliott in for right-side tires and fuel. Elliott was the fourth car off pit road, with the top nine cars all taking two tires. The 2020 Cup Series champion lined up on the outside of the second row for the overtime restart. He battled intensely in the final two laps to take the checkered flag in the third position.
The finish was Elliott’s second consecutive top-five finish and his fifth top-five in the last six Cup Series races. The Hendrick Motorsports driver leaves Kansas Speedway third in the Cup Series points standings, just 55 markers behind the leader.
