Dear Hummer enthusiasts,


I am a new member, have had my H2 since 2003 and love it. has 228,000 miles and recently the fuel pump went on it. We replaced the Fuel Pump but cannot for the life of me find a new/used Pressure Line for it. GM part# 15203680. Everyone I call they say its Discontinued. Does anyone know if maybe the Tahoe? or Suburban use the same pressure plastic line? Or where can I buy one? Any help would be greatly appreciated! Thank you frustrated in Boston. Please #2 below in illustration.

 

I did a quick google search with your part number and there are several sites that say they are available. It looks like it was the same on H2 and SUT through 2009.

Napa or most professional type auto parts stores have kits to make and build plastic fuel lines for EFI on modern cars. Dorman is one of the companies that makes a kit. I used their kit when I made lines for an LS swap in my '69 GMC.

 

Shout out to "Calif Phil", thank you for your recommendation on the Napa Fuel Kit. It worked perfectly!! I didn't even know they made those. Soaked the line in hot water and then cooled it down and it adhered like glue! I had to buy new straps for the gas tank though. They were rusted and almost broke through. That would have been bad. Anyway I am happy to be driving my H2 with 228,00 miles and still runs like a champ. Thank you again Phil and HUMMERFORUMS! -Marlon

 

I realize this is an older post but wanted to ask you, How difficult was it to remove your tank and could you possibly walk me through the steps? If not, no problem, I will keep searching this topic. Thanks

 

It wasn't too difficult to remove the tank, but make sure you have as little gas as possible. I had less than an 1/8 of a tank. The tank can be lowered by first removing the shield, We removed the two tank straps (4 bolts total) and then the fuel line/pump. disconnecting lines, hoses, and electrical, and lowering, moving backwards as you go. It helps to tilt the rear of the tank down, and once you clear the axle, you can lower the front. We used a floorjack to help with the weight and stability. Draining the fuel is the best but not always possible. The hardest part was the retaining ring, we used a hammer and large screwdriver. Tap gently to set it free. I had help from a buddy who worked at NTB. We were amazed that the tank didn't just fall, the two original straps had completely rusted through. We replaced with two new steel straps. He did most of the work, sorry. Hope this helps. -Marlon

 

Thank you h2hummer5, Every little bit of knowledge helps when someone has not done the task before. I ordered the pump, seal, and ring today. Im going out right after this post to jack the truck up and drain the fuel. There would have to be 3/4 tank right? That's just my luck. Last week I had to replace the ignition switch... oh well. Thanks again
