I have a 2008 Aspen with the 5.7 hemi. I had been having Evap codes and believed it to be the top cap of the fuel pump cracking, allowing pressure leaks. I had purchased a fuel pump & lock ring in preparation for the job. Before I could get to the process, the truck died and I had to get it towed home. Based on its starving & stumbling action prior to stopping running, I figured a failed fuel pump. I checked that the fuel pump relay was engaging and even swapped with another relay of the part# to confirm it wasn't bad contacts. I did not hear the pump run. I checked for pressure at the rail and there was none.

My dilemma, I need to get the truck to the garage and into the bay to get it on the lift. I looked at simply changing it on the ground but I cannot move it on to ramps for additional clearance and I cannot get under the truck as-is with enough space to get my body in to get to fasteners. I am also not sure there would be clearance to pull the tank out once dropped. It currently sits on gravel and I do not have jacks with a enough lift height to gain any material increase with jack stands. I tried smacking the tank with a rubber mallet in what little access I had, which wasn't much, in order to try to get the pump to start up again. No joy.

I am thinking about a temporary fuel supply, that I can place directly to the fuel rail, for a short start and run maneuver to get it to my lift bay. I am a one man DIY guy without access to other bodies or equipment to push/pull the Aspen around the property. Has anybody rigged up something temporary to achieve this before? My thought was to use the metal injector cleaner canister used for 'no dismantle' injector cleaning ( I have one). It has an air supply connection and regulator to get the pressure correct (which by the way, what is the correct fuel pressure for the Aspen?) Plan was to fill the metal tank with gas, connect to the Shrader valve on the fuel rail, bring the pressure up to spec and try to start the truck for the short move. I figure there should be enough fuel to run for maybe +/-5 minutes.

From a Google search, I did find a tool for just this purpose and it was around $400. I really don't see much difference between it and a fuel cleaner canister.

Any input would be appreciated.

 

smack the fuel tank where the pump is at on the bottom this will jar the pump enough to likely get it stared for a few min to move it.

 

I have used this trick on an older Chevy Pick-up before.

I did try smacking the tank with a rubber mallet in what little access I had, which wasn't much. I cannot fit far enough under to access all the skid shield bolts and remove the shield and thus cannot get a good clear wack at the tank. My chances of losing 40lbs and fitting, seemed less likely than an alternate fuel source LOL
