I usually pay about $7 a can or $14 a purge. Since you do it once a year it is worth it. Also, when I change the main filter I fill it with 1) Diesel Purge or 2) Diesel Kleen from Standyne or 3) B100 any of those work to clean the injectors.

If you are going to do a purge, do it right. Get a plastic container (an old Diesel Kleen jug works great) and two two foot lengths of fuel hose. Disconnect the inlet side of the fuel lines right before the plastic pre-filter and connect one of your hoses to the filter. Plug the line coming from the fuel tank (a 1/8" drill bit works great for this) Next disconnect the line coming from the fuel return (cigar hose on 616-617s) at the connector on top of the main filter. Attack the other hose to the connector on the filter. Stick the hoses into the jug and pour in 2 cans of DP, reserving about 4 ounces for filling the main fuel filter if you are changing it.. Wedge the jug somewhere will it will not slip out and will not get too hot. I wedge mine into the left front fender area behind the headlights.
Start the car and rev the engine a few times. Once it is running smoothly. take it for a couple spins around the block flooring it a few times. You should see massive clouds of black smoke coming from the tailpipe. 2 cans of DP gives you about 20 minutes of running time so you can get around the block a few times. Remember to take your phillips head screwdriver in case you need to switch back to the fuel tank out on the road!. When you get home look in the jug. You will be amazed at how black the remaining DP is! Remove your rig and reconnect the original hoses - changing the pre-filter at a minimum. I usually change both filters, pouring the DP I reserved earlier into the filter before screwing it on. Having fuel in the filter eliminates having to pump the primer 100 times on the older engines or cranking the crap out of a 603
