AirDog Draw Straw installation You will need a 15mm socket and 1/2 ratchet for the bands on the tank. You'll also need a flat blade screwdriver, hammer, floor jack, and a ratchet strap. The way I remove the fuel tank is to place the jack under the tank just to support the weight. Then wrap a ratchet strap around the fuel tank and hook it to the jack pivot pin. Tighten the strap lightly not enough to crush the tank. You need to take a screwdriver and hammer and lightly tap on the sender ring

ASD Relay Controlled Lift Pump If the ECM is no longer powering the electric lift pump and you’re using a manual switch wired directly to the fuel pump relay for control there is a danger of the fuel pump feeding a fire in the event of an accident even if the engine stalls. The automatic shutdown relay is an alternative that will turn the fuel lift pump off if the engine stops and still be able to prime the VP44 if needed. The automatic shutdown relay (ASD) in the power distri

My very first step was to install the draw straw. To do so, either the bed has to be lifted off of the truck, or the fuel tank has to be removed; I chose to remove the fuel tank.

Custom AirDog 150 Install Doing a custom AirDog install I think the hardest thing that people struggle with is getting the draw straw installed properly in the proper place. First of the draw straw should not be installed in the sender basket. The reason is the return fuel from the rear of the head is heated by the heat of the head and that will be the first fuel you going to pump back to the VP44. We all know that you want cool fuel for the VP44 this is a bad idea. Second, your draw straw

Just putting an article together to document my experience with installing my Drawstraw 5 with a retrofitted in tank lift pump already installed.

He's a great help and I couldn't of completed this install without his guidance. So to start you are going to have to drop your tank. Now, having more then one person will certainly

This article covers the Timing tables in the ECM that control what timing is at a given point in time. It is meant to help people understand why timing does what it does, and why MPG falls off so fast as MPH increases beyond ~55 mph. It also helps show why mpg is non existent with a truck with 4.10 rear end. For the sake of the article we are only going to look at 3 timing tables, there are more, but they dont really apply all the time. Also keep in mind I tried to make the x ax

Edge Comp Settings From what I understand when your setting you power levels you got the main number (1-5) and the sub level (1-5). To set the sub-level press the power switch and hold for a few seconds and release. The LED bars will be flashing rapidly. Now you can adjust the sub-level. The main number controls the maximum fuel rate and maximum timing advancement. This it the amount of total fuel at WOT that will be used. Higher the numbe

Excessive Cranking Fuel Pressure / Difficult Starting Hot The hard starting problem is caused by a Bosch VP44 injection pump with a damaged diaphragm internally. A torn diaphragm is typically caused from a Bosch VP44 injection pump that was operated at below 10 PSI for an extended period of time. So technically you should replace the Bosch VP44 injection pump to repair the damaged diaphragm but most rig up an oil pressure switch or a starter delay relay.

The subject matter has been discussed for years and all diesel enthusiasts/owners know how important it is to maintain proper levels of fuel pressure via the "transfer pump" or Lift Pump for reliable operation. There are many requirements that each owner/operator may wish to achieve in replacing the OE Carter or perhaps making an aftermarket selection. Notably, most have had the rude awakening of a failed VP44 following the failure of the Lift Pump in a too late scenario. The cost of a VP44 com
