New Bunk heater issue

[Waterloo]

Pump doesn’t attempt to run or click at all. Then get the red light with 52 code. It’s never worked since I owned the truck and the previous owner never used it. They only idled. Hope you can have a little better luck than I usually get. Good luck!

eBay and or Amazon has all the parts to get your D2 running. There are two fuel filter screens, the one in the little fuel pump is likely clogged up. Then there is another screen in the D2 unit itself that more than likely needs replacing. Here is the repair kit I used, $35, it has the two filters you need. https://amzn.to/3PjPAJK

I would also purchase a new glow plug, you will be in there, replace it. I prefer the Espar OEM parts, https://amzn.to/3hhPOEI

Here is the exhaust and I bought another for the intake side, so two of these flex pipes https://amzn.to/3FmHOKO

This fuel line kit, mainly for the hose clamps, I broke a couple of them when removing the in line fuel pump. https://amzn.to/3FNfm5W

Here is a very good video on everything you will need to know on rebuilding and cleaning of your D2 heater. https://m.youtube.com/watch?v=56HCZ0C0ORk

I rebuilt mine in October, running like a champ!
