 Racor PFF50216 Coalescer Fuel Filter For GM Duramax Diesel Engines 2001-Present 

The newest fuel filter for the 2001-Present Duramax Engines is the Racor PFF50216. Racor makes the AC/Delco filter (TP3012) for GM but you can get it here for much cheaper than any dealer will sell it to you. Most GM/Chevy dealers are selling the same filter packaged as the AC/Delco TP3012 for 64.00 or more each.  Even Rock Auto Discount Auto Parts online sells them for 48.79. We sell them for 38.99. There are vendors that sell them for 27.95 each but then rape you on shipping. We here at MadJack Diesel are consistant across the board. Buy 3 filters pay 35.66 each.

Buy 2 and pay 37.99 each, Buy 3 or more pay 35.66 each. Just use the drop down menu to add the amount of filters beyond the first filter and the price will automatically be adjusted. As always any orders over 150.00 is free shipping to the lower 48 US States.


The Problem   

Non-OEM tested "will-fit" replacement fuel filter reproductions do not offer proven real world engine protection. "Will-fit" fuel filters using only paper pleats have lower performance in low quality and biodiesel fuels.

The Solution

Racor’s genuine high-efficiency long-life "depth coalescing media" replacement fuel filter. The PFF50216 has been tested to OEM standards for life, efficiency, water removal, and is now standard and backward compatible on all GM Duramax engine applications. The coalescing filter system inside has up to twice the life and improved water removal in all blends and types of diesel fuel when compared to other paper media filters.

How It Works

Racor’s PFF50216 is a genuine direct replacement coalescing fuel filter for the GM Duramax engine.

The Racor coalescer fuel filter system contains a primary coalescing and a secondary polishing stage. The coalescing stage has multiple layers of specialized media that traps dirt and extracts finely dispersed water out of diesel fuel.

The secondary filter strips away remaining water and polishes the fuel.

The Racor coalescer system provides up to twice the life when compared to standard pleated media filters.

The unique can design is proven to resist impact and seal deformation, "will-fit" reproductions may use a different, unproven design.

I bought and installed one of these filters from Madjack recently. It was the first time I had ever replaced the fuel filter by myself. The o-ring was a little tricky but nothing to cry about. It took about 30 minutes and in the few thousand miles since there has been zero trouble. I will be ordering more of these filters.

As good as OEM!

Hard to get o-ring to stay in groove

I had the same trouble as another reviewer did with the o ring but I got it in place by spreading my hand so that I pushed down on all angles at the same time. I would never use another Wix filter. The wix filters are now made in China and the canister is tapered in so it can't hold the filter media that a Racor does. Cut one in two and compare.

Great Filter

This is a great filter, came with everything it needed and installed with no issues. If you do a filter cut comparison to other filters, it is as good if not better than other similar designed filters on the market.

Not recommended over Wix

I switched to the Racor filter from Wix. The top o-ring groove on this filter is not significant enough to allow the o-ring to stay seated properly while installing the filter. I had to remove and rescrew it three different times before I got the o-ring to stay put and seal properly. Every other time it leaked fuel when priming. The Wix has never given me this problem. I will be buying Wix fuel filters for my Duramax from now on. This is in no way a negative review of MadJack Racing, Dane provided excellent pricing & service and I will continue to buy from him.
