Does anyone know if Napa sells a fuel filter for the LB7 Duramax? If so, are they any different than the ac delco filter?.. good or bad? and possibly a part # if someone has it on hand? Thank you.

Since the filters are all made by Racor, they should all be the same, regardless of who's name is on the box....Part number 3910 is the new design, part number 3810 is the old design...

My local NAPA is higher than the dealer on stock filters. As much as I hate to say it, I buy the stock "Delco/Racor" at AUTOZONE.

thanks guys... just looked it up on the napa and autozone websites, pretty pricey!! My grandpa has an account at Napa and gets a huge discount, so maybe that will bring down the price quite a bit. Thanks again!

I got my filter from Napa, I think it was just under $30. May be a bit high but its not worth driving another 25 miles to be big city.

For all military, their discount on filters is you get them at cost, fluids and everything else 10% off. Our last fuel filter was like $12 from NAPA.

I bought my last one last month for $18.00 at the dealer.

I buy the Wix 3810 series, seems like a good filter. Can't wait to try the 3910. I did not know that racor made all the filters, I assumed WIX made all their own.

My local Napa store wanted $42.00 for the new style fuel filter 3910, didn't buy from them. Going to check price at my stealer.

I paid $42 at NAPA last week. Have seen them from vendors on this forum for less.

We still carry the old style the INF4598 Racor for $18 and he new double pleated Baldwin branded for $28. The new ones if you buy 4 or more we pay the shipping.
