Works In Lincoln LS
I have a highly modified Lincoln LS. While looking for a fuel pump that would support my hp goals, I discovered the DW310m was a direct pop in for the Fords in 2000. With a squeaky clean record and proven results, I knew DeatschWerks was the best option for my build. Steeda provided the best price for the 340lph pump with super fast shipping. The item arrived quickly and completely unharmed. Upon installation, I noticed an instant difference. Sure, I monitored fuel pressure and AFR in the past. Everything always looked good in those readings. But, when after I installed the DeatschWerks pump, I could tell that my old pump wasn't cutting it. It's smooth sailing from here on out.
