MellingOil Pump, Wet Sump, Internal, High Volume, Ford Modular, Each

Works great!!! Fits perfect, provides outstanding oil pressure. Used to replace OE pump in an F150 4.6 3v during a timing job. Essential upgrade to keep the timing and cam components happy in 3v engines. Make sure you pre lube the pump before install.

Easy to install and good quality.

Did a whole timing kit replacement (literally everything), oil pan and struts and added this oil pump in from the advice of a YouTube channel, fordteckmakuloco. This is a brand new 160k mile engine now with this pump. I mean holy cow it starts runs and cruises better, engine temp stays in the center and there is a strange silence as the vehicle is running... holy cow is all I have to say.This one is for the 5.4 3v engine and I was contemplating grabbing the 360hv over this one, after speaking with my boss ( also an aircraft mechanic) we both decided more volume is plenty. And to be fair I'm a believer.. but do yourself a favor and go watch that guys videos on YouTube for the walk through-it makes timing it a breeze and the tips for removing the oil pump were invaluable- seriously.I've worked on cars for years and stepped up to work on airplanes for the challenge but if youryoure undertaking this repair be prepared for a rough time with the ps pump.Oil pressures are absolutely stable, verified with my mechanical gauge and a digital real-time over the period of a 2 hour trip never dropped below 5 psi above factory spec. And for an extra 30 or 40 dollars over the oem replacement it's really a no brainer- stop researching and do the repair- after all the original pump is what caused all the vct and timing problem to begin with.

This is an excellent oil pump which produces about 20 to 30% more volume and pressure than the stock pump. I can tell on my gauge after installation, instead of the needle on the oil pressure gauge being in a center where it was before it’s about three-quarter now, I replaced the timing chain, the guides, the sprockets, and cam phasers. To me, it’s a no-brainer. You’re already in there, so go ahead and put this quality oil pump on there when you do the job.

Great quality and performance. Easy to install if you're already doing a timing chain replacement. Small cost for the piece of mind and reassurance youre getting adequate oil pressure to your new parts. Out performs original by far.

Installed on a 2004 F150 Lariat 4x4, 5.4, 3V (@180k miles):I did the full cam phaser - timing component job and replaced the oil pump at the same time.The M340HV pump fit perfectly and solved all oil pressure issues! My engine had obliterated its chain guides and ate 2 holes in the timing cover from the chain slap. It was a MESS inside. So if your Triton is tapping - Don't be a dummy like me and put it off. This problem will only get worse!I'm using Motorcraft 5W30 synthetic oil. At idle, I'm getting 70 PSI cold and 25 PSI hot. It also runs about 60 psi down the road. With the considerable damage my engine had, the oil pressure is amazing. My engine still has scored cam journals and probably the crank bearings too, so I didn't expect such great pressure! I would have replaced my engine completely, but I didn't have the money, so I'm hoping this fix will last me until I do. So far so good.I'm using the ratcheting chain tensioners as well as the upgraded rockers that have the smaller oil holes. The new rockers greatly helps the oil pressure up top. If you're already in that far to replace the pump - upgrade those rockers too!VERY happy with this pump!Oh an PS: Watch FordTechMakuloco on Youtube. He is the 5.4 MASTER and shows you exactly how to do these timing jobs and oil pump!

Good upgrade

Looks good
