Melling Hi Volume Oil Pump 4.6 5.4 Modular Ford 20% more volume than stock, Model Number: M340HV

Good upgrade

It fit well and the higher volume helped with oil pressure.

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.

Great upgrade from factory unit, oil pressure has increased around 18% since installation. Was an exact fit for a 2007 f-250. Would highly recommend for anyone replacing oil pump or doing a timing chain replacement.

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.

Shipping was fast. Good quality part.

Good value for the money direct fit no issues loved it would recommend it

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.
