This comes from a great company. Priceless in my opinion. Great fit f150, superior customer service
First one had a split in it, but the company had another on the way as soon as they found out. Stuff happens, but I had a new one two days later. Great company, and I’m sure soon as my truck is running it’s going to be a great part. 06 f150 fit great, due to other issues haven’t seen much action from it, but good oil pressure when it was running briefly.

good quality, quick ship
add this when doing your timing component replacement in the 5.4l 3valve, good quality, and easy install while front cover is off,

Great pump!
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.

I mean holy cow it starts runs and cruises better, engine temp stays in the center and there ...
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.

Made in the USA. Genuine Melling product.
Pump arrived as described and is stamped usa. Definitely corrected the light valve grain noise I was hearing with the original.

Two years strong on 4.6L 2008 Mustang GT
Put this in while doing a full timing job just for piece of mind. My 2008 Mustang GT has a 4.6L engine with all the phaser and oil pressure headaches of its 5.4L cousin, although the GTs seem to be a bit better off and have way more clearance to work on the engine. The car runs solid and gets driven hard and at sustained high rpms (with other mods and a tune of course) with no issues. You will need a flex ratcheting wrench to get the two bolts off the pick up tube from the old pump so you can slip the new pump on. I didn't have one and it was a nightmare but I used a socket and a pair of pliers lmao to get the bolts off. I did drop one in the oil pan and never got it out. If that happens to you, don't panic, the bolt shouldn't make it through the filters to the inside of the engine. I glued some strong magnets to the bottom of my oil pan just in case lol

Better than stock part.
This fit exactly and is an upgrade from the factory oil pump. My oil pressure has increased. I recommend this item.

Melling oil pumps are renowned for their manufacturing quality and that is why I bought this unit. The high volume pump is exactly what was needed for my V8 Ford Fairmont Ghia. I highly recommend this product.

Had to replace my timing chains on my 2005 f-150 5.4 ....might as well put in a good high volume pump for the next 100000 KLMS. Seems to work fine will have to install an actual oil gauge in the near future to see what it puts out.
