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

This oil pump replacement is a must when you do a timing job on the 5.4 three valve Ford motor. Followed the advice and step by step instructions from a Youtuber and my Ford is running strong again.

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.

It runs beautiful no more rattle great oil flow

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.

As is found everywhere on the internet, this pump and its bigger brother the mh360hv are a must if you are opening up a 5.4L 3V, even if you are swapping engines, just do the timing components and change the oil pump. I put this in a used engine i got from the local wrecker (long story) and it produced 65psi at starter speed of 200rpm the first time i tried it, on 10w30 rotella T (for a second break in). It made 75psi at idle and held that until engine was warmed up then dropped to about 65psi again. This pump is a must. I used melling timing kit 3391scc with the cast iron chain tensioners and so far no issues (only 3 weeks on this engine). A note of caution: if you are considering the 360hv it supposedly makes 20psi more than this version and i would be concerned of the chain guides breaking or wearing prematurely at that high of pressure.
