    Bought this to fix a stumbling idle/bucking issue while driving. While this wasn't the problem the old Walbro had been in there a 190LPH for well over ten years and an upgrade was due. Very user friendly everything was included to make the switch simple. Of note * when installing the sock/filter there is a tab located on the pump mounting assembly that needs to line up with the mark on the sock/filter to ensure that it sits properly in the tank baffle, nothing was noted on the instructions but my round peg in square hole decision making figured it out, after having to buy a new sock, because you will inevitably tear the old one when removing it. Pump is much louder than my previous models but in order to push more fuel I'm sure that's a necessary evil. And besides who drives a Mustang to be quiet!?! Not this guy. MERICA'!!

    I bought this a month ago to replace my stock one that had rusted out thanks to ethanol and the car sitting for a while. Having no electrical background I was sure I would mess up the install somehow, but it was very straight forward thanks to the instructions. The pump hardly makes any noise too!

    Image uploaded by Chris  C. So after you get the tank down, this is an easy job. Pay attention as your take everything apart, read the directions and it will be back together in a few mins. This is a must have for any motor build. Works great, and is nice and quiet.

    By on 6/3/2014
    I own 2 foxbody 5.0 Mustangs, an 88 GT and and 89 LX. This is also my 2nd Walbro 255 Lhp High Pressure fuel pump purchased from Latemodel Restoration Supply. I purchased a pump for my 89 LX a couple of years ago. And I purchased another pump for my 88 GT 2 weeks ago. The pumps are of the highest quality and Latemodel Restoration has the best prices around. These pumps are just what I needed for my modified stangs! The staff at LRS are very helpful,friendly, and professional!

    5 Stars   Easy to do
    By on 1/26/2015
    Easy to install you'll need a jack, jack stands and a friend to help out for sure. It's a fairly quiet pump a little louder and more noticeable than stock (which I liked) should be enough pump for most engines I'm building a 408 stroker currently.

    5 Stars   The goods!
    By on 6/20/2014
    The pump went in as designed. Only drawback is the house that comes in the kit. It is "S" shaped so you cut off what you need. Would be easier if the hose was more of a direct fit or even a straight hose.

    Fixed my issue and I'm very happy!

    I purchased the fuel pump to upgrade from the stock pump that wasn't keeping my fuel pressure at a consistent psi for my h.p. 347. Since the install, no issues with dropping fuel pressure. Easy install aswell.

    5 Stars   Fixed the whining!
    By on 7/1/2015
    After my car ran for about 30-45 minutes I would start to hear a loud whine or groan type noise from the fuel tank, especially on a hot day with less than half a tank of fuel. Turns out it was my stock fuel pump crying uncle. The car also seemed to loose power at higher RPM's under load. After installing this pump the noise is gone and the car pulls better at higher RPM's. I'm very happy with this kit, I'm confident this pump will be able to feed the Ford Racing 306 in my car with no problems and handle any future mods. Thanks LMR for having a great site with quality parts!!

    5 Stars   Absolute best bang for the buck.
    By on 5/1/2015
    Bought an SN95 not running do to a failed fuel pump. Shopped around and landed on this pump set. Direct fit, easy install with video on pumps item page.

    Plenty of capacity for upgrades, but still works with the stock fuel system, no other modifications needed.

    Only possible down side, is pump noise, you can hear it in the car only at idle.

    Be sure to also order a fuel tank filler neck gasket (ripped on removal) and the external fuel filter.

    By on 4/29/2015
    My 89 thirst for fuel was becoming higher and higher with added susupercharger. Already as a heads,cam,intake, and nitrous car, figured it was time to replace the old 225 that was in the tank for new one. The old one did it's job for a long time, so I bought the same pump and replaced it as a "just in case". Used these pumps in my cars for a long time never had one fail. Great product, great price.

    Call me crazy... but my car would never spin on second gear pulls. but after installing this bad boy and hitting the gas my tires broke lose! I was in shock for a good bit because my car would never do that. as far as installation goes; needless to say it was breeze with LMR's videos on dropping the tank and fuel pump installation. put it this way between a friend and I both being 17 we did everything in 2 hours total. do i recommend this? of course! awesome fuel pump. i usually buy bbk parts but I'm glad i saved the money and went with walbro on this one.

    Bought this about a week ago to replace my factory fuel pump. Fits like OEM pump, no problems other than getting the filter on the bottom of the pump. Had to use a small hammer and tap the filter on. Other than that it was a straight forward install. Great improvement over the stock pump.

    I am sure the pump is great and works well, however, while the description says it fits 1986-1997 Mustangs, it does not fit a 1996 Mustang Cobra...
