   LB7 fuel injectors and deluxe install kit, April 10, 2018  By Larry (HUDSON, NH)
Wow
What great customer service. I called twice asking questions and got straight forward answers no pressure sales. Then decided to purchase eight fuel injectors and deluxe installation kit on next phone call. I watched videos and ask questions everything for me went smooth I have a stock lb7 fuel mileage is at high teens in town and low to mid twenties on highway196500 on odometer at first change of injectors I like the thought of matching injectors only wish the test results came with the the quality injectors all packaged and capped in a quality heavy MA box All I can say is great job for M A well worth the phone calls thanks again

These things perform better than I expected. My balance rates are amazing, and the truck never skips a beat. I couldn't be happier with my purchase!
   Nice 8 Pack Injector Kit, April 10, 2018  By Bryan (Ozark, AL)
This kit came with everything needed to do a quality repair. The injectors are nice because they are new and not re-manufactured.

Absolutely awesome! Everything I needed for the replacement!
   Deluxe Kit Worth Every Penny, April 10, 2018  By Anonymous (Riverton, WY)
The deluxe kit comes with literally everything you need when doing an injector swap, and then some.

My LB7 severely needed new injectors and I came across this deluxe kit provided by Merchant Automotive. Filters, O rings, gaskets, new hardware for valve covers, fuel primer pump rebuild components, tools, fuel lines, AND brand new injectors with no core charge for under $3,500? This kit is bargain compared to what others are asking for just a set of re manufactured injectors and new lines.

Everything was neatly packaged and clearly labeled. The tools provided are handy, especially the injector puller. Replacement hardware for the two piece valve covers are a must have, and the fuel filter assembly spacer is a nice touch.

My 380k mile LB7 now idles smooth with zero haze, and has excellent oil pressure. I would recommend this kit to any LB7 owner looking to swap out injectors.



   These are the injectors you are looking for, April 10, 2018  By Steven (Cocoa, FL)
The stock injectors in my LB7 made it to around 160,000 on the stock tune. Knowing the LB7 has limits on a stock bottom end, I ordered some overpriced % over stock injectors with a matching injector pump. A little later I had my local mechanic drop in a DSP5 switch and EFI live tunes. Nothing a stock LB7 shouldn't handle. The first time I pushed the #3 tune to the limit, I lost 2 injectors, filled the crankcase with diesel and barely made it home. 21,000 miles is all I got out of them, from supposedly the best shop in the country at the time. I've only got a few thousand miles on the truck since installing these injectors but I have run the crap out of it regularly and so far so good. I have actually pushed these injectors harder and more often than the last set and there have been no problems at all. Plus no cores.
   MA new injectors, April 10, 2018  By Gary (Mead, WA)
Installed MA new injectors with the basic install kit in my 2003 GMC 3500 witch has approximately 137,000 miles on it. The main reason I went with the MA new injectors as opposed to reman Bosch is because I didn't want to deal with time and money of core charges. Before & After the injectors arrived and I started the installation I had couple of questions for MA, they answered the phone with a real person on the other end great customer service. So far I am happy with the MA new injectors my first test drive my truck average 25.4 mpg over 75 mile highway drive, that's pretty bad ass for a 4 door dually. So far the only negative thing I can say is that the basic install kit is a little priced. I will be ordering a lift pump next.
