i've got no reason to believe it isnt a good kit, all the stuff is well made, it comes complete and so far the only issue i have had has been with the tank mounting kit.....
i ummed and ahhed about this when i bought it, my thoughs were 'why is so much cheaper than the other kits' the only answer i can come up with it that it isn't a branded kit and so it cannot command the premuim.
it comes with the same guarantee, it does the same job and on face value looks to be more complete than some of the dearer kits (some of them you have to buy the diagnostic leads as an extra and the s/ware)
For some strange reason i had another 6 cyl front end kit arrive at the house yesterday

today i got a phone call asking if i had seen it, initially i was playing it cool and making out i wasnt too sure until the company confirmed that they has a signature and that my tank mount kit would be with me tuesday, there had been a shipping error and i had received someone elses kit.
