I gotta say, this simple device is extremely powerful, took my truck from roaring and burning oil, gas and the engine up to quietly humming along and giving me incredible gas mileage. 1986 Ford F250 6.9 IDI Automatic owner, this part worked wonders to get around the vacuum. Tim was also super helpful when I had questions. Fast shipping, quality part (repair is still fresh will update if I need to buy more to keep running after X months) but I feel like I really got my money's and peace of mind's worth. This site is keeping old badass trucks running smoothly and on the road.

Bought this due to my VRV going out. I had a terrible time trying to get the modulator to fit. It kept hitting the crossmember right under the transmission mount. I spent hours the first day trying to figure it out. Slept on it and spent half the next day trying to figure it out too. Called fitzall and the guy that answered was trying to be helpful but ultimately all the advice he gave didn’t solve my problem. Called accurate diesel and talked to Tim. He suggested replacing the trans mount (pretty obvious once he mentioned it’s probably 40 years old). $16 and 30 minutes later and everything fit and worked great.
