Awesome, thank you so much for that info. Does the LT1 come with a stock regulator somewhere already on it? > [@Film : Grindhouse (Review, trailers and more)](https://forums.speedlife.net/t/film-grindhouse-review-trailers-and-more/25746/50): > > 45 would be a good pressure to run. i think stock might be 43psi. but anywhere from 42-48 would be fine for a LT1 > > an adjustable fuel pressure regulator is necessary for tuning fuel pressure. but using a stock one would be best…and hopefully its in working condition as they can go bad. stay away from accel LT1 FPR’s…i have heard bad things about them…breaking and/or not holding right pressure after 1-2 years of use. Aeromotive i believe makes a nice unit but its around if not over 100 bucks Yeah, I’ve heard bad things about ACCEL in the past, both with their electronics and their fuel pressure units. If I ran anything, it would be Aeromotive, but like I asked sailor above, does the LT1 come with a stock regulator? I don’t plan on running anything outside of the stock engine for the first year or two, before an eventual bore out/stroke to 383 and a cam. But that is in the future, when I can buy an aftermarket if there is already a stock one on there. --- _[View the full topic](https://forums.speedlife.net/t/fuel-pressure-regulator/187423)._
