I have a Russell hose and -6 AN fittings as well as a LSx fuel filter/regulator for sale. I had these on my 99 Miata along with the stock fuel line as the return which I can also include if you like. There were no leaks (and it was not over-tightened like many do) and everything (except the stock return line of course) was on the car less than a 100 miles. My DW300 seemed to blow by the GM regulator giving me 75 PSI at idle but the fault might have been a kink in the return line as others seem to have run this setup with no issues. At any rate, this is a good start if you plan to go this route. I'll be honest and say that with the pressure spike I have no idea if the filter/regulator is hurt in any way or not. You will need a hard line adapter to connect to your existing hard line going to your engine. Shipping will be free to the 48 states. Any questions, just yell. $75 OBO.

Thanks
