Swing check valve?, Brass spring loaded check valve?

[SLO_TAO]

I'd like to add a check valve onto my conversion to help prevent backflow of diesel to the veggie lines. Basically I have a two filter setup utilizing the existing stock fuel bowl. There is a T before the injectors where the veggie and diesel side meet. I would like to add a check valve right before the T on the veggie side. On McMaster there are a bunch of choices.. I like the spring loaded valves because they're low profile. What are people using here? I'm guessing there shouldn't be a problem with up to 1 PSI for cracking pressure to open valve? Thanks!

I was curiuos about this also. I wanna run FN74-style WVO set-up and I was suprised to see so many cv choices. [img]/ubbthreads/images/graemlins/shrug.gif[/img]

I think I'm going to go with a couple of these from mcmaster.com
8549T24 Brass High-Pressure Spring-Loaded Check Valve 3/8" NPT Female X 3/8" NPT Male, Viton Seat

I'll go with the Viton.. never know when I might use B100 as the start/purge fuel.

This thread is 4 years old. He has probably bought something by now. However, I use a few check valves at the shop and my favorite ones are made by Generant.
