I recently installed a walbro 392 and big line kit. I can my regulator backed down to around 15psi but then I can't lock it there so it won't leak in order to get it not to leak it has to be around 21psi. has anyone ran in to this problem?

 

I guess they changed the regulator from when I bought my unit. Mine was "non adjustable" in that there was no adjusting nut. I had to take it apart and tweak the spring and spacers to get my desired fuel pressure. Maybe you can do the same on yours?

 

Where did you buy your kit at? I am looking to buy the Walbro from Ebay with the install kit and the relocation kit from Geno's...but neither one mentions a regulator in the kit. Thanks

 

I bought mine from richard at glacier in his kit it has a bypass for fuel pressure to adjust you have to change a shim or a spacer
