wigenOut-S30 Posted March 2, 2009 Share Posted March 2, 2009 I have a Mallory 4309 FPR. I bought it second hand about 4 years ago. The issue is.. since my car is down for now waiting for my turbo to come back. I took the interior out and installing my new black carpet. I noticed the filter on the vacuum line going to my electronic Boost controller was yellow. I took it off and it had coagulated fuel in it. I did have this vacuum line T'd off the line going to the FPR. So I am assuming the FPR's diaphragm is leaking. I was researching on a rebuild kit and found it.. but also found that my 4309 Mallory is supposed to be used in a carbed application and is rated from 3-12psi of fuel pressure.. Has anyone else used this mallory with out issues on your FI cars? I'm reluctant on getting a rebuild kit if I shouldn't be using this FPR on a FI setup anyways...

attworth Posted March 2, 2009 Share Posted March 2, 2009 Just a shot in the dark, but I imagine it shouldn't be used with FI. Quote Link to comment Share on other sites More sharing options...

I have been using it for like 4 years on a EFI car.. I doubt I will use it any longer for my setup. Quote Link to comment Share on other sites More sharing options...
510six Posted March 7, 2009 Share Posted March 7, 2009 Mallory makes a really nice EFI regulator, I have used one for the alcohol side of my fuel system for over a year now with no issues. http://store.summitracing.com/partdetail.asp?autofilter=1&part=MAA%2D4305M&N=700+310464+115&autoview=sku Quote Link to comment Share on other sites More sharing options...
