Hey everyone I searched a bunch with no avail. I thought I would share my fix incase anyone has the same issue. Before I bought my LSXRT I had replaced my injectors with FIC (fuel Injector Connection) 42# drop in bosch style injectors with the EV 6 Connection. Fast forward and I buy a FAST LSXRT and the matching fuel rails for the truck injectors. I install it all and it all seems well for 200 miles. Then I go out of town to a show and while driving in traffic I smell fuel. Pop the hood to find an Injector leaking from the top o ring. It took 3 tries to get it back together on the side of the road to limp to the hotel. I start digging and find out even though I have installed the larger o rings my injectors ate dropping to deep into the intake. FAST tells me to go to the hardware store and buy washers to drop into the holes. Ummm not what I wanted to hear. So I call Bob at FIC and he hooked me up with the fix. He has machined stops that fit onto the bosch injectors and prevents the injectors from going to deep into the hole! Pics included!
