I installed a set of Siemens 55lb injectors today, and I noticed that they seem to slide into the openings on the intake manifold a bit easy. I compared the seals to a spare new Bosch seal that I had, and they seem ever so slightly smaller. Anyone have any problems with leaks with these injectors? They seam to seat on the rail pretty well, which as I understand it is the side that tends to leak due to the high pressure, but should I be concerned about the intake side? Should I swap off the Seimens seals for the unused Bosch ones I have?

When I installed my 55# injectors, I also had the impression that the seals were very slightly looser in the intake manifold than the stock injectors. However, the difference was small enough that I thought I may have been imagining things. After the installation, I inspected them regularly for leaks but there have been absolutely no problems.

Thanks guys

Mine seated nicely without leaks as well. Did require pushing down (towards the manifold) with a screwdriver to fully seat them.
