My TR3A has a TR4A engine but with SU H4 carbs. Today I measured the fuel pressure using my Harbor Freight Vacuum/Fuel pressure gauge. It measured a constant steady 5.5 lbs. The fuel pump is from TRF and about 2 years old. I connected the gauge to the fuel line via the 1/4 inch hose I use to connect the fuel line to the front float bowl. In a BCF forum entry from quite a while back I saw several comments that Bentley and Haynes both say it should be 1.25 to 2.5. Will the 5.5 lbs of pressure cause a problem? And if yes, what kinds of problems would it cause? Thanks!

Bob
