Posted January 23, 20214 yr comment_614916 I installed the new 240 fuel rail this week . now at the start of the fuel rail my fuel pressure is 3.9 psi . so I checked at the rear carb and the fuel pressure is 3.6 psi . is the fuel pressure to high for the 4 bold carbs? thanks Link to comment https://www.classiczcars.com/forums/topic/64983-correct-fuel-pressure/ Share on other sites More sharing options...
January 23, 20214 yr comment_614920 The float valves should be able to handle 3.6 psi. If they can't, there may be a problem with the needle or seat in the valves.

January 23, 20214 yr comment_614931 Every carb I've ever dealt with could take 3.5 psi. I'd let it idle for a while and check for signs of flooding before taking it on the road and check things under the hood a few times on the first trip. Always a good idea to pack a fire extinguisher too.

January 24, 20214 yr comment_614980 Not sure how much a regular fire extinguisher is, but this one looks really light weight, but is priced at 79 bucks :0 https://elementfire.com/collections/allproducts/products/element-e50 Edited January 24, 20214 yr by heyitsrama Link to comment https://www.classiczcars.com/forums/topic/64983-correct-fuel-pressure/#findComment-614980 Share on other sites More sharing options...
