snw blue by you Posted October 21, 2005 Share Posted October 21, 2005 Regarding the thread "F-450 from hell" there was an issue with testing fuel pressure while mobile. Everything you need is available from the Home Depot, or other home improvement/hardware stores. 1/4" polyethelyne tube,compression fittings,and adapters for the fuel pressure test port and your mechanical gauge are all available in the plumbing dept. If I remember correctly the tube is in 25'lengths, so you can make it as long as you want. This was showed to me by a Navistar engineer, is so simple it's stupid, and cost a total of around 5 bucks! I use this all the time , and it is easy to switch from a diesel to a gasser. Screw everything else, this works! Quote Link to comment Share on other sites More sharing options...
ktmlew Posted October 21, 2005 Share Posted October 21, 2005 I used a "retired" fuel pressure gauge I had in my box that has a 4-5' hose and just stuck the guage under the wiper arm. Just had to buy one fitting to adapt the air test fitting, a 1/8" pipe to 1/4", to one of the other unused fittings in my kit to make it a quick-disconnect set-up. If I were doing it over I would try to come-up with a 45 degree fitting so you can get it past the top rad hose easier. I actually got the WDS to work briefly......suspect operator error kicked-in...... Quote Link to comment Share on other sites More sharing options...
