So I put the tank up in its spot under the rig and noticed a wet spot on the seam in back. Drat. Took it back out and epoxy was applied. Next day I installed the tank and started the engine just fine. Drove it a couple hundred miles over the last several days, today (Sat.) it stuttered and almost died at a stop. I managed to keep it running to a job I had. Shut it off and looked under the hood - didn't see anything unusual. * Went in, got some tools and started to drive to nearby building. Would not start. Just crank. Key off / on 6 times - no start. Pushed the pedal to the metal and held the starter engaged, it stuttered and gradually picked up speed and ran the block to the next site. (a little rough idle) I quit early and drove it home, checked the fuel pressure at the test port on the engine. 63lbs - holds at 61 after 5 minutes. Engine starts and runs fine sitting here. Fuel pump sometimes makes a rattling noise for part or all of its cycle when key turned on and not cranked. Not all the time. Can not hear if it does the rattle when the engine is running - too much other racket. Runs with 52 - 53lbs at idle jumps to 63 when 'goosed' . Its just perfect. Now. I can just see myself stranded on the way to a job. Not Good! I wonder do they make electrical sending units for gas pressure gauge to install permanent? I think I need to monitor the pressure while using the rig but don't like the idea of a fuel filled line that could leak.

No electrical pressure gauges I know of.
You need to get a pressure reading when it acts up.
Best to tape a fuel pressure gauge to outside windshield or or outside mirrow.
Always keep it outside cab in case of leakage.
And also watch power and ground to fuel pump.
And when it quits or acts check for lose of spark.
Any codes or check engine lights?
