Pressure Line Length????

[maxx-breaker]

i AM CURIOUS ON HOW LONG THE PRESSURE LINE SHOULD BE. I RECENTLY SHORTENED MINE UP BY ALOT. MY HEADER WAS BURNING THE S**T OUT OF MY HEAT GUEAGE FOR THE HOSE. HERE IS A PIC OF WHERE I USED TO HAVE IT. i RECENTLY MOVED IT, SO THAT IT GOES IN FRONT OF THE MOTOR, BETWEEN THE COOLING HEAD AND THE HSN. WHICH MAKES IT ONLY LIKE 4 TO 5 INCHES LONG. hOWMUCH WILL THIS AFFECT THE OVERALL PERFORMANCE OF MY TRUCK? AND SHOULD I MAKE IT LONGER? PEACE :confused:

I find it funny that he had a side cutter to trim the zip-ties but didn't cut the fuel line?? :p:

I'm an innovator...... I had the largest Revo tank there. I didn't prodict the large pressure changes though. I forgot that it can only be done in real cars because of one key element. Fuel pump!

Maxx, there are different opinions on how long the pressure line should be. There has been some discussion on a couple of threads over at http://www.SGrid.com recently. Seems that some say 6-8" should be ok, others think maybe 8-10". Part of it depends on your tune, and if you are having a problem with your engine flaming after a pitstop, which is said to be a symptom of too short of a pressure line (most feel that 4" is too short). It builds up so much pressure in the tank, expecially when it starts getting empty, that when you open the lid to refuel, the pressure escapes, and causes some brief fuel flow issues. One solution was to run a gutted fuel filter in your pressure line. I know a couple of us had that problem last summer, and the filter trick worked. I have since gone to a longer pressure line, and no filter without any problems. I am running about 9.5" on my TTR with a P5, and about 11" on my LSP with modded P7.
