ok guys and I am sure galls. What are you useing as your fuel return line for you pump stock what ever throw out ideas. I have the vulcan big line kit on my truck, and right now I am debating on going to a 1/2 line on the return line back to the fuel tank, solid no cuts, right into the vulcan draw straw to be sure there are NO airgaps in there.. all will have high flow fittings

so ideas are

leave it stock
use the stock steel fuel feed line 3/8
use a solid 3/8 hose all the way to the tank
use a soild 1/2 hose all the way to the tank

 

Leave it stock. About 99.99999999999% of people on here have never touched their return line and are perfectly fine. Myself included. Why would you wanna change it anyways?

 

well some one out there has to make up the 0.00000000001 % and then after that if some one else does It I can say everybodys doing it peer pressure. now really I am just thinking of when I install the vulcan draw straw that I don't line the idea of slideing a rubber hose over a metal line and hose clamping it to hold it's just right now I am having problems with loseing my fuel prime so I am about to just say the hell with it all replace all of the fuel lines, in my vulcan big line kit. and put the draw straw in at the same time, also good reson for repalceing lines that were installed in July, is the lines vulcan was selling the blue lines are NOT bio diesel compatable, but the new black lines they use are bio compatable.. also thinking about runninf dual stock lift pumps, or maybe a stock pump then a holly but thats getting off on a whole other ball of wax

 

so what I get from this all you all want flow up the wazoo. up to the pump and say how more flow = more cooling for the pump. well I Know some of the fuel gets spit out the exhaust but IN form of black smoke. what about the fuel going back in to the tank. the less reistance that has the easyer it flows. anyone ever thought that way
