Fuel pressure woes

Okay, need some info from the pressure experts. Will it be better to y the second pump after the inline Bosch or just before the fuel rail. I've heard of people running some high horsepower with the stock lines. Just want to know what's best.

Your making this harder then it needs to be. 1 044 Bosch in the tank and problem solved. I ran the same set up as you but had a 255 inline, the 044 in the tank, never had a issue( untill the sock it self messed up FP) Still running a single 044 in the tank, FP is pegged at 60lbs all the way up to my shifts..

Really, is the 02 bucket smaller then the 03? I thought they were the same. I have a few hours it, it fits fine once you cut and trim the bucket. No more time consuming then trying to run Ys T's 10 feet of new line, fittings, switches, new wires and all that..

Yea. I've seen that thread. Even have the sock for the pump. And I have to drill and tap the tank so maybe 15 min there. Using gates push lock hose it will take about 20-25 min to route the lines install the y at the fuel rail. Run a wire from the battery to the pump, then install the Hobbs switch and run the wires. It's not too bad. I've run a lot of wires up the frame rail. And that's what I'm adding a another pump to keep from going lean. This is not a permanent thing. I just need something for now. I already have the fittings. 130 for lines and filter. I have the old Bosch 044 that I took off for testing and 70 for a check valve and Hobbs switch. So 200. Duel walbro 400 would be 400+ I'm getting ready for a move to North Dakota along with haveing a new wife and a 3 year old step daughter. So the truck is last on the priority list right now

Your just making things difficult on your self. This isn't reinventing the wheel here 
It's only a matter of time before the fitting falls the hell out of the stock PLASTIC tank, you have gas everywhere. 1 good pump in the tank will solve the fuel issue. Your going lean now because you have a tiny pump in the tank and the big dog on the rail trying to pull through it, 90deg loops and all. The more loops and corners you add to the system the more of a restriction it becomes. Just saying your doing more work then ever is needed for the set up and HP you are making. Sell all that push lock stuff and extra wires, hob switch, put the big pump in the tank with a hot wire kit, be done. Nice and neat, not looking like oh **** let me throw this together.. Not to mention your going to be in snow and all, the more chit out in the elements the more likely it is to fail..

^^ This. Better do it right this time, Andy... The first thing they're going to tell you at that base is how ridiculously dangerous it is during the winter. They're going to issue you a 50lb A-bag just in case to keep your *** warm if a vehicle breaks down on a dispatch. That's how nasty the cold gets up there. With a family, I'd consider reliability the primary factor with your fuel system.
