So many lines! What do they all do?

A friend of mine works at G&R diesel performance, they make all sorts of performance parts for newer trucks but they also have a universal sump setup that my buddy said he'd give me a heck of a deal on so I'm really thinking about that to eliminate any future draw straw issues

The water and salt in the used fry oil probably didn't do any favors to your draw straw.

Let us know how that sump works.  I'd be interested to see the install.  Some of the fuel injection swap folks might too.

I certainly will keep you updated, although I don't think the ever ran the bio stuff in the regular tanks, just the rear center tank I think. I should be getting my sump back from a machine shop tonight. I had to modify it a little bit

I finally got my sump back from machining, I had a recess grooved in the backing plate so it would for sure seal against my thin metal tank vs. a thick plastic tank. I also advised my buddy who works where they make the sumps to include the recess in the backing plate on all the new ones. I'm waiting to hear what he says..., I may get to still install it tonight. Draining the tank is a slow going process....

So I tried installing last night and it was a no go because the bit they supply you with is for plastic and wood, but I thought I'd try any way... So needless to say, today at lunch I went to the Home Depot and bought a hole saw blade that was an 1/8" larger than I needed but they didn't have a 2-1/4" like I needed, anyhow the hole saw worked perfect and I had it installed in about 5 min after cutting the hole, it doesn't seem to leak at all any I was able to position it pointing right at my fuel pump, quick easy, clean install once I realized what I needed to have.

Truck seems to be running fine now and not die on me but I haven't made a real maiden voyage yet to test it truly, however at WOT I'm only getting about 4-5 psi boost, and almost a vacuum at cruising around, turbo spins nice, I'm wondering if the waste gate spring is shot, I plan on making a boost buddy next anyhow... Any thoughts?

Exhaust leak can cause low boost(crossover), otherwise weak spring will do the same

Well my cross over does have some leaks in it, I just want to be sure it's running right before I put my flowmaster down pipe kit on it, comes with a crossover also

Drove around the lot a bunch from idle to WOT and it seemed ok other than the lack of boost, so I decided to take a road test, only drove about three miles but I romped on it and made some hard turns( use to kill it if I did) and popped the hood when I got back. The supply line was full and free of any air bubbles!!!! I finally have a healthy fuel supply.


Side note: the sump has been on since the weekend and had a full tank, hasn't leaked a drop

Wow!!!! All I can say is what a difference my exhaust work made, the old crossover was leaking pretty bad and looked like bubble gum welds. The truck runs great compared to what it did before, 14-15 psi at WOT and 3-4 cruisinghttps://vimeo.com/160476715https://vimeo.com/160476789

Very nice, amazing what no exhaust leaks can do for boost, hope most of the troubles are in the past now

Yes they seem to be, thanks for the help to everyone who posted, I'll probably keep updating this post with my other fixes for all of its engine/ performance related issues. I got carried away on a test drive  with out my Down pipe I place and melted a shock boot lol

These will give you a good laugh at the welds I found! the last one is the flange of my down pipe.



Down pipe will need modifying to make it work, flange needs to come off and then I need to possibly bend it some more and even shorten up the elbow to the turbo flange

Hacked the flange off and then the turbo flange, shortened the pipe on the turbo side and tacked the flange back on, I'll test fit tonight to see if it will fit inside the frame rail like the old one did...

Looking good, be sure to get some good pics of that down pipe install, I am going to have to do the same thing for my truck.

Does your truck have a body lift? Doesn't look like it, bumper seems to fit front  fine.
