If I'm Lucky enough to get a refund from taxes this year I would like to purchase either a DTT Assasin or A FASS Titanium 95 or 150.

My question is must I modify the stock fuel lines or put in a sump if I go the Fass route or can I reroute the stock lines to the pump?

  • I appreciate all of this stuff but after @trreedand @W-Ts dissertation above I think me and the micro Henry's are going to have to sit in the corner for a little while.

  • A fuel heater is going to do absolutely nothing for the fuel in the tank. Do whatever you want but that little tid bit negates the fuel heater in the bowl or on the lift pump.

  • Air separation is a HUGE farce that should not be carried into any decision for a fuel system. Stop it.

You keep the engine return line. You need it. Not sure how the FASS connects to the supply.

Heard of folks working the stock pump into the system. Never done it myself. My AD runs thru the stock filter canister. Also I do not have a sump and have no need or desire for one. My fuel module is capable of draining the tank. I don't want a big hole in the bottom of it. Just my preference.

Hmm ok so how do I connect the Fass return guys?

 

Yea I tend to agree. I’d rather not have a hole in my tank

*sigh this is what has kept me from upgrading to FASS or AirDog... both of them have their warranty process as a cross-ship but if I'm thousands of miles away from home I don't want to sit and wait for the shipping, I want to be able to go to a store and buy a new one. And of course a spare would be pricey.

 

Has anyone done what I was reading about recently where you add a SUMP.. definitely beans single hole single o-ring, the fass one has like 20 screw holes which seems like a leak waiting to happen... then a AirDog or FASS up to a ball valve and a T feeding into the stock canister filter/heater?

 

I'm thinking that is the route I want to try so my stock system is still there, just turned off at the ball valve and the harness disconnected because its connected to the better pump, and if anything should ever happen I could at least move the harness back to the stock pump and flip the 2 valves to the opposite positions and be back up and running.. Thoughts?

 

Had the (great) ??experience of fass quitimg at very bad location.  Nothing bad about them though...over 10 years old at time.  Now I'm set up with fic fittings and 80 dollars carter pump under back seat.  Takes me 20 min to...turn shut off valves, unscrew failed pump and screw back up carter and move elec connection.  Then open valves and start.

 

Was at rv park when it failed

  Couldn't do the work myself and ended getting hosed in process.  Vulcan diesel got me set up with back up pump.  Should it ever happen again...not going to be hostage to mechanic that has to call his brother we 150 miles away to translate spanish to english to order parts.  

Fass suction connects to the stock supply on the basket. No modification to the basket required. The fass return will be plumbed to the filler neck

So it sounds like you're doing exactly what i wanted your fass with the carter backup? whats a fic fitting?

 

It may not be optimal may be lower power but i definitely like the idea of being able to move while I wait for the replacement large pump. I like redundancy.

Its a type of flared fitting similar to an AN fitting.

I understand that part. What I need to know is where does the other end of the return go? Someone said yo uleave the factory return line hooked up?

I'm confused by the question.

The so called mechanic ordered a air dog ( they have a guy that speakers "habla" .  Anyway call Vulcan diesel ask him what do you need to swoop out your pump should it break middle of now where.  I think fass and airdog have different elec fittings.  Which ever way you go.

Ok let me try to make it easier to understand. So there is 2 ends on the return line. One of them goes into the filler neck of the gas tank. Where does the other end go?

There's two return lines. Stock stays in place. Fass return gets put to the filler neck return that's in the package to you.

Right I understand all that. Lets focus on the Fass return line. The one end goes into the filler neck but where does the other end of the Fass return line hook up too?

...to the Fass...

It sure can be confusing :ahhh:

There’s 2 connectionsnon top of the fuel basket. Which one is the pick up line? Right or left when facing drivers side of the truck. Sorry I know his is confusing too!

You've got the old school basket. I think its the left tube. You should be able to follow the tube from the filter toward the injection pump.

Thanks. Ifs rather hard to see the lines on the inside of the frame rail as the fuel tank is right beside. We will get it figured out though. Got a big line kit from filter to injection pump installed and preparing for the Fass to arrive tomorrow and get back on the road! :cheers:

It is the bigger of the two lines. Towards the rear. (Right side)

Yes, what he said^^^ at least on mine. Although I didn't like pressure swings so I completely modified my basket, now I'm happy.
