If this doesn’t belong in this section, sorry.

i dropped my tank to not only get it ready for the install but to really look at it. 
An 18 yr old truck just needs it - my .02.

anyway, I broke off the connection to the fuel line and noticed that the line - to the frame - had been crimped the whole time and always wondered why I got hesitation at WOT
question, do I need the fuel line or not ?

i highlighted the culprit.

Depends on what you have more of...time or money.

Time on your side...Bulk head fittimg for fuel supply, extend to length you want inside fuel canister with schedule 40.  

Return line drains back to tank via filler hose (between gas cap and tank)

Black plastic cap (only used in gas models for smog) get new cap from part store in vacuum line area. My old one cracked.  Had to drop everything just for $2.00 part Or jb weld hole air tight.  If you need any plastic to jb weld anything...plastic cap from mayonnaise jar or pill bottle. In other words plastic about as thick as what that canister is.

Or easy way just buy new.

 

Here is bulkhead fitting on my old set up.

Me personally I'd never put the straw in the sender. Being now your dumping hot 170-180*F fuel from the return of the head returning from the injectors. Like my truck the Fuel Temp and IAT run as a pair. I'm never over 130*F in the summer and no heat soak of the VP44 always goes down after the engine shuts down not up. Like yesterday being I draw from the fuel tank directly I was a mere 90 to 110*F fuel temps for the day and never return even close to the draw straw. All fuel is return away from the suction straw. This way I've got much colder fuel for the VP44 to cooled with. 

 

Been running this system since 2006 and never was a disappointment.

  • No 1/4 sloosh issues
  • No high fuel temp issues.
  • Can empty tank to the EMPTY mark safely
  • Much cooler fuel temps
  • Stable fuel pressures

As seen here IAT and Fuel Temp chase each other.

NOTE: Transmission temp is actually engine oil temperature. 

 

Note my location which is away from the sender basket with hot fuel.

Then note my straw nearly touches the bottom of the tank...

There's more than one way to do it, this is mine.

 

Very nice !!

You guys rock !! When I get my new module, I will definitely have some more questions as I have a little time with this endeavor.
