Turbo BS Thread

Whats the PSI when not idling? The vacuum source should be pulling psi at idle, so as soon as there is neutral pressure in the manifold the psi should spike

 

Is the vacuum hose to the FPR, sourced post throttle body?

If the gauge shows that it is holding pressure, after engine off, that means the check valve in the pump is working.

 

I might have missed it, but you're not hooking your FPR to a vacuum source, right?

 

What my question refers to as well.

@Jstand Pull the vacuum hose off of the FPR, and take a picture of the gauge again.

 

The vacuum line goes to the TB so if I disconnect it at idle there’s no change but yes connected it lowers the psi when you put throttle. When I first installed the pump months ago the psi was +-50 at idle after putting the injectors and all the trouble with the knock sensor was fixed the pressure was 40-43 psi and now for the last week it’s been less than 30 psi.
On

Off

 

Thats wild. Very well could be a fucked pump at this point. Was it ever ran dry? does the pump make a bunch of noise when running?

 

um, is there someway to have your fpr boost referenced without it seeing vacuum? like are yall running check valves or somethin? from the factory it sees vacuum (at least the 4.0 does) so why would this creat an issue?

 

No noise that I noticed and never run dry that I know of.

i was just thinking that if it holding pressure then the injectors, fuel rail and lines to the pump must be good no leaks

 

Unless your fuel filter is extremely clogged from the e85, then there is a pump issue.

All lines being good. Any way you can test the pressure pre fuel filter?

 

No I don’t have a way to check pressure pre filter but It looks like it’s narrowed down to fuel filter or pump so that’s good.

 

The 320lph AEM ethanol safe pump is like $90 from Amazon (

$129 AEM 50-1200 E85 In-Tank Fuel Pump, Black, 4.055 x 1.535 x 1.535"es

https://www.amazon.com/AEM-50-1200-...e=UTF8&qid=1517518909&sr=8-2&keywords=aem+320) and has been working great for me. Might as well do the filter at the same time.

 

Can check agp turbo as well.

 

Sure enough I’m trying to order this Aem patch harness 30-2983 and everyone keeps refunding the money after I order it it looks like I’ll have to get the one that URD has at $60 more.

 

Same problem I had.

 

@Jstand I wrote a tutorial on how to install this pump. Probably irrelevant now that you've been in there already, but here it is anyway.

Last night I purchased my Daily Driver for now so I can work on the truck


Payed $2000 cash and it has a turbo !!

 

Damn! That thing is nice AF!

 

What do some of you other guys use as your DD's when your boosted ride is down?

 

My brother sold it to me for 2k it has 193000 miles but he replaced a lot of important things.

 

i bummed a couple rides from my dad
89 or 90 t4r

and a mid 90's grand marquis we call "the boat"
