OK finally changing fuel system completely.

I'm doing the VP44, LP upgrade or addition and fuel injectors!


My confusion: My LP is a stock carter on engine, 14#idle & 10# WOT weak VP44 though, might be lower once the new VP is in.

So do I leave the carter in the stock location then add a pusher pump with a big line kit that I have from vulcan? If so do I use a carter as the pusher? How is the wiring pluged into the stock harness for the pusher? If the stock block carter fails will it plug up and not let the pusher through?


Sorry so long but desperate to get this right finally!

I thought about FASS or AirDog but I dont want loud pump.

Do I remove carter completely and put on on the frame rail? With or without filters? Does the filters replace the factory filter system? Do I remove the factory housing if I do the kit with filters?

I really just thought about doing the 95 on the frame rail but is it loud and is it really a high psi pump? Do I need anything additional for the FASS system< I have the Vulcan big line kit already in the box here. Or do I do without it if I get the FASS?

Sorry again for how long this went into detail but about to drop over 2K to get this thing to tow good!

Edit:
What are the real psi. for stock carter with pusher pump (2 pumps )
versus a FASS with and without filter?

 

for the 2 pump ? that depends on type of pumps used .fass will hold (mine)
17psi idle 14psi WOT with rv275 or mach 1.6s and smarty ,no problem

 

WHich is in the 20's psi#

 

I put on the Airtex pump from OReilly Auto parts for my wife's uncle. Seems very happy with it. Looks like a Walbro design and fits right in the stock location and plug in. Fuel cooled gerotor type pump.

 

Aitex, cheap, easy, and it works.

 

How bout the air dog with fitlers 500$.
Is it quiet though?
How but the Fass with filters is it quiet?

What are the fuel psi# ??

 

Stock carter will run 10-15 psi.
Your engines gonna be loader than any pump you put on.

 

What is the O'reilly part# for the Airtex pump? Can't find it on their site. Also, did you use the Vulcan adapters? I don't get a response from them when inquiring about this mod...

 

E7153 Airtex number, but you can type in in on Oreilly's site and it will come up.
