Re: In tank fuel pump
You can view my "how it was done" in the section of this sit. In-tank is probably optimum way to add EFI to our cars. mine is just one way, but it worked for me.

Re: In tank fuel pump
You might PM Keith Tanner, he has been playing with fuel tanks and fuel pumps for his LS powered GT.

Re: In tank fuel pump
Yes, I did as well, a pump for TBI GM unit along with sender, ran a 3/8 and 5/16 forward to a pressure regulator with return, so far no problems.

Re: In tank fuel pump
Same. I have a Walbro 255lph internal pump with 3/8 feed & return. Currently running a carb so using a bypass regulator that lets 5psi thru to carb (adjustable from about 3 to ??) and the rest goes back to the tank. Plumbed it that way so I'd be ready for FI conversion if/when I get ready to do it.

Re: In tank fuel pump
I'm using a Professional Products 106533 like this but the price has about doubled since I got mine... [www.spiderautomotive.com]

Re: In tank fuel pump
Do a search for bypass regulators on Summit, jegs, or speedway. I saw some in the $60 range. One was a Holley unit.

Re: In tank fuel pump
Brand Aeromotive
Manufacturer's Part Number 13301 Part Type Fuel Pressure Regulators Product Line Aeromotive Universal Bypass Regulators Summit Racing Part Number AEI-13301 Fuel Gasoline Pressure Range (psi) 3-65 Regulator Style Return Regulator Location Inline Boost/Vacuum Reference Port Yes Boost/Vacuum Rise Ratio 1:1 Gauge Port No Mounting Bracket Included Yes Fittings Included No Rebuildable Yes Inlet Quantity One Inlet Attachment Female threads Inlet Size 3/8 in. NPT Outlet Quantity Three Outlet Attachment Female threads Outlet Size 3/8 in. NPT Return Attachment Female threads Return Fitting Size 3/8 in. NPT Regulator Material Aluminum Regulator Finish Red anodized Quantity Sold individually. Notes The installed low pressure spring will adjust fuel pressure from 3-20 psi, the included high pressure spring must be installed to adjust fuel pressure from 20-65 psi. Rob, This is the regulator that I used. I installed it with the new fuel tank from Todd Budde but initially used a carburator and was able to use the weaker spring for less pressure. After switching to EFI, all I had to do was install the stiffer spring and adjust accordingly. One time install. |

Re: In tank fuel pump
Hmmm... looks ike I should have done more research before I bought the one I got... I didn't realize I'd need a regulator when I switched to FI. Just assumed the injectors would work with the high pressure pump.

Re: In tank fuel pump
Rob, the Ford EFI systems have a regulator and depending if 93 or earlier has the return line requirement. 94 and later 5.0L does not have a return, but modulates the fuel pump pulse i think.

Re: In tank fuel pump
More common to see a fpr at the terminal end of the fuel rail, that way the fuel keeps the rail cooler.
