Pusher pumps and Lift pumps

[Ted Jannetty]

This is in response to questions concerning fuel system upgrades.



This may not be the end all solution to fuel delivery problems but it has been in testing over the last 16 months on numerous vehicles with GREAT SUCESS.



Here is what we are doing and recommending for under 400 hp.



7 psi 100 gal. hr. pusher pump mounted in front of the fuel tank on the frame rail, cut in to the stock 3/8 line.



15 psi 100 gal. hr. pump mounted in the stock location.



We supply the pumps with all the fittings, hose, clamps, relays, fuse holders, terminals and wire to complete the install.



AN fittings and line to go from the lift pump to filter and filter to injection pump.



Auto Meter electric fuel pressure gauge mounted on pillar.



We use the original lift pump wires to switch the relays on and off, the relays will turn the pumps on and off.



Over 400 hp we recomend changing out the fuel lines and pickup in the tank to 1/2"



The ideal behind this set up is to gradually step up the pressure so the work is DIVIDED among the pumps.



You have gravity feeding the 7 psi pump, the 7 psi pump feeds the 15 psi pump so it's only job is to feed the injection pump and not pull from the tank.



This system will maintain 15psi under any situation and has been tested up to 485 hp.

Ted,



I see a lot of threads on the lift pump deal. As a new guy to all this (had my truck a month) I have a couple questions if you wouldn't mind answering. Is the lift pump a weak area of the fuel system, be it stock or BOMBED? Is the failure rate high enough that the dual pump set up be something a guy should look at doing to improve reliability for the future? My current plans are to go with guages and an Edge EZ at this point.



Thanks much,

Wayne

Ted, Checked you site month or so ago and didn't see this pump package offered, have you included it or should we call about pricing and so forth?? r, jbone

wtrenholm, the failure rate is high.

I believe this is because of location of stock pump and distance from tank the factory lift pump is working too hard pulling fuel.



I recommend to all 24 valve owners this;

Install a pressure gauge 0-15 psi, weather tempory or permanent.

Check fuel pressure at idle and while driving.

Idle pressure should be 11-14 psi

While driving it should NOT drop below 8psi.

If it is below either of these specs have the lift pump replaced under warrantee.

If OK just add the pusher pump.



If you are out of warrantee replace the pump with our 15 psi 100 gal. hr. pump.



Then add a pusher pump to prevent any future failures and take some of the load off of the lift pump.

Jbone;

The new pics of the pumps and install kits should be live now and they are in the price sheet, you can order on line if you like!

Or feel free to e-mail me.
