I have this pump, never used as I went a different direction. Will let it go cheap along with extra bits laying around.

Nick,
Are you keeping the OE pipes or upgrading ?

I need to install all new so was thinking of using -6 through out.... just not sure on the Pollak dual tank valve, it's only spec'd to 65psi....thoughts ?


I could just swap out one tank to the new HP pump & have the other LP pump act as a transfer into the main one via the fuel return port, not as 'seamless' as the dual tank valve but does simplify things a bit from the pipework point. Would prob need a a one way valve in the LP feed to stop the 'Aux' tank being back fedd with the return line fuel.

I have been using the stock lines. Except from the Corvette fuel filter to the fuel rail. There I use a -6 braided hose.

I can tell you from painful experience you want to make sure your fittings are well over the max psi...i don't think there is a single fitting or line on my fuel system now that can't handle 200psi plus.

Andy call these guys and tell them what you need. amazing quality stuff.

That's one of my fears with the dual tank valve, it was never designed to work with the modern HP fuel systems. With the main & aux tank setup the HP lines would all be -6 & AN fittings. For the small extra cost the transfer line will be too, a Summit -6 check valve is only $46.

Earl's it is then

All the hose & fitting I'd planned to use were Earl's anyway... might as well keep it looking the same quality.

That looks very 'factory', I can't see why anyone would want to bother rebuilding a dead 3.9 or 4.0 with this option now available. Even using a junk yard 5.3 you end up with so much more power & torque.... Makes it a no-brainer really

Fear of the unknown! I bought a D1 to do a 3.9 drivetrain swap for my 3.5. What a huge waste of time and money that would of been. Couldn't be happier with the drivability of this swap.. Just ticked over a 1000 miles on my conversion and it still makes me smile every time i turn the key.

Agree - that GM looks "right" in the engine bay of a Defender.

And to add to what Phoenix said - parts for these are available at any chain store. Although not sure what you will need - the 5.3 in the Suburban has only been using filters.

That's what I've been trying to do with mine, keep as simple as possible.... hence the NV4500. I'd deff recommend the rocker trunion upgrade if you start with a used motor, cheap insurance
