Doug:
Your question was timely, since I have been working on the fuel system and was just getting ready to post some details. You are indeed correct regarding the pump and regulator. This would be an ideal system for you as well and would not be overkill. The key is well regulated low pressure. The jetting won’t change the need for the low pressure input.
Here is a parts list. Installation details coming.
Fuel System, Part I
The components selected include:
1 Carter P4600HP fuel pump
1 Fuel filter, 10 micron, TNK-FF-10
2 pkg Hose clamps, 3/8”, EAR750006ERL
1 Aeroquip pressure regulator, 13222
2 DEK-6-02-0501 hose barb
1 DEK-6-02-0717 cap and plug
1 Thermo-Sleeve, THE-14005
The Carter pump is a rotary vane style with an output pressure of 6 to 8 psi and plenty of flow volume. American made, it should be well suited to this application.
The Aeroquip pressure regulator is a pricey item, but my experience with the more common inexpensive regulators has not been good. We used this same regulator on the GT 40 with its four Weber IDAs and it has worked very well. It can be adjusted from 2 to 5 psi, which is perfect for the Weber side draft carbs on the Jaguar. The non-glossy finish should blend in well.
The fuel filter is a hefty unit, flows freely, yet has 10 microns of filtration which is much better than most of the inexpensive in line filters. It has a vintage look, although few will see it once installed.
