Carter AFB fuel inlet problem

[mojo]

When I bought my C-V8 MkIII it had a Holley carb on it which leaked petrol horribly around the vertical bowl seals. Rightly or wrongly I chose to replace it with a 600CFM Carter (Weber) AFB, and it ran better, but with a slight problem with the fuel inlet pipework.

The problem is that the inlet is right at the top of the carb, but the C-V8 air filter base is dished downwards - presumably to increase bonnet clearance. The result is that the fuel supply pipe rubs on the underside of the air filter base (photos below). Is anyone aware of a proper solution to this? I considered fitting a banjo-type connector, but there is a linkage right next to the inlet which would probably preclude that. An inlet that is bent downward would be ideal, but I've not seen any optional different inlets for that carb.

Any other ideas that might prevent abrasion (other than the ty-rapped on DIY aluminium shield that appears in the photo!)?

Well spotted. That could easily cause a fire. The 383 had a metal pipe that runs from the fuel pump, up along the front behind the alternator, then along the V to the carb, and being metal, has a 90 degree bend then a few inches going up vertically into a banjo like fitting that the pipe connects with from underneath. So the fuel pipe goes up vertically to the carb, not in horizontally. Hence no clearance problem.

Here you see the banjo fitting, with the pipe coming up vertically to it. The pipe can be seen with a bit of the frayed lagging on it. This is a Mk1 FF engine bay. However the Chrysler engine pipework basically followed a similar route as the carb to fuel pump pipework is Chrysler. I don't think the 67 and earlier engines had lagging on that pipe. This is a 68 I believe. Anyone know?

This gives a better view of the pipe running to the carb.

Thanks - perhaps I should reconsider a banjo, though the choke cable assembly is immediately below so the only obvious route would be down and back at a 45 degree angle, which is not an ideal direction (i.e. it heads towards the bulkhead). it would be good to get a fitting that would take a flared pipe, which I could bend to shape and bring down to the front of the engine to meet a flexible, but I doubt the parts would be easy to get.

Probably the next step is to take the outlet off and see if I can figure out what the thread is. When I know that, I'll be able to search for parts that might fit.

I believe it is a 5/8"-20. That banjo fitting would often have an inline filter behind it on the original carb. If you look at Mikes carburettors you can find out more. If you search ebay/google with combinations of 5/8-20 and fitting, you get things like

Also quite a lot go to 6AN and 8AN pipe fittings.

Also this is a kit in stainless at Jegs for a 1966 383 charger with AFB, from fuel pump to carb. However, the FF has a one piece line. Maybe that is split in two for easy shipping? Something along the lines of that without the split is what I would like, ideally in stainless:

Thanks John - the Edelbrock 8089 might work out Ok - I just need to check the clearance to the choke linkage below. It would probably work better on the AFB with a spacer and a longer banjo bolt, but I need to do some measuring up.

While working on other parts of the fuel system (changing the plastic fuel line out for metal) I removed the banjo that connects onto the fuel tank and found that it was so badly rust pitted that it had actually pinholed through. So more banjo connector buying than I expected...

It's split because of a fuel filter that fits between the two parts. That's the way the mopars came with. The filter sits behind the alternator.

I thought the one piece line was a Jensen fitting, but recently found the 1 line Version in ss, part-no. RPC6809SS
