I was wondering if anyone had managed to convert a 748E to quick release connectors on the fuel pump plate? If so, how did you do it? Any recommendations for sources of connectors? Thanks Andy *Note I've changed my question from "dry break" to "quick release".
I'm not sure how the pump plate is made on the 748E but, I would think the easiest way is to fit a plate from a 916/748/996/998 if you want to use the screw-in CPC connectors? Otherwise get some inline connectors and fit them to the fuel lines. In either case the CPC connectors are the way to go, I got my metal replacements (an upgrade from the OEM plastic) from Tom Parker in Preston; https://www.tom-parker.co.uk/ The parts you want for the 916 type pump base are; CPC - LCD10004V for the tank connector (NPT threads) and CPC - LCD23006V for the hose connector. Make sure you either get the 'V' suffix on the part as this denotes Viton 'O' rings or you get replacement Viton 'O' rings and fit them before use, in fact get some spare 'O' rings at the same time anyway as you will likely need them in the future and they're cheap enough. If you fit them without the Viton, they will swell up in contact with fuel and fail - not a huge problem on the hose fitting as you can easily replace them (in fact it's good practice to replace when servicing) but the one inside the tank connector can block the fuel flow if it swells leaving you stranded at the roadside (mine did as I unknowingly bought the fitting with non Viton 'O' rings) and to replace the 'O' ring on the tank fitting you need to remove the fitting from the tank which is fiddly and you risk breaking it. Also when fitting them, there isn't much room to get a spanner in there and you want the fitting to sit the right way round so that you can push the release button so, the best way to fit them is to remove the push button, spring and locking mechanism so that you can use a socket to fit them and get them to the correct orientation. But be very careful if you remove the spring as it can fly across your workshop, meaning you have to buy another fitting because it won't work without and then (of course) a week or so after fitting the new one, you'll likely find said spring - don't ask me how I know. They are a tapered thread so shouldn't leak but be careful not to break them as they get tighter as you go. I used 'Slic-tite' pipe thread sealant on mine to make sure they didn't leak and have had no problems, PTFE tape maybe OK also?
Great answer, thanks. The connectors on the plate are banjo bolts, so are most likely parallel thread rather than tapered like an NPT. I wish I had measured them when I removed the tank last, but I would assume they're metric. I'll confirm when I remove the tank next. Due to the price of used pump plates inline connectors sounds a sensible way to go, unless I can get a metric socket to screw into the existing plate. I'll take a look at Tom Parker. Thanks again.
