No i dont feel lucky Steve... Not a luck person as it goes...!
This really provides a bit of a unwanted conundrum , because in doing some serious googling, of all the available pumps whether they are to be fitted with spacer or not, you get no consistency in pump arm shape, or dimensions… Really a lottery..
I decided to check the Rimmer’s product that they would provide if you order part 312167, and what you would actually receive is a longer arm version with the measurement being 65mm (body to end of arm). So with a 13mm spacer that’s 52mm, 6mm longer than my old AC Delco unit, and 2 mm longer than the Robsport.. Absolutely nuts…
Robsport to be fair said that they use these on Sprint’s but they do, where possible, advise their customers to convert them to electric fuel pumps, using their product FUE401 which is a pump they fit to Stag’s as well. I had hoped to keep away from an electric one due to the apparent struggles these seem to bring with getting pump pressure correct etc, but I am now wandering if this is the lesser of the 2 evil’s. I really don’t want broken metal in the engine if I can avoid it, but had wanted to maintain the standard set up….
I don’t suppose anyone might have a working original AC Delco unit hiding somewhere?? I know the answer to that, in that I have more chance of spotting Lord Lucan Riding Red Rum!!!
Thanks for your input Gents. Appreciate it !!
