The sales service department of Huco have just sent a follow up email about what they have found.
with the above mentioned fuels.
My reply to Dirk mentioned the fact that the LRP petrol in the Jaguar S type can go off and cause a smell because of lack of use of the car, did the fuel degrade and form some other chemical?
You may want to read what this was all about first?
I sort of got the replacement Huco fuel pump replaced myself, Carl of Smiths Auto Spares tried himself but the Huco agents refused to recognise my claim. I felt I had a valid case,as even though my Huco pump was well past its normal one year warranty, the fact that the car it was fitted to had only clocked 1150 road miles and that the 1966 Jaguar 3.8ltr S type it was fitted to, has two tanks means the pump had only lifted a max of 150 litres in its life.
Make sure you have the correct pump for the application, this 443020 suits a car with the pump near the tank, its suitable for engines to a 3ltr size.
I have bought a couple of carb kits from Gower & Lee in Watford (Ph 01923-247300) and the chap who did the work commented that he’d never seen such good kits – comprehensive and good quality although pricey at £55.72 for a kit for both carbs. Anyhow, I e-mailed them and asked what they use for the o-rings (described on their website as –'O' ring for float chamber plug – item #27) and they came back to me very promptly telling me that they ditched all their old stock of o-rings and diaphrams, etc. and replaced them with stock made from VITON which they say is suitable for fuels that contain 5% to 15% ethanol.
Thought it worth giving them a plug as they have proved their worth to me over the last few years…
What I learned from the various parties I discussed the issue with at Huco, was that my pump was South African assembled with parts supplied from Germany, the pump was marked as being made in 2005. Those pumps were pre unleaded petrol, we had that unleaded and LRP (lead replacement petrol) petrol intoduced around 2005/6, I had been sold an old stock item, which was suitable for the old petrol only?
This took some while to sort out but the end result was what I wanted.
