Fuel pump advice

Ive been doing some searching on SU fuel pumps, but still haven't found a definitve answer as to which type would be best.

I have the original points type pump, but I have also seen that there is a solid state version available.

How reliable are the electric type pumps compared to the electronic? I am planning on driving my mini alot, and will hopefully drive it to one of the IMM shows soon, so I'll be covering a fare few miles in it and need it to be as reliable as possible. My Mk1 is supposed to be my reliable, "luxury" mini for when my 16v breaks again. :lol:

Cheers
Matt

Go for the solid state converted one, it looks like an original and as the only real weakness in the original was the points, its supwer reliable too.

Good to know... I've just installed a electronic switch unit into my old SU pump. You are right, the points are not very durable. The last set only lasted 25 years posting.php?mode=reply&f=3&t=2163&sid=b ... 877de5b3f7#

So how often do the points go wrong on the old pumps? Do they generally need regular servicing?

Unusual for them to go wrong. There is more chance of a pump going wrong if it hasn't been used for a while and the cure for that is usually a good knock with a persuader.
The points tend to "stick" and usually need a clean to get them back working again.
Spent many a time crawling around under the back of Minis in the dark and always raining, twatting the pump to get it going again. Oh happy days. :roll:

Today I tried to fit my refurbished SU AUF fuel pump to the rear subframe . I do not remember how it was fitted when I bought the car, but I have a brand new bracket and the holes do not line up.The distance between the holes is too great on the subframe, much more like the distance needed for the PD fuel pump bracket.

When were the PD pumps phased out? The beach car was built in early 1961.

Could you post pictures of AUF pumps fitted to the subframe so I can help my poor memory?

Thank you.

Not sure if the fitment is the same, this is my 69 Cooper. There is a seperate bracket with captive nuts that bolts through the subfrmae then the split clamp around the pump body has a single stud that passes through the other hole on the bracket,

Thank you.

I do not have holes in the subframe in that spot, and do not want to make new ones.

My replacement subframe didn't come with holes for the pump bracket, so I'll have to be drilling mine too.

Ohhhhhh, that's one pretty bottom..... If I only had a nickle for every time I've been slapped after saying that. :roll:

Edited to add: Just a hey! From another Robin over on the other side of the swamp. I would imagine that the name is much more common over there. An internet search showed that there is less than 37,000 males named Robin left alive in the US.

I got myself a PD pump bracket an fitted the AUF pump on it. It fits, just. Do you think it will work, or does the pump have to be at an angle?
