Anyone tried an SU Fuel Pump ?

[Col_Callan]

Hi there.
As per above? Any views - I know they are old and have points, but they are serviceable, available as low pressure units, can be put fore or aft, stop pumping when float bowls are full and start agin when they're not.

Has anyone used one in a stock carb'd wedge?

I have done a search for them in the forums but most appears to be concerned with going for Facet, Holley type and upwards and then faffing with pressure regulators etc.

Im sure there's a v good reason why not,.. but why not?

Am braced and ready to be shot down. [B)]

<font face="Comic Sans MS"><font size="2">I've not buggerised around with them since I had the Jag, but I see no reason as to why you couldn't use one, that provided a suitable flow rate at the required pressure.
They don't all have points there are electronic versions and I recall there was an electronic conversion kit for old points type pumps.
Cost is probably the biggest problem with using SU pumps they aren't cheap these days!

Here is a link to a Mob here in OZ that sells them.

So there must be someone selling 'em in the UK too.</font id="size2"></font id="Comic Sans MS">

I had one in my TR7 V8 DHC, it supplied enough for an Edelbrock carb & worked fine. It was on the car when i got it. My only small complaint was that you could hear it rapidly clicking when you first started the engine, & a little at idle. When driving you could not hear it at all.

I should think Burlen Fuel Services would sell them, seeing as they are purveyors of all things SU.

I have a Mitsuba pump on my 7V8.High volume / low pressure and displays the same charachteristics as described by Tony. Still reliable after 23 years. They are advertised from various places on the net but not cheap.

The SU pumps work well - supply the twin crabs in an MGB ok - so why not in a TR7. But WHY?? What's wrong with the standard pump?? Oh - and AVOID the electronic SUs........stick with good old points.

The fact that the OE pumps are scarce these days and the generic ones are rubbish, is probably a factor in exploring the alternatives

Any particular reason why these should be avoided?
From what I've heard they are much more reliable, the only problem I've heard of is the circuit boards can get toasted by constantly trying to run then with clogged filters, which used to burn up the old points too.

Hi Col,
See the general discussion on fuel pumps and my reply on 12 Nov 13 under page 2 of Hasbeen's "ticking bomb" thread.
My reply includes some pump specs and a link that will take you to the Fuelflow manufacturers site in New Zealand. Fuelflow make a series of "ecco" branded electric fuel pumps that includes similar/modern clones of the SU diaphragm style pump in various pressures and flow rates. I believe these pumps (or similar) are also carried in UK by Robsport (numpty9 on UK Ebay).
Rgds, Daryl M

I have one of these in the mail, from a Brisbane, Queensland supplier. I think it was A$89.00, or there about.

I will report how I find it.

Thanks for the info on this all. It does appear to be a "you pays your money and takes your choice" debate.

I took the plunge, and shelled out the princely sum of £26.50p and bought an unwatched and unused BGT (MGOC Refub) SU pump from Ebay. If it is as-sold, (still in its packing etc) and it does pump the right amount at the right pressure then Ill be the happy bunny. If not I've bought a pup that I can resell.

Ill bench test the pressure as per Mildred's good vacuum gauge tip in the "Ticking bomb" post and see how it behaves.

It will go on in sequence along with the new head, part of my post Christmas task - normally prompted by the first sounding of the:
"When are you back to work Dear?" statement.
Ill post any relevant info that comes to light.
