electric fuel pump for weber - which one?

[slapper]

Well, the 32DIR on the 4K is haemorrhaging fuel (seemingly) from every available seal and partial orifice after a year of use ... well, there's a nice coating of red fuel and dirt shite all over it ... and I'm suspecting fuel pressure may be the culprit.

I'm about to slap a 32/36 on the 4AC and (in addition to fixing the 4K's problem) I don't want the same issues on this one ...

I have the stock 4K fuel pump pushing fuel into the weber - I think the toyoa pump is in the 7-9 psi region, where as the weber probably wants somewhere around 4 based on the web meanderings I have done.

So ... I've started looking for a suitable leccy fuel pump or pressure regulator, only to be confronted with so many options that I don't know quite what's what. The obvious question (of people who know more about this than I do) is "what's a suitable pump/regulator without breaking the budget?".

The local SuperCheap has a Facet Posi-Flow (1.5-4 psi) for $90, autoPro want to sell me a (no-name?) Hansa FP401 (4-7 psi) for the same price with staff at both shops claiming their option as the perfect solution to my problem.

What have youse people used (fuel pump, regulator)?
Was it successful?
How much did it cost?

If I go down the fuel-pump path, wiring it up will be okay - I have the necessary knowledge concerning Circuit Opening Relays, fuses etc etc

thanks,

7-9psi sounds high for a stock pump... but still not high enough to cause a problem like that. I think you need a carby kit, and tighten down your screws properly. I had a stock Toyota fuel pump on my 32/36 for quite some time with no dramas after a kitting. Then that carby went onto a 4k and stayed there for even longer. Both ran stock Toyota fuel pumps (New 18R pump on the first one).

The 7-9 psi is anecdotal ... I read somewhere that this is what the 4Ks do - of course, it could be nonsense! I can see a fuel pressure gauge coming on.

The carby was professionally reconditioned before it went on the car - I wanted one less thing to worry about. Hmm ... best I sort out the pressure iussue to start with and then have a think. Think I'll hold off on the 'leccy pump for the time being.

I have used webers on many cars over the years and one fact remains constant, they do not like excessive pressure. Too much pressure will push the needle of the seat despite float level being reached. My favourite pump is the carter electric, small compact easy to mount and quiet. Years ago I tried a Holley Blue but man the noise they make, great pump and fully adjustable pressure and lots of delivery on multiple weber systems but the noise!!! About 3 - 4 psi is optimum and is the fogure quoted in weber specialised books, good luck, den.

peirburg pumps are quality, quiet and can get them in a range of pressures. They can be a little bit more costly but thats what you have to pay for quality parts

i used i think a fuel-miser plastic pump "for 4 cyl" for my 32DMS weber... has a max of 3psi and worked fine... was a small round plastic cased jobbie (not much bigger than a fuel filter).. cost was maybe $70 (quite a few years ago)

those ones with lower max pressure would be better suited.. cos then you don't need to regulate it down or run a return line

thanks everyone - I think first thing I'll do is get a fuel pressure gauge - a wet one for use inside the engine bay, not a 'leccy in-cabin job.
Dropped into Sprint on the way home to get some prices - they'll ring me back.
Anybody got any views on the difference between in-line and T-piece (in/out vs a single in connection)?

cheers,

T piece is easier to install, not much difference in the pressure reading capability.
