hi all,
thought you might like to look at this site if you are looking for an electric fuel pump for your webers. Something to think about.

I use the Mitzuba fuel pump. Never failed and don't need a regulator. It does supply 120 L/h.

Chris,
these are dirt cheap in north america. The site has a price but we can get them cheaper at napa etc.

Interesting about the regulator.I was planning on buying that pump and running it with the filter king reg. Now I only am running twin SU's with a mod motor. My question is .Will $PSI and all that volume overwhelm the carbs if I don't run the filter king? Any ideas?

do you have to use an aftermarket fuel pump if you convert to Weber carbs (32/36 DGV's to be specific) or can you use the stock fuel pump?

No you don't have to. In fact I think a couple of members are running triple carbs with the stock.

I have three of those same pumps sitting on a shelf in my garage. Two came on a TR8 race car I bought and one was on a BMW 2002 with twin 40 DCOEs I had. They seemed to work very well. I also have several Facet pumps that I don't like. Both race cars now run a Barry Grant fuel pump with a regulator. Expensive, but they work great.

I had misfire on high revs with the standard pump.

Mad Max- I think Mr. Panic has a street machine and probably would do fine. Unless everything else is hot too then all bets are off!

High revs did mean...10 mls at 5000 rpm in one go.

My car does need 35 L / 100 km, so the pump must supply more than 70L/h. The standard pump (TR 4) does provide about 55L/h

I did some more reading about the Carter gp4070 fuel pump...seems like many people are fond of it.

Summit Racing carries it for $69.95...also available from Summit through their Amazon outlet for the same price.

While I was on Amazon, I was surprised to find that a search for Triumph Spitfire returned a LOT of items.

Since I am installing a DCOE on my 1500, I ordered the pump. Now I reckon I'll need to make a cover plate for my mech pump.

Len, you can either make a cover plate, or just leave the stock mechanical pump in place. I found the cover plate to be a convenient spot to add an addditional crankcase breather.

I read somewhere, it might have been in More B.S. About TRs, that, if you're going to bypass the mechanical pump, you should remove it. I think the reasoning was that the mechanical pump needs the fuel flowing through it for cooling, and, without it, will fry.

Besides, it's easy to make a cover plate out of scrap aluminum. Or whatever you have lying around.

I suppose that kind of makes sense, but I've never tried reusing one after bypassing it. I normally use the cover plate.
