Hi all,

There appears to be a fuel pump issue with my '71 GTV1750 and I am thinking of switching to an electric pump. With many old cars still on the Kenyan roads, certain models of electric fuel pump are available for carb engines here. I did find some of the other past threads that have dealt with the location, set-up and sequence. Very useful. My questions, though:
1. Are there particular pressure and flow ratings to look for?
2. If installing an e-pump, do I need to do anything to where the mechanical pump had been connected to the engine block?
3. Are there any downsides to switching over to an e-pump? Should this be a last resort or will this be a positive move for the car's reliability and performance?

Many thanks.

Are you sure that you have a fuel pump problem?

I presume that you have checked the obvious things such as
the paper element in the fuel filter.

I have recently done this to my 69, bc even after replacing the mechanical pump I could not get it to work. I know I may want to fix this eventually, but this car is not bone stock anyway. So, you can leave the old non working pump in place, which it what I did...or you probably want to fabricate a block off plate.
I assume your car is carb'd....so a low pressure fuel pump is in order. The pressure should not be more than 3.5-4 psi.....The one I got is a Facet pump, rated at 1.5-4 psi, works like a charm!

I had some massive Jaguar 2-stage electric pump mated to my dual webers in my 69 1750 GTV, once spica now converted to dual Webers. Why do I have a dual race Jaguar 2-stage electric fuel pump thing, I'm not sure... that's the way it came on the car. Anyway, like most english stuff, it died... I was thinking to order this one:
Centerline Bendix Fuel Pump

This pump puts out 4.5-5psi. But now I'm worried that if I go bezerk on the race track / time trials / street I might need more fuel line pressure than this can provide. Maybe a higher pressure pump with a regulator that can be adjusted when I'm performance driving with the right foot glued to the floor? .... or am I completely insane to think I won't have enough pressure?

thanks for any input!

All these 1750 GTVs here are original Webber or converted to Webber.
My 1967 1750 GTV still has the original SPICA. My question is:
What is the flow / pressure rating of the 1969 SPICA ?
The cost of a 1969 Bosh pump is over $600, I am seeking alternative. If I upgrade the fuel pump to a higher pressure rating one alone, what will happen to the SPICA? Will the SPICA blow up or self adjusted.
Thanks in advance....

I didn't realize that these pumps cost so much there! Since in my Gt 1750 the old bosch unit died , I just replaced it with a new bosch like those in the photos and the result was amazing!I gave for both (one is spare) $300, new in the boxes.As for the fitment , wasn't a problem from the coaxial inlet/outlet not to mention that the new pump makes lower noise.
