Gas pump for 1275

[longbridgehealey]

Hi everybody..I just received my alternator conversion kit from Moss, and I was going to tackle it this weekend, if the weather get above 40 degrees! It's for our Bugeye, which got a 1275 transplant last spring. So I've gotta switch it to negative, change the Petronix to a negative, and install the alternator. Here's my question. I was going to replace the fuel pump at the same time, and I understand that it cannot be solid state. What type of pump can I get at the local auto store that would do a good job for me? I kind of learn as I go, and you guys have helped me many times before, so thanks in advance!

I was able to get one from Advance Auto for < $50 that worked on Bugsy my '68 Sprite for years and years. Others favor SU's. Needs to be a low flow model < 3 GPM. Mounts above RR Wheel. Don't have model # here at work but others may be able to provide.

Hi Jim, thanks, that's a good start

I think Jim meant low pressure. I use an Airtex pump that is rated for 4.5PSI and it works fine.

Why can't it be "solid-state"?

Going by the conversion to alternator instructions that Moss sent me: "If the fuel pump is solid state it will have to be replaced". That's all I know...

I think maybe what they are thinking about SU type pumps. Call moss and ask. I have a Facet pump on my BE and works great. Make sure it is the low pressure one, around 2 psi.

 

[longbridgehealey]

Are you using an alternator?

To prevent any problems of over-pressurization of the very pressure-sensitive SU carbs, please consider adding a fuel pressure regulator if you switch to an aftermarket fuel pump. Even a low-pressure type like I have will cause problems without a regulator.

The Airtex is sold under a couple of different brand names but it is a low pressure type pump. Rated as < 3 GPM. Quiet, does typical LBC tick, tick, tick on startup when key is turned partway. Let's you know pump is sending fuel. Give it a few seconds and turn key rest of way to start. I did have two of these, one lasted a year, the other has been fine for > 4 years.

I chose a Carter P60504 (about $60 locally, $40 on-line). It is rated at 2-4 PSI (carburetor compatible) and crosses as OEM replacement for a lot of cars, and it is actually made in the USA.

Whenever I choose an non-standard replacement, I go for commonality and availability. I try to avoid anything that has to be ordered from a specialty house like Moss. This one comes with an inline filter and the case is isolated from ground - It can be installed in a positive or negative ground car. It runs continuously, so you hear a small buzz when the engine is not running.

DO NOT let that carter run dry. It'll burn out pretty fast. At least mine did.

I needed volume for the 1380 running a 45DCOE Weber. So, in the pre-build I manufactured a mounting plate and suspended a Facet aircraft pump on isolation mounts. The pump will be utilizing Filter King pressure regulator and filter to bring the pressure down to 3lbs.

Airtex E8016S - Finally found the box in the garage - $36.19 @ Rock Auto

I have an Airtex as a spare, and a Facet in the car, with a regulator.

Truthfully, for proper fuel pressure/flow regulation you need a return line to the tank, this will help keep the fuel cooler.

I'm using 2 of the Airtex pumps and like them. One on my BE and one on my midget. The pump that Blue Max is using is exactly like the Bendix pump that I had on my MGB that is still running after 100K and over 40 years! Facet has acquired the Bendix pump apparently. They claim it to be long lifed and my experience would agree with that.

OK, so it looks like it's going to be the Airtex. Thanks Jim, Trevor, and everybody! I'll post when the positive to negative conversion, the fuel pump and the alternator for generator is all completed. Thanks again

 

[Jim_Gruber]

You can repolarize the generator in about 5 seconds so it can work for negative ground. That won't stop the ability to get out and drive pending your alternator conversion. Just means you need to turn the battery around. When I got Bugsy my '68 Sprite - Ground car with a '66 + Ground Engine. DPO could not figure out why he could not get engine and fuel pump to run(Prior to AIRTEX). Turns out he had battery hooked up as + Ground rather than - ground. I turned around battery, turned key, heard fuel pump run, and Vroom, vroom noises heard. After that, grounding one of the terminals on the generator(not sure which, need to research if I need to do again) for a second completed the repolarizing process. That's all it took.

 

[longbridgehealey]

I was thinking about doing that, but I'm going to try to do it all in one sitting. We'll see how that works out
