Let's Talk About Fuel Pumps

While choosing the right pump for your exact application is going to be very specific, there are general rules that apply to nearly all street/strip systems. Here's the what and why of the pump we've decided to go with on our '68 Roadrunner.

Still here. Still paying attention. Thanks Tony!

Question: Why do I like Uncle Tony?

Answer: No pandemics and a shared love of Mopar cars.

I'll add a tip I learned, especially if you drive your hotrod a lot in hot climates and use a return line regulator: Do NOT oversize the electric pump by too much. Most of the fuel is being returned to the tank and is getting hotter and hotter as it circulates. Remote mounting the regulator out of the engine compartment helps, as does installing a cooler on the return line. But for simplicity, I switched to a pump that more closely matched the actual peak demand of the engine.

First repair I ever did by myself, Changed the fuel pump on my 69 Dart. Worked good.

Hi uncle tony thank you for all the good information on fuel pumps👍🔧🚘

[HereIsRick]

That Roadrunner is the coolest car you own (in my opinion) and I'm looking forward to future content revolving around it.

Wow Tony I haven't seen a crank driven fuel pump in 30 years. Your one of the best thanks again.

uncle tony going electric over mechanical? im crushed my life has no meaning now.

[petermajkovica]

I ran a holley red years ago in a 78 4dr C20 I stuffed a 4.3 V6 in with a Q jet and home built HEI, Mounted it on the frame up front and worked great as a puller.

This is amazing info to know, thank you for sharing your knowledge with us!

I think you missed safety on this one uncle T. An electric pump should also have a shutoff for when the engine isn't running...I always wire mine through an oil pressure switch..got to crank a little till pressure comes up to start the pump...but if you ever roll the car you don't want the pump still going.

I have the same intake on a 400 with 509 purple shaft cam, windage tray and milled heads in my sons 86’ 2wd ram charger. She’s a screamer 💯

I ordered the Carter 4070, ran 2 tees with a check valve in between so the pump can't feed a little into the tank, and I got a momentary toggle switch to prime that can also stay on if I want, relay with keyed ignition so it can't be turned on with the truck off, can't wait to install it!

Just here for the algorithm. Thanks for another great video Tony

I know it's two different things but, I love hearing the Mopar Starter whine and not start the first or second time and the third time it Rumbles to life, I am a purest and the sentimental feeling of how it was done in the 70's is pure Nostalgic Gold. My brother who is a "Mechanic" brought up the Idea of an Electrical Fuel Pump on my 70 Cuda.... after research of the Noise, connect to Battery, more Wires, Fuses, etc. it would have been a regret, goes to show a title does not mean common sense. Btw I looked up his horoscope and he should have been a bookkeeper Yup that says it all.
