I'm planning out the surgery on the car and basically am making a paper outline of what goes where (and what gets cut)... Thanks, Bill P.

I would mount a Holley Blue pump under the tank much like your last car. Just remember that whatever you buy... check to see if it is a pusher or puller. Some are designed to push fuel..others do a better job of sucking. B

I would move it a little farther forward (next to where the radiator will be) Hang it on one of the bolt holes for the old bumper shocks (looks like a 75 tub) B

I guess the Holley pumps are pretty beefy versus standard 914-4's. Yep, its a backdated bumper '75. Good eye! Bill P.

Not when the pump is that close to the tank. One of the reasons why I said "move it forward" a little bit.. it will end up next to the radiator so it wont be blasted with hot air (just surrounded by it) This will become more clear as you start mounting the radiator.

I couldnt recall what year the car was. I looked at the car back in 2001 I think at a PacNorWest event in Oregon. Jamie Rust's event I think.. I have slept since then.

Thanks,

Bill P.

That's a stock (like in cheap) Chevy pump. No clearance issues at all. Since taking the picture I did put a short section of foam rubber pipe insulation between the pump and the hose to reduce heat transfer, not that it was a big deal. Engine block gets hot anyway.
Also, I wrapped the headers. Keeps the heat down and lots quieter.

That's cool. The pump has a bleeder on it. Interesting. B

I was planning on locating an electric pump on the engine firewall as many have but I hear the noise can be a problem. My mech pump on my 283 didn't get gas to the carbs for almost a minute. I suppose I could have replaced it with a higher volume type. I don't think the Renegade brackets allow for mech pumps.

Dont get them wet.. the wrap traps moisture and makes them rust VERY fast. For some reason the water wont all evaporate. I learned this the hard way. Now I ceramic coat everything (or buy the headers that way)

My thoughts on this: Most of those pumps are designed to be pushers not pullers. They are designed to be mounted next to the fuel tank in a front engined car. They can push fuel 13 feet if need be... but how well they suck is another question. I know they work (I've mounted them there).. just wasnt comfortable with it.

Hi Brad

I bet you're right. Mine are coated with Tech Line ceramic reinforced coating and not paint. I'm hoping this stuff holds up a log time. Plus, my headers don't get wet that much here in the desert.

I couldnt keep it on otherwise. It would slip down/off over time. I like the concept.. I just couldnt make it work without it looking like hell a month later. Cant wait to see this next project of yours done. B

B,

How do you tell which type? I like the near the tank location but don't people mount them under the tank where they are hard to get to?

Sorry for getting off the topic of fuel pumps ... but on the headers I used those stainless steels straps kind of like tie wraps. Hasn't slipped off yet. Yeah we're looking forward to seeing the new V8 completed. Engine goes in next week.

I would run one of the small rotary pumps on rubber isolators under the fuel tank.

Felix,

How often do you think you will be fooling around with the fuel pump ? ALL (after 74) 911's have their fuel pump mounted to the suspension cross bar directly beneath the tank. Easy to get to once the rock guard cover is off and the car is in the air.

Cool. They came up with a better design later on it sounds. I havent tried to use the stuff in 5-6 years.

Back to our regularly scheduled programming.
