whats the best fuel pump to buy for my 305 tpi swap and where should i get it from?
anyone have a used one for sale?

 

a stock replacement wil work fine for your 305 swap. If you feel you want a better name brand pump then Holley and Walbro make good pumps as well. Its all on how much you want to spend. I would NOT, I repeat, NOT install a used pump. Its just not worth the hassle. Buy a new pump and be done with it. you may also want to check on the replacement pumps for the GMC syclone and typhoon as the pumps used in those trucks should also work in your car. Buy a new O ring seal for the tanks sending unit while your in the dept. Follow the directions to the T and all should go well. DO not jam the sending unit in the tanksince you will bend the float lever and throw off the gauges accuracy.

PS.

PS. DO NOT CUT A HOLE IN THE TRUNK AREA TO ACCESS THE PUMP. DO IT THE RIGHT WAY.

 

the gauge isn't very accurate anyways, i get like 100 miles out of the first 1/4 tank and then like another 100 out of the next 2/4

 

I left the stock pump in the tank on my RS and just did an inline. Works great and gettin the needed 50ish psi needed to run the TPI that I changed over to

 

its a big job on some on ours, can anyone tell y they wouldnt cut a hole. i heard that you have to take the rear end out, and on mine i would have to take the exhaust out.

 

first off its not worth it because in order to get the entire sending unit with the pump out of the tank, you would need to cut a massive hole in the car. The HARD lines come out of the top of the sending unit and travel along the top of the tank toward the fronf of the car. they then bend downward behind the seat a little bit so you would need to cut a hole out that big in order to pick the sending unit straight up without bending or ruining the hard lines. Trust me, its not worth it. Take my word for it because I tried a long time ago. Your thoughts of this 8"x8" square hole turn in 20x20. Then you have to weld it back in there when your done and thats not the easiest thing to do some people.
I know it sucks to drop the rear and pull the exhaust off but it is the only proper way of doing this procedure.

 

well is another good opinion would be to leave the stock one in the tank and just put an inline one in, i am new to the fuel deliver thing

 

I wouldnt add an inline pump. I would just replace the tired or busted pump with a new one in its stock location. I dont claim to be an engineer or anything in this dept but I think you will making things worse with an line pump. Someone tell me how you can have one pump pushing and then 3-5 feet down the line have another pump sucking and pushing at the same time.

PS, I mean maybe I am wrong here but I think it would just be easeir to install the proper replacement pump and be done with it

 

shoot, now i am stuck with a Dilemma, i am all about doing it right, but i dont have much time. i go to school mon thru thur. work fri and sat and church sun. hardly never any breaks. my car now, my pressure at the rail is good, flow=bad. its a stock 350 .030 over, shorties true duals, mods later, maybe engine even later, need pump for this and probably have to get a regulator then. after exhaust was done, got a code for lean exhaust

 

welcome to the real world of building cars as a hobby. Get a few more opinions on this and then go from there. dont take my advice as the only advice out there.

 

yeah i know, thats what makes it fun you have a 383, an engine that i would love to have and it sounds like you have done it, that is an expert in my opinion

 

This site will help you out a ton with any questions you may have. its helped me a ton over the years and has allowed me to do all the work on my car myself. Now Im guessing you have a 305TBI and are now swapping to a 305 TPI right? Maybe this question you have willbe better answered in the engine swap section of this board. Give it try over there?

Oh and why in the heck are you putting another 305 back in the car. a 350 can be found anywhere for cheap money. ALL of your parts will fit the 350.

 

its a 350 tpi bored .040 over in there right now, sorry i have been saying it is .030 over

 

ohh well in the first post you said 305.

 

I encourage folks to go to a high volume pump if they are doing any mods of any consequence, especially adding Nitrous.

 

hairbear said that not me, my first comment is y you wouldnt cut a hole and that i heard that you had to take the rear end and exhaust out

 

FWIW, I am running the Holley pump in my car. Its either the one in this link or one VERY similair to it http://store.summitracing.com/partde...5&autoview=sku

 

i was looking at that one as well, i could tune that down for fuel deliverly to a 350 couldnt i, would computer do that or get a pressure reg.

 

you will need an adjustable fuel pressure regulator to control the pressure to the PSI you need

 

cool done deal then, thanks by the way i am slow what is fwiw, not use to the short versions besides like lol and imo

 

for what its worth.

 

ha ha ok im pathetic i know
