Stock-ish fuel pumps

[daveismissing]

Anyone have experience with any of the modest pumps?

edits:
I see Eric has a house branded pump and an AEM,
Kirban has a Delphi and must be a Walbro,
Mike(full throttle) has a Racetronic house brand and a Walbro? ....
Highwaystars has the stock Delphi


I put a Deatchwerks in the other car, but it really is overkill in both situations.

Dave...if there's anything that should be overkill with these cars...it's the fuel pump. Even on a daily driver...yer' gonna wanna mash the loud pedal every now and again. When you do...you don't wanna come up short on fuel. If research shows these pumps you mention are made by top manufacturers. ..then I'd give them the green lite for those who ask.

Dave...yer' a good man. The little ladies car got the best.

I agree with the anything being overkill it being the fuel pump. I have a walbro me and Charles installed in 2012, and it's supplies the pressure just fine for what I'm running, but I get nervous nonetheless. After that bad batch they had some years ago, I just dont feel comfortable. Lol

Walbro 430/450 pumps are the way to go.

Dont those require modified return lines?

SOME guys are getting away with the stock return line up to a 340. Anything over that will require a larger return line to keep the fuel pressure under control. I use a 255 pump...just to piss people off.

I figured as much.

Doesn't look like it.

Use more fuel, return less.

Looks like it.

Hey, did anyone notice what the ad says? Rofl! Who says that?! Wat if I don't want to afford? Sayin' I'm poor homie? If i cant afford, mothafuckah!? Maybe I got ten over here layin' around for dog toys.

I could see them saying 'hey Rick, we got another broke ass over here, he don't need that other piece...'

Man, too funny!

I talked to a vendor about making JUST the larger return line. I'll be testing it in the spring. I'll likely jump to a 340 from the 255.

Brad I'd go with the -8 feed at the same time. You're going to have the tank down anyways, routing the line in the same place on the frame rail. Sending unit will have to come out to add an AN fitting for the connection. You might as well add the other AN fitting and bigger pump while its apart. Just a suggestion.

It's being made up as plug-n-play.

Well I'll be a monkey's uncle!  Why not just ensure this by putting a -6AN fitting on the damn sender... because that still looks like a 5/16" push fitting in the picture to me.  -6AN to 5/16" is not going to improve the return flow at all with a restriction anywhere in the system.  Unless the goal is to have some sort of short term volume gained in the line itself?  Maybe just install a surge tank on the return side to absorb the returned fuel for short bursts?

Fuck. I don't know. Whatever.

Guess I am going to have to put a -6AN return line in the Monte since I am planning on using a 450 and a stock-style GM hanger...

The Deatch with our stock lines seems OK so I guess it really must vary w the manufacturered variance. IIRC there was only one spot where the formed restriction was problemmatic?

Drilling out the Saginaw fittings was the cure for some from what I read.
