Fuel tank recommendations for holly sniper II

[Leinhit]

1960 apache c10 with a Chevy 350

I have decided to go with a sniper 2 EFI unit for my project. I have already purchased it.

I do not have the original behind the seat gas tank any longer it was rusted out.

But I am lost on what type of fuel tank or fuel cell I should be using with this setup, I don't mind having a fuel cell sitting in the box of the truck. But is it possible to get a new behind the seat fuel tank and still find an in tank high pressure pump and sending unit for the sniper unit?

I prefer an in tank pump but I'm lost why a fuel cell that uses an exterior pump is only about $200. But the moment I look for a fuel cell with an in the tank pump it gets up to $1,000

What am I missing or what do you suggest? I was told to buy a regular $200 fuel cell and cut a hole to put in in tank pump in it, I'm not familiar with this but what setup would you use if you recommend this?

I would rather have a kit that is all ready to go but price is an issue.. $1,000 for a fuel tank and pump and a few lines seems like a lot if I could get it down to half that..

I feel like I'm missing something obvious here but my searching hasn't helped much.. the Holly website offers retro gas tanks with everything you need in it but of course not for a 1960 Chevy pickup

Advice and recommendations are appreciated

Thank you

You could source a 'remote' fuel surge tank that are available for retro EFI set-ups.

They are a small remote mounted tank w/a high pressure fuel pump in it that feeds the EFI supply/return. To supply the surge tank, you can use your old school mechanical fuel pump (it basically becomes a transfer pump). The high psi pump then picks-up the fuel transferred over @ low psi & sends it to the throttle body @ the correct/required psi.

Or.... There are many aftermarket in-tank solutions for rear or bed mounted tanks.

The 'behind the seat' tank w/an 'in tank' pump can be done but I don't know of any 'kit' to get it done. Keep in mind if you opt for that you get to listen to the pump if you're wanting that. Many opt for an inline external pump under the cab & add a return line to the tank (again, no 'kit' that I'm aware of).

I appreciate the reply,

I think I can't get everything I want, it's one or the other.

For ease of insulation and cost it's probably going to be best to get a external fuel cell and mounted in the bed on top since my new exhaust runs between the frames straight out the back and they are in the way. The only other answer I came up with is cut my exhaust and turn it to come out behind both rear wheels freeing up the area between the frame back there for a tank, but I really don't like the idea of cutting brand new exhaust off..

And an exterior fuel pump is probably going to be best in this case and maybe a future upgrade can be done.

I would like the tank behind the seat but I need the high pressure system and not sure how to rig up a return line to it. And as you pointed out I don't want it pump right behind my seat listening to that the whole time.

Low psi external electric pumps have been used for years w/o issue. High psi rated pumps are put through the ringer in comparison because they generate a lot more heat. This is where an internal survives longer because of the reduction in temp.

Try the external inline & see how it goes. My bet is if you drive it a lot, you'll do an internal set-up @ some point. Since you're using a sbc, the remote surge tank is the combo I would consider.

I was able to use a '92 S10 Blazer tank in the rear of my '60 Apache. It's 20 gallons, F/I ready with a built-in pan/bowl and the sending unit will accept an AC Delco EP381, Walbro, or even Aeromotive fuel pump. Another OEM option would be an '87-'95 GM full size van F/I tank. I'm currently installing this one in a '66 short bed.

[Leinhit]

See that's really the best answer the only thing holding me back is I have my brand new dual exhaust running right through there...

I'm just having a hard time coming to terms cutting the exhaust and maybe turning them out behind the rear wheels...

I know overall it's probably a dumb reason to hold back, but it was just so expensive and then to go and cut it...

But I like your idea and suggestion.. did you get a junkyard used one or did you buy a brand new one somewhere?

I see Holly and others offer retrofit gas tanks all set up for fuel injection but of course they don't have one for a 1960 Chevy... I started wondering if some other year or model that fits behind the seat that they happen to have would work but I didn't play around with the various years and models to see what's out there yet

You wouldn't have a photo of your setup when you install it do you? Either of the Blazer fuel tank or the van fuel tank..

I am a little sticker shocked by the brand new price of the fuel cell pumps and unit etc so maybe a junkyard deal would be the way to go especially if I could find a poly one.. I do need the return line though for the Holley sniper 2..

69 Camaro tank here with a Holley drop in fuel pump in my 66. No return line required and filler neck behind a fold down plate.

I think it will be tough to make an in-tank pump work in the in-cab fuel tank. One it will need a unique, smaller opening to fit it all through, two it will need a very long hanger, three that tank is not baffled so when low on fuel it will slosh away on turns and starve the pump.
I would find a tank that mounts between the frame rails under the bed and then use a Tanks Inc PA series in tank pump. This eliminates the slosh issue too. https://www.tanksinc.com/index.cfm/p...prod/prd84.htm

Verdell, can you tell us more about your setup? You have a short bed, correct? So there should be even more room in a long bed, am I correct to assume that? How is your exhaust routed? Where did the fill hole for the tank end up?
Thanks!

Yes, my '60 is a short bed fleetside. Because I'm still running torsion bars, the muffler shop had to get creative with routing the exhaust, so it doesn't tuck as close to underside of the truck as I'd like. For the next phase, I plan on redoing the exhaust with frame cutouts to address that but for now it works fine. Currently running 2.5 inch with Magnaflows dumping right out back. The fill hole is currently in the bed floor towards the driver's side. Years ago, I had the filler mounted in rear wheel tub. I plan on going back with that set up after my new Oak bed wood is installed.

Thank you verdell. Nice to know the exhaust can still run to the rear. I imagine it gets pretty loud in the cab with them dumping in front of the tires whenever folks go that route.
Is the tub fill harder to fab than the more common bed fill?
Thanks!

I think dumping at the axle or in front of the rear tires would drive me mad or it's old age setting in!

No, it wasn't very hard. I took the entire fuel fill door from an '83-'94 S10 Blazer or another flat shaped fuel fill door, cut it out of the donor vehicle and welded it place on the wheel tub. Depending on the amount of space in the rear wheel housing, you'll need to modify a fuel neck or source what you need. This was at least 15 or so years ago and I don't have any photos..

I was at a local car show and a guy had a '60 GMC there with a 90's S10 Blazer tank under the back. He said it was an aftermarket kit that he got.

I had previously mounted a 90's S10 Blazer in the back of my '61, and was surprised to see others using the same tank.

Bottom of THIS PAGE I show the tank mounting

VIDEO I did featuring the fitment.

[Leinhit]

Okay thanks for the info,

I will definitely check out that video tonight.

Here's a quick photo of what I got to work with with my exhaust in the way I'm not quite sure even if I turned it to come out behind the rear tires if I would have enough room for a between the frame tank. I was picturing basically a square tank that would Mount between the frame all the way to the rear but not sure I'd even have enough room turning the exhaust out

Sorry for the late response.

I just installed my Sniper kit with the supplied external pump mounted to the rails and the original tank behind the seat. They recommend 3/8" line from tank to Sniper, I found a 3/8' pick up from Tanks Inc (https://www.tanksinc.com/index.cfm/p...rod/prd712.htm). The tank was from LMC and they have a return port option in the top passenger side corner. I ordered some 3/8" line and a tube bender and fabricated some solid lines then matched it in with some Earls 3/8" Vapor Guard hose from the kit also.

It works, guess I'll see how long for but I am happy with the result so far.

Can you share pictures of your setup?

The engine bay, CD module and coil are on the left inner fender. Hyperspark distributor also.



Sniper mounted on an Offy 4 barrel with an adapter. I drilled out the adapter plate mounting holes so I could turn it 90 degrees and put the linkage on a straight pull.



Used the original throttle linkage, just trimmed it up a little for aesthetics. You can see the fuel line and pressure gauge in the back. I used 3/8" Vapor Guard hose from the pump on the rail to the Sniper.



Supply and return lines, inline filter on the supply. I used 3/8" tubing to go from the tank, through the floor and to the rails and also on the return. This bought me a little more room than trying to stuff 2 runs of the Vapor Guard hose through the floor - without cutting the floor up, or having the hose rub. Once the tube gets to the rail I used the hose to the pump, from the pump to the Sniper and the return line also.



Supply line from the 3/8" tank pick-up running through the floor. The return line on the left also, I switched to the Vapor Guard hose just for ease of install. This was my first attempt at forming these steel lines and didn't want to mess around too much. As it was, I finished all of this and my neighbour came over asking how it went. Then asked if I used a coat hanger to get the length and angles. I felt stupid right about then. I had read about it, but in my haste forgot everything about that part.
