Re: '87 tank/fuel pump supplier
You will need the Corvette filter/regulator. That rail you have is returnless, there is no regulator on it, that thing that looks like a regulator is a pulse damper, does nothing to regulate pressure.

Re: '87 tank/fuel pump supplier
LS1Nova, since its a returnless system, what do I do with the return fitting or portion of the corvette filter/regulator?

Re: '87 tank/fuel pump supplier
LS1Nova,
Is there anything out there that regulates while in-tank or in the sending unit/assembly that is a direct fit? |

Re: '87 tank/fuel pump supplier
For an '87 tank? Unfortunatly, no. The newer senders take a completely different type of lock ring and are bigger. I would just use the '87 tank and sender, get a Walbro255 pump or something similar and use the Vette filter.

Re: '87 tank/fuel pump supplier
James Jones,
I was taking a closer look at your 87 sending unit. Did make those fittings on top? For feed and return? |

Re: '87 tank/fuel pump supplier
Oh damn my fault. I was wondering how he got those fitting on it. I think mine will only have the slip on type. The one you use with good ole stainless clamps. Will I have to cut them, slip on a fitting and then use a flaring tool?

Re: '87 tank/fuel pump supplier
Boy do I need help!! This is a head scratcher for someone with my skill, or lack thereof. I finally got the 87 sending unit, tank, etc.... I hope someone can help.
So my understanding is that LSx engines use high pressure fuel systems(58psi), so what do I do with the sending unit's feed/return/evap lines? I mean it looks like it only takes the good ol' slip fitting that use the traditional hose clamps, isnt this NOT HIGH PRESSURE COMPATIBLE? wont they burst right off at the first moment the pump turns on? All your help is very appreciated, hell if you guys lived in Tucson, I'd buy you guys a round of cold beverages. |

Re: '87 tank/fuel pump supplier
87's were fuel injected, but it was throttle body injection which only runs at around 17-20 psi that's why they were just clamped. The barb on the end of the line will keep the hose on under pressure provided you use fuel injection hose and fuel injection clamps, I like to put two clamps on them with the screw parts opposite of each other. Many have been done this way, a couple of my cars included. If you don't feel comfortable with it you could braze on AN fittings, or if you're good with a flaring tool, you could cut the barb off the end and double flare it.You also could use nylon line with compression fittings as long as you can find the right fittings. Keep in mind you will need some kind of flexible hose, rubber, steel braided, nylon ect. so you can drop the tank if the need ever arises. If you hard line it to the frame, you won't be able to move it and trying to drop the tank will probably damage the lines going into the sender.

Re: '87 tank/fuel pump supplier
LS1NOVA,
I have already bought about 20ft of stainless braided TEFLON line with a bunch of hose ends for that stainless line. would the FI clamps work with the stainless line? Double Flaring seems to be a safer bet, but I dont think I have enough line coming out of the sending unit to work with, unless you believe its enought to double flare. Also, will those double flare fittings directly bolt on to the stainless hose ends? Last edited by LS-K; 01-31-2014 at 04:05 AM. Reason: SPELLING |

Re: '87 tank/fuel pump supplier
I used some 37* steel fittings, but I had to enlarge the ID to fit the sending unit pipe, then I silver soldered them to the sending unit.
I found the fittings over at the Parker Store in the area of Ajo and Palo Verde. He also has the female fitting,s BUT after you get the lines to the right length he will need to crimp them. Done Deal !!

Re: '87 tank/fuel pump supplier
What brand of sending unit is that? My spectra one had metric o ring fittings on it. The barbed style of this one makes me wonder if its a carbureted one...?

Re: '87 tank/fuel pump supplier
Can you tell me what size the fittings are on the sender? I want to order the connections from Summit.
