Esteep Posted June 25, 2013 Report Share Posted June 25, 2013 I'm doing an sr20 swap and I want to use my stock fuel tank, my set up is a carburetor/lift pump to surge tank to main pump, but I don't have a return fitting for my return line. So my question, Could I remove the top breather hose from the tank and connect my return line there? How much would it affect my fuel consumption? any one ever try it? Quote Link to comment

hosestop@msn.com Posted June 25, 2013 Report Share Posted June 25, 2013 Are you going to use a 280zx replacement pump (external ) or some other ebay model, I use the feed at front R.side for return line 1/4 only for a return at tank or drill and make 3/8 male a&n ,and next part is dangerous and pay a PROFESIONAL to WELD a bung in rear center of tank ,spare tire area, for a 90 deg.3/8 o ring seat fitting to #6 A&N.

hosestop@msn.com Posted June 25, 2013 Report Share Posted June 25, 2013 The sr needs only a 5/16 hose I was overkill with 3/8 sometimes. Quote Link to comment

I'm using external pumps, the carburetor/lift 4-7psi pump I picked up at a parts store and I got an MSD pump for my main pump around 40psi, I was trying to avoid welding anything to it but if I have to I will. The sr needs only a 5/16 hose I was overkill with 3/8 sometimes. Yeah I'm going to use 5/16 lines as both pumps, surge tank and filter have 5/16 fittings. Quote Link to comment
hosestop@msn.com Posted June 26, 2013 Report Share Posted June 26, 2013 Hey bro really need that zx pump (I like rubber stock mount also) or oem pumps think 80 - 90 psi sr runs at 43 and boosted raises to 53 and a stock pump seems better with stock regulator on fuel rail will hang awhile just my two cents!
