Replacement Fuel Bladders for Chevron B19/21 Sports Racer?

[speedstar]

I am replacing the fuel bladders on a Chevron B19. The oval opening measures about 3 3/4" X 5 3/4". The original Marston bladders are very flexible and I guess they went in thru those openings. I need new bladders and the ATL, for example, are too stiff and bulky to go back in thru those holes requiring new, larger openings in the tub for access. Does anyone know of a source for bladders that might fit thru the smaller openings? Or, what have you done to fit new bladders in one of these car? Thanks, Don

Aerotech Services or Eagle fuel cells. They are the best bladder constructors in the US who's fuel bags most closely represent the style of the Marston cells. Have had great success with both their products in a variety of sports racers and formula cars (Chevrons, Lola's, McLarens, Ralts, etc)

Eagle will do a super job at a reasonable price and they will go in the opening. I have used them on several cars.

Don,
If you use a vacuum pump to collapse the bladder completely (and a generous amount of talcum powder), they'll fit!

Gentlemen, thanks for the responses. I am using Eagle ... very reasonable pricing. Don
